2 ACTIVE REMEDIATION F.A.P. Plus Pump System ACTIVE REMEDIATION F.A.P. Plus Pump System Active pneumatic skimming system for product recovery Application LNAPL Recovery. DNAPL Recovery. 2 inch or larger wells. Recover a wide range of products from lightend hydrocarbons to more viscous products such as #6 heating oils. Description The F.A.P. Plus Pump system is comprised of seven main components: F.A.P. Plus Pump Skimmer Assembly Well Clincher Filter/Regulator (not shown) Pneumatic Overfill Protection Device Electric Air Compressor (not shown) Hoses (not shown) Options: SolarNAPL Compressor F.A.P. HF F.A.P. Plus Pump (TR-516) The F.A.P. Plus Pump consists of a flexible, special inner bladder and a flexible Buna-N hose which forms the outer pump body. The integral controller is housed inside the stainless chamber and is factory preset for 15 cycles per minute. This provides the optimum pumping rate. The pump operates by alternately inflating and deflating the annular space between the inner bladder and the outer hose. When compressed air is applied, the inner bladder collapses. When the air is exhausted, the inner bladder rebounds to its original shape thereby causing a suction which pulls fluid into the pump and up to the surface. The pump utilizes two check valves to maintain the suction and prevent the fluid from flowing back into the well. The pump is capable of producing a suction of 17 in of mercury for the recovery of viscous product and operation in deep wells up to 200 feet. The F.A.P. Plus can operate dry or in the coiled position without damage. It may be installed at the surface in shallow well applications. Skimmer Assembly The skimmer is attached to the bottom of the F.A.P. Plus pump and is used to separate the product from the water in the well. Depending on your site conditions, three types of skimmers are available: standard, high viscosity and density skimmers. The following table will help you select the proper skimmer for your site. Viscosity 80 SSU or less Higher than 80 SSU D from BW to PWI " Water Table Flu < 36 < 24 < 30 < 24" Well Diameter 2 2 4" 2" Part Number TR-517 TR TR TR-702 Skimmer Type Standard 36" travel Standard 24" travel High Viscosity Density Tech Tip: For recovery of sinkers, the DNAPL skimmer (TR-519) attaches to the bottom of the F.A.P. Plus Pump. Tech Tip: The high water shut off can be added to the TR-517, TR and the TR to insure water is not recovered should the water table change exceed the skimmer travel. Standard Skimmer (TR-517). The standard skimmer is used to recover gasoline, jet fuel and most diesel fuels. It combines a density float, a special hydrophobic element, a product bypass, a hollow guide rod and a coiled hose. The center guide rod allows the skimmer to travel freely in 2

3 Section 1 ACTIVE REMEDIATION F.A.P. Plus Pump System response to the water table changes. The skimmer is designed to float with the inlet positioned at the water/product interface automatically providing 36 of skimmer travel. The density float is used to position the special hydrophobic element the skimmer inlet at the product water interface. The hydrophobic element uses a special micron pore size that is based on surface tension, allowing only product to pass. A larger pore size is available for use with higher viscosity products such as weathered diesel. Pumping rates through the hydrophobic element will be approximately 100 gallons per day. 2 in. Well Clincher TR-762 F.A.P. Plus Typical Installation Air In Discharge Out Air Exhaust Air Filter/Regulator Assembly TR-748 Pneumatic Overfill Device TR-757 Tech Tip: The larger micron-sized elements may allow a small percentage of water to pass. The bypass element is attached to the top of the hydrophobic element and allows the product to enter the skimmer directly when the product layer is greater than 2 inches. Recovery rates through the bypass element are approximately 300 gallons per day. The complete skimmer element is connected to the bottom of the guide rod by a coiled polyurethane hose. This coiled hose can accommodate water level changes of up to 36 in automatically maintaining the skimmer intake at the water/product interface. A minimum distance of 24 in from the bottom of the well to the water/product interface is required when using the TR-517. The TR requires a minimum of 18 in and provides 24 in of travel. The skimmer can also be configured as a passive device by attaching a quick connect canister on the bottom of the skimmer, providing greater flexibility for free product recovery projects. (see Passive Skimmer on page 9). Maintenance: Biofouling may occur because the hydrophobic element is positioned at the air/product interface. If fouling occurs, the element can be cleaned using a soft brush or replaced by unthreading the bypass element and installing a new hydrophobic element. FAP Plus Pump TR-516 High Water Shut Off Product Bypass Hydrophobic Element Density Float Skimmer Assembly TR-517 Product Storage Tank Air Compressor in Non-Explosive Atmosphere TR-901 Floating Product Groundwater High Viscosity Skimmer (TR-70410). This skimmer is used when the product has a viscosity higher than 80 SSU, such as oils. The 4 in high viscosity skimmer uses the same design as the TR-517, less the hydrophobic and bypass elements. The skimmer has a 30 in travel and a specific gravity of 0.95, allowing it to float at the water/ product interface. The product collects on the top of the skimmer inlet and, from there, is pumped to the surface. In normal applications the skimmer will remove product down to a ¼ in to ½ in product layer. The skimmer can be adjusted in the field to remove the product even further and attain a thinner layer. Density Skimmers (TR-704, TR-706, TR-712). Density skimmers are used when there is less than 18 inches of flu- id from the bottom of the well to the water/product interface. These skimmers have a specific gravity of 0.95 and float in the water with the top inlet just above the product/water interface. The skimmers have an effective travel of 24 inches. The 2 in and 4 in sizes are for use in well casings with these nominal inside diameters. The 6 in and 12 in models are self-supporting and may be used in large diameter wells, open excavations and open water applications. High Water Shut Off (TR-51710). This option can be used on all the rod skimmers, TR-517, TR and TR It is used when the water table changes are expected to exceed the travel of the skimmer. When the skimmer reaches its upper travel limit and is submerged in water, the pneumatic logic shuts down the pump and will restart the pump 3

