multistage water pump

The High efficiency multistage water pump is a horizontal segmental multistage centrifugal pump with single suction or double suction inlet. The suction port of the pump can be arranged vertically upward or horizontally, and the discharge port can be arranged vertically upward.  mainly includes: water inlet section, middle section, water outlet section, secondary water inlet section, positive guide vane, reverse guide vane, positive impeller, reverse impeller, shaft, throttling, pressure reducing device, retaining sleeve, bearing body, transition pipe and other parts.

The middle section is connected by high-strength through bolt and water inlet and outlet section, and the sealing surface between the water inlet section, middle section and water outlet section of the pump is hard sealed by molybdenum disulfide grease metal surface.

 

The rotor is composed of positive impeller, throttling and pressure reducing device, reverse impeller, shaft sleeve, bearing sleeve and other parts installed on the shaft;

The working chamber of the High efficiency multistage water pumpis composed of water inlet section, middle section, water outlet section, secondary water inlet section, positive guide vane, reverse guide vane, transition pipe, etc;

A sealing ring and guide vane sleeve are installed between the rotor part and the fixed part for sealing. When the wearing degree of the sealing ring and guide vane sleeve has affected the working performance of the pump, they should be replaced in time.

The shaft sealing forms include mechanical seal and packing seal. When the pump is sealed with packing, the position of the packing ring should be placed correctly, the tightness of the packing must be appropriate, and the liquid can seep out one drop at a time.

All kinds of sealing elements of the pump are installed in the sealing cavity. The cavity should be filled with water of certain pressure to play the role of water sealing, water cooling and water lubrication. A replaceable shaft sleeve is installed at the shaft seal to protect the pump shaft. 

        

The High efficiency multistage water pump can replace the bearing and seal without removing the inlet and outlet pipes.            

The High efficiency multistage water pump is directly driven by prime mover through elastic pin coupling or diaphragm coupling. Viewed from the direction of prime mover, the pump rotates clockwise.
