Pressure switch BGA pumps are equipped with a sealing system with double tandem mechanical seals with intermediate oil chamber, connected to an oil reservoir. The plug of the reservoir includes a special vent valve. In normal conditions, the reservoir is always at atmospheric pressure. In case of leak from the internal mechanical seal, the flow of liquid makes the vent valve to close putting under pressure the reservoir. This way, by means of a gauge and a pressure switch we can have an immediate detection of the problem without spillage of product.

12 BGD NEW SELF-PRIMING PUMPS FOR LPG PATENTED An innovative design to guarantee: Top performance Top safety Easy maintenance

13 BGD NEW SELF-PRIMING PUMPS FOR LPG Exclusive features of BGD series: This pump is an absolute breakthrough in the field of self-priming LPG pumps. It is a multi-stage pump that operates according to a new principle. It consists of a set of side channel type stages with star impeller to which a special volumetric self-priming stage is connected on the suction side. The result is a pump with a much higher suction capacity than any other existing pump. In normal conditions, priming time is reduced by one third, thus eliminating downtimes in product delivery. In particular conditions, such as: > Crityical systems because of high suction gradient or with vertical tank; > Systems affected by periodic pumping problems due to climate or the product pumped. In all these cases, the BGD pump solves the problem, guaranteeing regular functioning. The highly-efficient volumetric self-priming stage guarantees fast, trouble-free suction of the gaseous phase of the product which is always present in the pipes at any start of the pump. So the pump does not require any external degassing device, thereby simplifying the system and reducing the related costs.

14 BGD NEW SELF-PRIMING PUMPS FOR LPG With regard to safety, the pump is fitted with an anti-spillage system that makes it possible to monitor any leak from the mechanical seal without product spillage, thereby eliminating one of the major risk of LPG plants. Another unique feature of this pump is that each element is sealed using O-Ring gaskets where other pumps adopt flat gaskets and sealing glue. The O-Ring guarantees perfect seal and, above all, fast, easy pump disassembly and re-assembly. This close coupled pump is fitted with bell housing and drive coupling which guarantees simple, safe connection to the electric motor. The motor pump is vibration-free and very silent with a sound level of less than 70 db. The pump has steel made, slip-on flanges DN 32 PN 40. ATEX Certification Ex II 2G T4

18 VSG 20 BY-PASS VALVE FOR LPG Exclusive features of VSG 20 valve: The by-pass valve VSG 20 type is a multi purpose valve designed for use in LPG pumping systems. Installed on a LPG pump, the valve performs a double function: a) starting the pump, the valve enables the vapours to leak out from the pumping system; b) when the pump primes, the valve limits the maximum pressure of the pump. The valve has steel made flanges, sliding type, DN 20 PN 40 Operating limits: Temperature: -20 C / +60 C Maximun pressure: bar 40 Differential pressure range: min 10 / max 20 bar Max flow rate: 100 l/min

23 series SBF PUMPING UNITS with submersible Motor Pumps for fuel delivery Indispensable in large service stations to take advantage of the delivery capacity of Multidispensers.

24 series SBF PUMPING UNITS with submersible Motor Pumps for fuel delivery Submersible Motor Pumps: Submersible motor pumps for fluel distribution system have been used for many years and their success is due to the advantages they undoubtedly offer compared to traditional systems. They represent the most rational solution to supply fuel dispenser and are indispensable in big, modern Service Stations. The Series SB/F Pumping Units are the result of a refined and innovative project that has led to significant product development and establishes a new standard in the field of submersible motor pumps for fuel. Detailed tests regarding performance and characteristics of the Motor Pump, the Discharge Head and the relative Leak Detector Valve VRF 4, confirm that the Series SB/F Pumping Units are unique in that each individual component is of the highest standard and, in some case, these are decidedly innovative.

26 series SBF PUMPING UNITS with submersible Motor Pumps for fuel delivery Discharge head: The design of the head is strealine and rational, featuring unique constructive characteristics: ll caps have O-ring seals. The internal parts can be reached easily and quickly, seal is always perfect and maintenance times are drastically reduced. A large basket strainer protects head parts and all components situated downstream of the pump against impurities. This is obviously of great advantage to overall system management, where liquid impurities are one of the main causes of problems. The outlet is directed in a downward position and is equipped with a flange with O-ring seal. This system enables simple connection to underground piping, even in confined spaces, and guarantees problem-free seal. The equipment also copries a vent screw for a manual pressure relief, extremely useful to bleed to zero head and line pressure, preventing products during maintenance operations.

27 series SBF PUMPING UNITS with submersible Motor Pumps for fuel delivery Leak detector valve VRF 4: This is a piston valve designed to perform various functions, the most important of which is to signal any leaks from the delivery pipes. As regards this function, the valve is characterized by the test execution time, (less tha 5 sec) and the large internal capacity, capable of compensating the product's thermal volume changes. The valve also has a built in Venturi System in the cap together with the relative suction and discharge connections. The Venturi enables the valve to execute siphon priming in order to empty two or more tanks using the same pump. When the pump stops, the valve adjusts the head pressure for the Unit, limiting it approximately 0,7 bar, by means of the Venturi discharge. The valve also performs an effective air bleeding function. Each time the pump is activated, any air present in the discharge head is bled within a few seconds by means of the Venturi System discharge, thus ensuring delivery of a degassed product.