4 ACTIVE REMEDIATION F.A.P. Plus Pump System when the skimmer returns to its normal operating position. Tech Tip: It is important to ensure that water table level changes do not exceed the travel of the skimmer, or water could be collected. The High Water Shut Off, TR-51710, should be considered in these applications. When installing the system, it is also important to account for the rise in the water table due to removal of floating product. Water tables can rebound over 20% when product is removed. Well Clincher The Well Clincher has expandable, pass-through fittings for the air supply and fluid discharge hose, allowing the pump to be easily adjusted. The Well Clincher seals the well from debris and is available for wells with diameters from 2 to 8 in. Filter/Regulator The regulator allows the pump operating pressure to be set according to the depth of the pump. A minimum of 60 psi is required to operate the F.A.P. Plus pump properly. The filter regulator is included with each F.A.P. Plus pump. Well clincher and filter regulator in simple field installation. Pneumatic Overfill Protection Device Electro-Pneumatic Overfill Protection Device This device uses an intrinsically safe float sensor to shut off the air supply to the F.A.P. Plus pump. It includes a programmable 24 hour timer to allow on/off time settings in 15 minute increments. A 115 V power supply is required. Air Compressors and Membrane Dryer An electric, non-explosion-proof 2.5 hp, indoor-use air compressor producing 4.2 scfm is supplied with the standard F.A.P. Plus Pump System (TR-515). This compressor can be used with up to three F.A.P. Plus systems. A 5 hp compressor is available for use with more than three systems. If other air sources are used, they should include a 5 micron coalescing air filter. In freezing or high humidity conditions, an air dryer is required to avoid system damage. The Membrane Dryer (TR-749) is a good choice for use with the F.A.P. System. The F.A.P. Plus pump requires relatively dry air for optimum performance. Refer to line sizing chart on page 33. Hoses The standard hose size from the outlet side of the filter regulator to the F.A.P. Plus pump is a ¼ Push-Lok fitting and a 3/8 in barb fitting on the air inlet side. The standard F.A.P. Plus fluid discharge line has a 3/8 in barb fitting. The hose sizes may have to be increased depending on the distance between the system components. How do I select the most appropriate skimming system? The most important elements in choosing the F.A.P. Plus system will be your water table fluctuations, product viscosity, type of product, well diameter and amount of product present. You can find the complete design data sheet on our web site to define all of your site conditions. This device is installed on the recovery tank or drum to prevent overfilling the product storage vessel. The overfill device is installed on the storage vessel and will thread into a standard 2 in bung. The main air is supplied to the inlet side of the overfill device and the outlet air supply to the F.A.P. Plus pump. The overfill device senses a pressure differential when the storage vessel is nearly full and shuts off the air supply to the F.A.P. Plus pump. The standard overfill device can be used with three F.A.P. Plus pumps. The TR is used with more than three F.A.P. Plus pumps. TR-757 Options Tech Tip: The F.A.P. Plus requires a minimum of 60 psi for optimal performance SolarNAPL Solar-powered air compressor configured to drive an optional F.A.P. Plus pump. See page 6 for details. F.A.P. HF To pump at higher flow rates (up to 2.2 gpm) with a suction of 17 in Hg at the inlet. See page 13 for details. 4

