I. General introduction
The FQU series pumps are the corrosive resistant pumps, which are fully made of total engineering plastic. The structure of the pumps is very simple. The main features of the pumps are as below:
1.The engineering plastic parts of the pump are formed by inject casting. They are light, non-scale with excellent corrosion resistance.
2.The end of the shaft is built in the impeller by casting. The pumped medium won not contact the metal shaft.
3.Equipped with special corrosion resistant mechanical seal. The leakage is greatly limited.
4.High efficiency because of the direct connection structure of the pump.
5.Pump body is supported by a simple metal support.
6.Simple in structure. Easy for assembly, disassembly and maintenance.
The FQU series pumps are widely used in chemical industry, non-ferrous metal industry (gold, silver, copper, lead, zinc, cobalt and nickel etc.), metallurgical industry (pickling, manganese industry),chemical fiber industry, titanium dioxide industry, rare earth industry, insecticide industry, phosphorous fertilizer industry, citric acid industry, paper industry, desulphation, food industry, water treatment and environment facilities. These pumps are the ideal pumps for pumping clean corrosive liquids. The working temperature of the pump is 80 ºC if material of the pump is FRPP (fiber reinforced polypropylene). The working temperature can be increased to 120 ºC if the material of the pump is PVDF.
The FQU pump can be used in the explosive condition if it is equipped with an explosion resistant motor.
