I. General introduction　

FCU series engineering plastic corrosion resistant side suction pump is to use the company the original FLU series engineering plastic filter pump hydraulic model, combined with the characteristics of the working conditions of filter press carefully designed a specially designed for press filter matching the corrosion wear resistance of high lift side suction horizontal centrifugal pumps, its main characteristics are as follows:
1, use suction side structure (pump inlet in the side of the pump), medium into the pump
between the impeller and shaft seal，then No matter how high the pressure inside the pump chamber, shaft seal is always in a state of negative pressure, greatly improve the the reliability and life of the shaft seal.
2, Adopt unique structure design, make the side suction located on the bearing seat directly, pump head positioning on the side suction side again, in this way, not only simple in structure, assembly and disassembly is very convenient, the most main is to ensure that the concentricity of the shaft sealing, improve the reliability of the shaft seal. Overcome the defects of the other manufacturers use extended opening type bearing seat, side suction location on pump head so that the complicated structure, inconvenient installation and concentricity of the shaft sealing is difficult to guarantee，then affect the sealing effect.
3, All the parts of the pump, which are in connection of the pumped liquid, are made of ultra-high molecular weight polyethylene (UHMWPE), which has excellent corrosion resistance, abrasion resistance (The best of the plastic) and anti-impact property. Plate structure is used to pump head, pump casing, pump cover using the structure of the mold to suppress all plastic is very thick, not only the internal and external corrosion, and are more resistant to abrasion, long service life.The structure is more resistant to corrosion, and more durable than other manufacturers plastic lining structure.
4,The pump and filter press in matching, stop using the pump,pump cavity of a large number of solid particle deposition, affecting the next boot, so this series of pumps in the pump body set up with flushing tap holes,to facilitate emptying liquid in the pump cavity after stop the pump,
and rinse to improve the durability of the pump.

II. Application

Because of its unique side suction type design, FCU series engineering plastic corrosion resistant side suction pump especially suitable for non-ferrous smelting industry in particular, lead, zinc, gold, silver, copper, cobalt, tungsten, rare earth industry such as wet smelting of pressurized feeding of filter press,of course, also can be used for all kinds of acid, pulp, slurry, electrolyte, sewage and other medium transport. This series of pump not only can replace the
domestic similar metal and nonmetal products in the above industry, is also the preferred product localization of import equipment.