6 ACTIVE REMEDIATION ESS Electrical Skimmer System ESS Electrical Skimmer System Electric skimming system for product recovery. Application LNAPL Recovery. DNAPL Recovery. 4 inch or larger wells. Tech Tip: For 2 in wells, the pump can be mounted at the well head. Description Explosion proof Skimmer Pump Nema 4 Control Panel Skimmer Electric Skimmer Pump (TR-104). The ESS skimmer pump is a linear dual solenoid reciprocating piston pump that uses an internal piston and dual check valves to create suction transferring the product from the skimmer to the surface. The pump is equipped with a standard 100-foot power cable with NEMA 6P rated connections. The pump has a maximum depth capacity of 90 feet and can produce flow rates up to 150 gal/day. The discharge hose connection is a 3/8 in barb fitting. The pump itself is rated explosion proof and must be installed to Class 1 Division 1 electrical codes to maintain this rating. Skimming Pump Controller (TR-105 Series). It is used to control the run times for one to three skimmer pumps. The controller has three independent 24-hour timers with options for: Manual Pump Off, Manual Pump On, Auto Off cycle timer and Auto On cycle timer. To simplify operations, the pump run time is set based on the recovery rate of each well. When used in the auto cycle mode, the pump timer must be set allowing a 50% off time compared to the on or run time to maintain optimum pump life. The controller is housed in a NEMA-4 enclosure and is not rated explosion proof; therefore, it must be located outside the explosion rated area. The controller includes the tank overfill device and will operate on 110 V, 60 Hz or 230 V, 60/50 Hz. Standard Skimmer (TR-517). The standard hydrophobic skimmer attaches directly to the bottom of the pump via a quick connect fitting and provides 36 inches of automatic skimmer travel. The pump uses the same skimmer as the F.A.P. Plus system. The standard TR-517 skimmer is used for product with SSU values smaller than 80. For values greater than 80 SSU, the TR must be used.

7 Section 1 PASSIVE ACTIVE REMEDIATION Passive Skimmer PASSIVE REMEDIATION Passive Skimmer Floating inlet automatically adjusts to water table changes. Application Passive LNAPL recovery Use when minimal product is present or slow recovery rates are expected 2 in and larger wells May be upgraded to an active system by adding the F.A.P. Plus Pump. Description Skimmer Canister Well Clincher with 30 ft cord Skimmer. The Passive Skimmer utilizes the F.A.P. Plus skimmer to provide a 36 in floating intake for the recovery of free phase products such as gasoline, diesel and jet fuel. It is used when minimal product is present or slow recovery rates are expected. For passive recovery of products with higher than 80 SSU, the 4 in high viscosity skimmer (TR-25410) is used. This system provides a floating intake of 30 inches. Product Recovery Canister. The clear PVC collection canister uses a quick connect fitting to attach it to the skimmer and provides venting through the skimmer support hollow rod. The bottom of the canister incorporates a petcock for easy draining. The petcock assembly can be removed allowing an extension canister to be threaded into the existing canister to increase the volume of free product that can be recovered. Additional weights are included with each canister and must be used for proper installation. TR-252 Well Clincher and Cord. The Well Clincher and 30 ft Nylon suspension cord are used to support the passive skimmer in the recovery well. The clincher incorporates an eye hook to attach the suspension cord. Correct measurement of the product water interface is necessary to properly position the passive skimmer. Tech Tip. The critical measurement for proper recovery is from the bottom of the well to the product water interface. Custom canisters are available for shallow well applications.

8 PASSIVE REMEDIATION SoakEase SoakEase Absorbent material for immediate response or minimal product. Application Passive LNAPL Recovery. Rev. 01/08 Description 8 36 in Canister Absorbent Socks for 1, 2 and 4 in Canisters SoakEase is a product-selective absorbent sock housed inside a stainless steel canister. It is used as a passive collection system for free phase product such as jet fuel, gasoline or diesel fuel from 1.25 in and larger recovery wells, monitoring wells and recovery trenches. The SoakEase can be used as a bailer for periodic product removal or as a dedicated system for a more continuous method of recovery. Prior to dedicating the SoakEase, it is recommended that excess free product be removed by bailing with the SoakEase. To use SoakEase as a bailer, an absorbent sock is placed in the stainless steel canister; a cord is attached to the support loop and then lowered through the product layer. The full length of the sock should come into contact with the product for greater recovery. Immediately, the SoakEase will begin absorbing product at a rate of approximately 0.1 gallon per second, depending on the product viscosity. After some time, the SoakEase should be raised from the well; the sock removed from the canister and disposed of in accordance with regulations. To use the SoakEase as a dedicated system, determine the amount of product present and the water table fl uctuation using the PWI interface meter (TR-921). When these have been determined, the SoakEase may be installed to accommodate level changes up to 36 in. Tech Tip: The product absorption rate is determined by the viscosity of the product and can vary depending on site conditions. The SoakEase is designed to be used with hydrocarbon-based products. The user must determine the necessary replacement schedule by gauging site conditions. The socks can be squeezed out and reused. Approximately 80% of the original absorption can be recovered.

