S type single stage double suction centrifugal pump

S-type single-stage double-suction centrifugal pump is a new type of energy-saving horizontal center-opening pump for conveying clean water or other liquids with similar physical and chemical properties to water. According to the needs of users, it can be used to convey mud-sand water or various types by changing the structure and material of the pump. For corrosive liquids, this series of pumps are suitable for factories, mines, urban water supply and drainage, power stations, farmland drainage and irrigation and various water conservancy projects.

Structure description <br /> The suction and discharge ports of this type of pump are both below the pump's shaft centerline and perpendicular to the axis. There is no need to disassemble the inlet and outlet water pipes and motors during maintenance. Looking from the transmission direction, the water pump rotates clockwise (can be changed to rotate counterclockwise according to user needs).
The main parts of the pump are: pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve, etc.
The pump body and the pump cover constitute the working chamber of the impeller. The inlet and outlet flanges are made with pipe screw holes for installing vacuum gauges and pressure gauges. The lower part of the water inlet and outlet flanges are made with pipe screw holes for discharging water.
The impeller after static balance verification is fixed on the shaft by the sleeve and the sleeve nut on both sides, and its axial position can be adjusted by the sleeve nut.
The pump shaft is supported by two single-row radial ball bearings. The bearing is installed in the bearing body, installed at both ends of the pump body, and lubricated with butter.
The double suction seal ring is used to reduce water leakage from the pump pressure water chamber to the water suction chamber.
The pump is directly driven by an electric motor through an elastic coupling, and if necessary, it can also be driven by an internal combustion engine.
The shaft seal is a soft packing seal (mechanical seal structure can be used according to user needs).
