Single stage double suction pump, used for pumping clean water or other liquids with physical and chemical properties similar to water. The temperature of the transported liquid shall not exceed 80 ℃. Suitable for factories, mines, urban water supply, power stations, farmland irrigation and drainage, and various water conservancy projects.

Structural description of single-stage double suction pump

The suction and discharge ports of a single-stage double suction pump are both located below the axis of the water pump, perpendicular to the axis in a horizontal direction. There is no need to disassemble the inlet and outlet water pipes and motors during maintenance. From the transmission direction, the water pump rotates clockwise (or counterclockwise according to user needs).

The main components of a centrifugal pump include: pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, etc.

The centrifugal pump body and pump cover form the working chamber of the impeller. On the inlet and outlet flanges, there are pipe screw holes for installing vacuum gauges and pressure gauges. The lower part of the inlet and outlet flange of the water pump is equipped with a screw hole for discharging water.

The impeller that has undergone static balance verification is fixed on the shaft with a shaft sleeve and two side shaft sleeve nuts, and its axial position can be adjusted through the shaft sleeve nuts.

The centrifugal pump shaft is supported by two single row radial ball bearings. The bearings are installed inside the bearing body and at both ends of the pump body, lubricated with butter.

The double suction sealing ring is used to reduce water leakage from the pump pressure chamber back to the suction chamber.

The double suction centrifugal pump is directly driven by an electric motor through an elastic coupling, and can also be driven by an internal combustion engine if necessary.

The shaft seal is a soft packing seal (mechanical seal structure can be used according to user needs).