10 SUBMERSIBLE PUMPS MVP Series SUBMERSIBLE PUMPS MVP IV Series Pneumatic Pumps Controllerless air lift pump Application Controllerless ground water pump for use in 4 inch and larger diameter wells and up to 200 feet depths for: Dissolved Phase Total Fluids Plume Control Dewatering Leachate MVP IV Pump Description The MVP IV pump kit includes: MVP IV Pump Well Clincher (well cap) Air Particulate Filter Regulator The MVP IV Pump uses an internal float that responds to the fluid level within the pump body to cycle the pump automatically, based on the recharge of the well. As the pump fills with fluid, the float moves to the upper position, activating the mechanical arm which opens the air inlet valve. This allows air to enter the pump chamber, simultaneously pressurizing the vessel and closing the upper and lower inlet check valves. As a result, the fluid moves to the surface. As the fluid is emptied from the vessel, the float returns to the lower limit off position closing the air inlet and opening the air exhaust valve. During the filling cycle, air is vented through the exhaust port and the cycle is automatically repeated. The thread together design provides complete access to all the internal components. This makes it possible to change pump loading configurations easily. The pump head can be easily removed should access to the air inlet and exhaust valves be needed. Positive Valve Shifting The air inlet and air exhaust valves are incorporated on the same side of the pump to impart a mechanical advantage which makes the valve shift fully and reliably. This leverage is seven times greater than would be available if the valves were located on opposite sides of the pump head. The new free-floating actuating arm ensures a positive air valve shift. The design permits the use of larger and simpler air exhaust valves to eliminate air quality and stalling concerns. The poppet design valves provide a larger surface area improving air efficiencies. Every MVP IV pump includes the override feature allowing the pump and discharge line to be emptied from the surface reducing the Magnet Actuating Rod Float Discharge Air Exhaust Air Inlet Pump top with body removed to show how mechanical advantage is achieved in the valve actuating design. pump s weight during its removal. An additional ¼ in air line is required. Tech Tip: Maintenance of the MVP IV pump will vary based on site conditions. For sites with high mineral concentrations, it may be necessary to remove the pumps periodically to clean the mineral deposits. The MVP IV features an all-stainless steel linkage system with Teflon bushings with a synthetic glass resin float to insure reliability and chemical compatibility. Stainless steel floats are optional. For added durability, all MVP IV pumps have a stainless steel body. The MVP IV pump uses clampless barb fittings for the 3/4 in discharge and 3/8 in air exhaust lines. The air supply uses a 1/4 in PushLok fitting. Quick connect fittings (TR-80910) are available as an option. Tech Tip: In deeper applications, the size of the air exhaust and fluid discharge lines may be increased to reduce friction loss and increase flow rates. Lever Flow rates range from 8 gpm on top-loading pumps to 13 gpm on standard pumps. Pump flow rates will be affected by the amount of head above the pump. Should lower flow rates be required, the flow control valve TR-698 can be installed on the exhaust line of the MVP IV pump. This will allow the user to restrict the air exhaust which regulates the fill time of the pump. It is important to properly size the air supply and discharge lines to accommodate for friction loss. Refer to line sizing tables on pages 33 and

