According to the number of cylinders of the pump: according to the number of cylinders of the pump, there are single cylinder, double cylinder, three cylinder, five cylinder, etc. The main components of the slurry pump are composed of pump casing, pump body, impeller, pump seat, coupling, support cylinder, clutch, gearbox, power drive, motor seat, electric motor, pressure gauge, cleaning valve and other parts. The volute, pump seat, motor seat, and impeller nut are cast iron with good corrosion resistance and convenient processing technology. The impeller is three-piece single-circular-chord curved blades, semi-closed impellers and malleable cast iron are used, so it has high strength and corrosion resistance; it is easy to process, good through, and efficient. In order to reduce weight and reduce the amount of turning, the pump shaft is made of high-quality carbon steel cold drawn steel. The pump seat is equipped with four skeleton oil seals and shaft sleeves to prevent shaft wear and extend shaft life.
