2 General your reliable pumpchoice With experience from industrial fluid handling and pump manufacture since 19, we know what you as a customer require from an industrial pump. Ever since we started our manufacture of air operated diaphragm pumps, we have always had our winning concept in mind: to create pumps for reliable duty and with a minimal number of components enabling easy maintenance. We are always keenly aware of new requirements and ideas from our customers. The products are therefore always in continuous progress with improved detail solutions, new materials and further accessories. Tapflo quality The Tapflo pump is usually an essential part in the process with hazardous fluids. We always strive to supply the safest and most environmental friendly solution for these fluids. As a part of our safety thinking, we are in the frontline following important standards, guidelines and directives. Many of our products comply with the EC ATEX directive for equipment in explosion hazardous environments. All our pumps are of course CE marked and followed by our comprehensive instruction manuals. Tapflo is an ISO 9001:001 certified company. The EHEDG certification of our aseptic diaphragm pump was achieved in 009. The history of Tapflo Tapflo was founded in Kungälv (north of Gothenburg), Sweden 195 and has since then been working with design and manufacture of air operated diaphragm pumps. The product range has grown from a few plastic models, to complete PE & PTFE, metal and sanitary series and lately also with complete ranges of centrifugal pumps. Tapflo has now established sales offices in 0 countries and independent distributors in another countries - spare parts and pumps are available worldwide.

3 General How Tapflo pumps work The Tapflo diaphragm pump is driven by compressed air. The two diaphragms, connected by a diaphragm shaft, are pushed back and forth by alternately pressurising the air chambers behind the diaphragms using an automatically cycling air valve system. Pumped liquid Compressed air First cycle... Second cycle... Suction (1) One diaphragm creates a suction action when being pulled back from the housing. Discharge () The other diaphragm simultaneously transmits the air pressure to the liquid in the housing, pushing it towards the discharge port. During each cycle the air pressure on the back of the discharging diaphragm is equal to the head pressure on the liquid side. Tapflo diaphragm pumps can therefore be operated against a closed discharge valve with no adverse affect to the life of the diaphragms. 1 1 Some benefits with Tapflo pumps Thanks to the simple operating principle, with a compact and reliable construction, Tapflo diaphragm pumps meet the demands of heavy industrial duties. Below are some of the major benefits of Tapflo pumps. Feature Run dry without damage Infinitely variable flow control Few components Self priming up to 5 m from dry suction pipe Solid, strong and long life design Lubrication free air distribution system No electricity needed Air operated Benefit Easy to use, no need of guarding device Flexible and easy to adjust Low down time and maintenance costs More options of installation Low maintenance costs Saves the environment from pollution Explosion proof versions Ex-zone 1 available (ATEX group II, cat ) Can run against a closed pipe or closed valve without damage. Easy to install without special training (no electricity) 6

4 General How to install Tapflo pumps The Tapflo pumps are flexible in their ease of installation. The in- and outlet ports are infinitely turnable more than 1 in to fit your piping system (PE & PTFE and metal series pumps). Flooded The piping system is designed with a positive suction head. This is the best way of installtion where it is necessary to completely evacuate all liquid from the container, or where viscous (thick) products are transfered. Selfpriming The Tapflo pump is designed to pull a high vacuum. It is able to evacuate an empty suction pipe without any damage to the pump. The suction lift is up to 5 meter (16. ) from an empty suction pipe and up to meter (6. ) from a wetted pipe. The suction capability depends on the pump size (see pages 17,, 9) Submerged All Tapflo pumps may be submerged into the liquid. It is important to make sure that all components which are in contact with the liquid are chemically compatible. The air exhaust must be led to the athmosphere by means of a hose. 7

General Key components of the Tapflo pump Three major components are especially vital for the function of the pump.

Tapflo diaphragms are of sandwich compound construction, superior for continuous heavy duty service.

This results in no leak through and a diaphragm which is easy to keep clean.

5 General Key components of the Tapflo pump Three major components are especially vital for the function of the pump... Long life diaphragms The two diaphragms are doing the work to prime and push the liquid through the pump system. Tapflo diaphragms are of sandwich compound construction, superior for continuous heavy duty service. The solution with an integrated metal core, provides a completely smooth surface in contact with the liquid, without any nuts or washers. This results in no leak through and a diaphragm which is easy to keep clean. The diaphragm is available in PTFE (food grade), EPDM, white EPDM (food grade), NBR (nitrile) and FKM (viton, on certain models only) Cutaway PTFE diaphragm 1) Reinforcement webbing ) Light metal core 3) EPDM layer ) PTFE layer Pollution free air valve The air valve is the driving heart of the pump, distributing the compressed air to the chambers behind the diaphragms. It is made for maintenance free duty with no lube air, thanks to the ingenious sealing system. It will not only save your money for lubrication, it will also save your environment from pollution. The Tapflo air valve has no deadlock position the pump will always start automatically when air is supplied to the pump. The valve body is made from brass or optional PET or stainless steel AISI 316. Ball check valves The Tapflo pump is fitted with four check valves, making sure that the liquid is transferred in the right direction through the pump. The valve is of ball valve type, the most simple and reliable valve design. It has a good sealing capability and is easy to keep clean and to replace if necessary. The valve ball is available in EPDM, NBR (nitrile), PTFE, AISI 316, polyurethane and ceramic to suit any kind of liquid. 9

Special versions TF filterpress pump stations The Tapflo pump station for filterpress feeding is a very compact unit that can be mounted directly to the filterpress.

10 Special versions TF filterpress pump stations The Tapflo pump station for filterpress feeding is a very compact unit that can be mounted directly to the filterpress. The design and function allows the user a straightforward pressing of slurries. Pressure regulator is already mounted to the unit. The pump stations are based on the standard Tapflo pumps from machined polyethylene (PE). An external pressure booster doubles the delivery pressure. For example, with available air pressure of 7 bar, the delivery pressure will be maximum 1 bar. The installation As this station works self-regulating, an additional device for regulating the flow quantity is not necessary. Just mount it to the filterpress, connect it ready. Even the pressure regulator for the air supply is included. For monitoring the filling-level of the filterpress, stroke sensors and stroke counters are available.