11 SUBMERSIBLE PUMPS MVP Series Loading Configurations Top loading pumps are selected for pumping total fluids (LNAPL and ground water simultaneously). The top loading pumps will produce flow rates of up to 8 gpm depending on the head above the pump. Water table drawdown will be maintained at a level corresponding to the top inlet of the pump. Shorter length pumps are available for lower drawdown requirements. The Well Clincher serves as a well seal and pump support. It simplifies hose connection. A retractable handle provides for easy installation or removal of the pump system. The 90 degree fittings on the top of the Clincher reduce the possibility of kinked hoses in the well vault. Expandable Well Clinchers with pass-through ports are available for installations requiring frequent pump adjustments. TR-773 Tech Tip: A skimmer attachment (TR-810) can be threaded onto the top inlet of the pump allowing the pump to collect product only. Bottom loading pumps are selected for dissolved phase, DNAPL or leachate applications. When installing the pump, the head is positioned at the depth of the desired water table depression. During start-up, the pump fills from both the top and bottom inlet ports. As the water table depression zone stabilizes, the pump will fill from the MVP IV Pumps. Left: Bottom Loading model Right: Top Loading model bottom only. The bottom loading pump can be configured with a closed top to reduce the possibility of debris entering through the inlet. This may be particularly useful in leachate applications or applications where floating debris is present. View animated graphics on our web site. They show how the pumps function. There are links on the pumps' page. Tech Tip: Minimum submergence can be reduced on the bottom loading pump by installing the stop collar on the float actuating rod (TR-7714). This will reduce the float travel and open the air valve with less fluid in the pump. The top loading pump submergence can be reduced with a short pump. The Particulate Filter/Regulator should be installed at the well head to supply the proper air pressure to the MVP IV Pump. This will optimize air consumption. A good guideline for setting the air pressure is 0.5 psi per foot of pump depth. Tech Tip: Air consumption of the MVP IV pump is based on the depth and PSI setting. For a simple calculation use 1 cfm per gallon pumped. This is the maximum the pump will consume. Accessories: The Pulse Counter is used to determine the flow rate of the MVP IV Pump. The newly designed counter is compact and is installed in the air supply line at the well head. As the pump cycles, the counter senses the drop in air pressure indicating the pump has cycled. The number of cycles is multiplied by the volume of the specific pump TR-778 you are using to provide the flow rate. The counter is not resetting. The standard hose assembly (TR-777) consists of a 3/4 in Buna-N discharge line, a 1/4 in Nylon air supply line and a 3/8 in Buna-N air exhaust line. The Buna-N hose provides a flexible, chemically compatible discharge line. The main air supply and fluid discharge hoses should be properly sized to minimize head loss due to line friction. 11

12 SUBMERSIBLE PUMPS MVP Series MVP Pneumatic Pump Lower cost alternative The MVP Pump is identical to the MVP IV Pump except that the MVP Pump head and bottom valve assemblies are manufactured from Delrin instead of stainless steel. All other components are interchangeable. Delrin is a rugged, lightweight, high density plastic that is chemically compatible with the fluid in most applications. The MVP Pump provides a cost effective, high performance system. MVP LS and MVP LD Leachate and Condensate Pumps These models are specifically designed for use in landfills where leachate or gas condensates are recovered. They feature an air override that allows the pump and discharge lines to be emptied from the surface prior to pump removal. The MVP LS is a stainless steel bottom fill pump with a closed top and stainless steel fittings. The MVP LD is made from stainless steel and Delrin with a bottom fill, closed top and PVC fittings. Operation of these pumps is identical to the standard MVP IV Pumps. They can be supplied with custom Well Clincher flanges designed to meet your specific site requirements.

14 SUBMERSIBLE PUMPS Evacuator II Evacuator II Pneumatic Pump High Flow Controllerless Groundwater Pump Application For 2 in and larger diameter wells and up to 200 ft depths for: Dissolved Phase Total Fluids Plume Control Dewatering Leachate Description The 2 in Evacuator II Pump System includes: 2 in. Evacuator II Pump Well Clincher for use in vacuum operation 5 micron Coalescing Air Filter/Regulator with autodrain The Evacuator II Pump uses down-well internal logic combined with a small diameter float to automatically cycle the pump, eliminating the need for additional controls at the surface. For the 2 in diameter pumps, this logic technology allows the pump to use a much smaller float and fewer components than those using a mechanical type of design. Hence, this pump, with just a 33 in length will produce flow rates up to 4 gpm in the bottom loading configuration. As the pump fills with fluid, the float moves to the upper position activating the pneumatic logic. This opens the air valve located in the well clincher allowing air to pressurize the chamber, closing the check valve and pushing the fluid to the surface. When the fluid is evacuated, the float falls to the lower position where it activates the lower logic opening the air exhaust port. As the pump fills with fluid under static pressure, the air is exhausted and the cycle is repeated until the water table reaches the desired drawdown. The Evacuator II is constructed from stainless steel with a Nitrophyl float and Viton seals providing chemical resistance for most applications. Complete access to all internal components is provided with the three-piece thread-together construction. Maintenance will vary based on the site conditions. Conditions with high mineral concentrations may require routine cleaning. The Evacuator II style pump requires good air quality and an air drier is recommended. It is important to ensure that all air lines are purged to remove debris prior to start-up. Loading Configurations Top loading pumps are selected for total fluids applications, the recovery of LNAPL and ground water simultaneously. Fluid enters the top inlet and the water table will be maintained at this point. The top loading pumps will produce flow rates up to 2.5 gpm, dependent on the head above the pump. Bottom loading pumps are selected to pump dissolved phase product, DNAPL or leachate. When installing the pump, the head of the pump is positioned at the depth of the desired water table drawdown. Bottom loading pumps will produce flow rates up to 4 gpm. View animated graphics on our web site. They show how the pumps function. There are links on the pumps' page. The Well Clincher is an integral part of the system and serves as a well seal, pump support and houses the air control valve. The underside of the well clincher has color coded, PushLok fittings for the air logic line connections and barb fittings for the 1/2 in air supply and 5/8 in fluid discharge hoses. A 12 in chain is provided to attach the pump support cable. The air supply and fluid discharge lines are easily connected to 90 0 fittings on the top of the clincher. The built-in handle makes it easy to lower or remove the pump. A coalescing air filter and regulator assembly is included with each Evacuator II Pump system. This must be installed at the well head Top Load Bottom Load Evacuator II Pumps. Left: Top Loading model Right: Bottom Loading model 14

