A. The pump base is made of cast iron, the foundation is firm, and the base is not easily deformed

B. The ordinary pump adopts the three-claw coupling, which is easy to disassemble; the sprocket coupling is used for conveying high-viscosity medium

C. The seal adopts domestic high-quality mechanical seal, Harbin bearing

D. Cast iron, cast steel, 304, 316, 316L materials can be used for overcurrent parts according to user needs

E. The main parts are tested for physical and chemical properties, and the main parts under pressure are tested for hydraulic strength.

F. The test medium is mechanical oil, and the test pump is gradually boosted at the rated speed to run at the rated pressure. After the type test of each pump, the pump should be disassembled and inspected to check the wear of the running parts of the pump. .

G. The processing capacity of G screw rotor is unmatched by other domestic screw pump manufacturers, and its processing capacity and processing accuracy have reached the international advanced level. At present, our company can process various profiled screw rotors with a diameter of 10-630mm and a length of 90-6000mm.