Therefore the greater the depth, the higher the air consumption of the pump will be. The Evacuator II Pump will use approximately 1 cfm of air per gallon pumped at depths of up to 50 ft. To determine the air consumption, use the following guilelines: 40 psi 0.8 scfm 80 psi 1.7 scfm 60 psi 1.2 scfm 100 psi 2.1 scfm Tech Tip: To reduce air consumption the air logic valve can be installed in the down well hose assembly above the water table. This is especially beneficial for deep application preventing the air from being exhausted back to the well head. Please consult Durham Geo Slope Indicator for ordering information.

16 SUBMERSIBLE PUMPS SEP IV SEP IV Electric Pump Systems Higher Flows in Ground Water Recovery Application Dissolved Phase Leachate Plume control Dewatering Flow rates up to 75 gpm Depths up to 400 feet. Description producing flow rates up to 75 gpm and to depths up to 400 feet. Other pump ends are available. The SEP IV Pump System consist of three components: the pump end, the pump motor and the motor lead. Selecting the most efficient system for your site requires the following information: total head desired flow rate well depth well diameter chemical compatibility requirements Use the pump curves to match your flow rate and total head to select the pump end that best meets your requirements. The curve will indicate the motor horsepower required. Select the motor leads for your well depth. The SEP IV Pump System consists of: Stainless steel pump Electric motor Motor lead The SEP IV is a continuous-duty electric submersible pump designed for the withdrawal of contaminated groundwater or leachate in environmental applications. The pumps require a control mechanism such as the Septek to maintain the desired drawdown level. Stainless Steel Pump The SEP IV pump ends are constructed of 304 stainless steel to provide chemical compatibility for typical environmental installations. Standard pump ends are supplied with durable PBT (polybutylene terephtalate) seals for chemical resistance in most cases. PBT seals are not recommended for use with chlorinated solvants in which case Teflon seals are recommended. PBT seals generally provide better wear resistance than Teflon. DGSI Teflon seal kits are available for all SEP IV pump ends. Note: Teflon seals will reduce flow rates by 10%. The SEP IV standard pump ends are available in eighteen standard models, 16 Left: Bearings with sand channels. All PBT standard bearings are water-lubricated and have a square shape enabling sand particles, if any, to be flushed out of the pump together with the pumped fluid. Left: SEP IV Pump System.

The motors are available in single phase 230 V, three phase 230 V or three phase 460 V. The three phase motors are used when the pump speed will be variable. Other motors are available upon request. Single Phase three-wire pump motors require the use of a control box containing a starting capacitor and relay. The three-wire motors provide a soft start and may offer better service life in deep well or in conditions where the motor requires higher torque to start. The two-wire motors use an internal bi-metal switch to start the motor. Motor Lead Motor leads are supplied separate from the pump end and motor assemblies. DGSI manufactures standard PVC leads in continuous lengths with no splices and individually insulated. The motor lead assembly can be supplied in Tefzel, a material that combines superior mechanical toughness with an outstanding chemical inertness. It is important to confirm chemical compatibility before choosing your motor lead type. Motor leads are 12-gauge wire with either two- or threewire leads plus the ground.

SEP IV Control Panels Electrical level control system TR-586 Internal workings Controller shown with optional SEP IV pump DGSI can supply UL-approved control panels for your specific requirements. All of our panels meet or exceed NEMA standards. The panels may be configured using variable speed drives allowing the pump speed to match the recharge rate of the well. Multiple pumps may be controlled by a single panel. Simple ON/OFF control panels may be provided using float sensors or pressure transducers to activate or deactivate the pump. Please call for specific details. (R) Typical assembly showing the SepTek (above) connected to an SEP IV pump (bottom). The SepTek is a mechanical down-well device used with electrical pumps to maintain a desired water table drawdown for extended periods. Installation is easy. Simply place the SepTek in line above the SEP IV or other electric pump exactly where the desired water level is to be maintained and walk away! The SeptTek/SEP IV Combo will do the rest. No need for cycling submersible motors on and off. No expensive relays, no VFD S, no throttling valves. It s simple and maintenance is low. When the pump is activated, the internal float will respond by directing the liquid to the surface or recirculating it in the well to match the fluid output to the recharge rate of the well which maintains the desired level. The pump will operate continuously, increasing the motor life. The SepTek system provides for full fluid discharge with no head loss or restrictions. It is constructed of a PVC body, brass bypass valve, cast bronze and stainless steel linkage. TR-586 SepTek with 1-in Inlet and Discharge 22 lb 21

22 SUBMERSIBLE PUMPS Fluid Level Control PumpSaver Submersible pump protector Three-phase PumpSavers PumpSavers are optional pump monitors designed to protect single- or three-phase submersible electric pumps from dry wells, dead head, jammed impellers, rapid cycling, over/under voltage, and, depending on the model, other conditions. They protect 2- or 3-wire pumps from 1/3 hp to 3 hp. Single-phase PumpSavers PumpSaver, TR-2604 PumpSaver, TR Informer, TR Single-phase PumpSavers measure the power factor, voltage and current. These measurements are collected and analyzed by a microcontroller which, under precise conditions, trips a built-in relay to shut off the pump motor to prevent damage. Three-phase PumpSavers combine a voltage relay, an underpower relay and an electronic overload relay into one device to provide optimal protection. The underload trip is based on power which is desirable when the current vs. load characteristic in non-linear or has little change which is the case with these relatively small motors. A calibration adjustment allows models TR-2601 and TR to be calibrated to specific pumping applications, thereby reducing the possibility of false or nuisance tripping. When an abnormality (such as would occur in a loss of suction) in power fluctuations, overcurrent, or undercurrent is detected, The PumpSaver deactivates its output relay and directly disconnects the pump motor. The unit then begins its user-selectable re-start delay (dry-well recovery) timer. When the timer counts to zero or power is removed and reapplied, the PumpSaver reactivates its output relay and turns the pump back on. An infrared LED can communicated directly with the Informer (sold separately). The Informer is an optional diagnostic tool for use with TR-2601 and TR This hand-held device reads values from the LED on the PumpSaver and displays 15 parameters including real-time voltage, current, and power; dry-well and overload trip points; calibration voltage; voltage, current, power at last fault; highest/lowest voltage and current since last calibration; model number. Note: The use of restrictors or unusually high head pressures at the time of calibration may interfere with the detection of dead head conditions. Typical wiring diagram for TR

Because it uses the sun s energy a renewable resource as the only power source necessary to operate recovery pumps, the SolarRem system is particularly friendly to the environment. Installation Advantage SolarNAPL System (TR-51600) The SolarNAPL System is configured to provide an air source to power the optional F.A.P. Plus pump skimming system for product recovery. The system uses a solar panel to charge the special AGM deep cycle battery specially designed for use in solar applications. The battery powers the internal DC compressor. The control panel includes a PLC allowing the operator to set system On/Off times consistent with the air requirements of the pump. The On/Off times are user defined and based on the amount of product to recover, the well s recovery rate, and the F.A.P. Plus pumping rate of approximately 0.18 gpm. The standard SolarNAPL will recover between 15 to 25 gallons of product per day depending on its location. Systems are designed based on hours of sunlight. Additional solar panels and batteries may be required to achieve optimum performance for your specific site. Contact Durham Geo Slope Indicator for recommendations on solar panels and battery ampere-hour capabilities for your site. Tech Tip: The SolarNAPL control panel is not rated for use in XP areas. For application such as inside tank farm berms, the units can be pole mounted above the XP area. The standard SolarNAPL System includes the NEMA 4 control panel, a 7.5 gallon air receiver tank, one 100 W solar panel, a 105 A h Advanced Glass Matte (AGM) battery and the Tank Full shut-off. The Tank Full shut-off turns the air supply to the pumping system off when the product tank is full. The F.A.P. Plus Pump (TR-516), skimmer (TR-517), solar panel mounting pole (TR-51613) and the bracket (TR-51615) must be purchased separately.

28 LOW FLOW SAMPLING Mini Bladder Pumps LOW FLOW SAMPLING Mini Bladder Pumps (MBP) Specifically Designed for Low Flow Sampling pump. The annular space is pressurized using the controller and the liquid is gently lifted to surface. All pumps can be supplied contaminant free. Application Low-flow ground water purging and sampling 1/2 in and larger-diameter schedule 40 wells Description The MBP pumps consist of: PVC or SS outer body Teflon bladder ½, ¾, 1, 1.3 and 1.66 in dia. The pneumatic Mini Bladder Pumps are designed to obtain a representative ground water sample with the assistance of a controller to provide variable flow rates. The controller allows the user to match the pumping rate to the well recharge rate, limiting the stress on the formation. With the small volume per cycle, the fluid velocity at the pump inlet is substantially reduced, making the pumps ideal for low flow sampling. The high efficiency design enables pump rates from 5 ml to nearly 2 L/min when used with one of our Precision Dual Range Controllers. The 1.66 in diameter pump will produce flow rates up to 2 gpm. Tech Tip: The amount of pump submergence will affect the pump flow rate. Pump curves were developed with 10 ft submergence. The bottom inlet of the pump is positioned at the desired sampling point, generally at the mid section of the well screen. The inner Teflon bladder will fill with fluid based on the submergence of the Models for wells down to ½ in and depths to 400 ft. Stainless Steel or PVC. Tech Tip: In portable applications, the pump is easily decontaminated by submersing it in a cleaning solution such as Alconox. Then the pump is cycled to circulate the solution through the internal components. This method avoids the need to replace bladders after each use. Dedicated assemblies can be supplied to reduce cross contamination, well disturbance and facilitate installation. The pump, tubing and well cap assemblies are plastic bagged and each assembly is identified with your well ID number and the well depth. Contaminant-Free Certification Upon request, ground water sampling pumps may be supplied as certified to be contaminant free. The rinse water from the equipment is analyzed by one or all of the following methods by an independent and accredited laboratory.

38 ANNEX Compressed Air Air Compressors We can supply air compressors for all types of environmental applications. From 3/4 HP oil-less designs for ground water sampling up to 15 HP models for remediation projects. Selecting the optimum air com pres sor system will ensure effi cient operation and reduce the need for main te nance and repairs. A correctly sized, good quality air com pres sor will provide years of trouble free operation. Two factors need to be considered when selecting the op ti mum size and type of compressor, air volume and pressure. The air volume required, usually ex pressed as CFM (cubic feet per minute). This is the actual volume of air delivered by the compressor as measured when dis charged to the at mo sphere at a set pressure. Once the CFM re quire ments have been determined, the com pres sor can be selected. It is im por tant to allow for a 50% duty cycle for the compressor to prevent the system from cycling continuously. (See Tech Tip Below) An after cooler will reduce the temperature of the com pressed air. This will result in the water vapor condensing into droplets which will collect in the bottom of the receiver. An auto drain fi tted to the receiver will open automatically, allowing the water to drain. Tech Tip: Formula for determining total air fl ow (cfm) requirements: Total cfm required x 1.5 = Total cfm Example: If you are using two MVP IV Pumps each producing 3 gpm (1 cfm required per gallon pumped), your actual air requirements will be 6 cfm. Multiply this number by 1.5 (50% duty cycle) and your total cfm requirement will be 9 cfm. A compressor will turn approximately 7 cubic feet of ambient air into 1 cubic foot of compressed air. The net result is seven times as much moisture and con tam i na tion inside the com pres sor receiver and air lines. The com pres sion process will also increase the ambient tem per a ture of the air inside the receiver. Air com pres sors can generate over 20 gallons of water in an 8-hour op er at ing period. If not removed, the mois ture and contaminants can cause premature failure of the air lines and pumping equipment. Com pres sors should there fore include the following accessories: an aftercooler, a receiver autodrain and, depending on the climatic conditions where the com pres sor will be used, an air dryer.

39 ANNEX Pressure Loss (Water) Air Dryers Air dryers should be used when the compressor is operated in freezing or high humidity conditions. In both cases it is necessary to remove as much moisture as possible from the air supplied to the pumps. There are three types of drying systems available: Refrigerated Regenerative Desiccant Membrane Refrigerated dryers are selected when the air temperature will remain above 350ºF. Desiccant dryers are preferred in low temperature conditions below 350ºF. Membrane dryers are usually chosen for applications where there is relatively low air consumption. Refrigerated Dryers Refrigerated air dryers use mechanical refrigeration to lower the air temperature of the compressed air. This lowers the dew point that causes the moisture in the air to condense into liquid and be removed from the compressed air stream. Regenerative Desiccant These dryers use a dual tower design, each filled with a desiccant media that will remove water from the air stream. The dual tower design allows one tower to dry the air while the other tower is regenerated. Maximum bed life is from 3 to 5 years. These dryers consume about 10% of the air supply produced by the compressor for regeneration of the desiccant bed. Membrane Dryer The compact membrane dryers use a molecular design that can provide atmospheric dew points as low as 400ºF. The system comprises densely packed hollow fiber membranes to diffuse the water vapor. No power source is required and the only maintenance needed is the periodic changing of a pre-filter element when the indicator on the dryer shows red.
