Sh type centrifugal pumps are used to transport clean liquids that do not contain solid particles and whose temperature does not exceed 80°C.
Sh type pump body adopts horizontal split type, with single-stage and double-suction impeller, suction and discharge pipes are cast together with the lower part of the pump body, and the rotor parts of the pump can be easily inspected without disassembling the pipeline and the motor.
The pump is sealed with soft packing, and a replaceable shaft sleeve is installed at the shaft seal.
The pump is driven by an electric motor through a flexible coupling. From the driving end, the pump rotates counterclockwise (clockwise rotating pumps can be supplied according to special orders).
Bearing and balancing device:
Bearing bodies (rolling bearings or sliding bearings) are installed on both ends of the pump shaft. The axial force is balanced by the double-suction impeller, and the residual axial force is balanced by the rolling bearing. The rolling bearings are lubricated with grease, and the sliding bearings are lubricated with thin oil.

Seal ring…………Cast iron; Shaft……………High-quality carbon steel
Impeller……………cast iron, cast steel
This type of pump is equipped with a common base when the power of the matching motor is below 110kW. If a common base is required for more than 100kW, it must be stated when ordering. If the motor supporting the pump has special requirements, it is also put forward when ordering.
The material and model of the pump are also different according to the conveying medium:
1. The clean fluid without solid particles, the models are Sh, ShG, ShT, of which the Sh type is all made of cast copper, and the pump body is made of cast iron.
2. Corrosive media such as sea water, the models are ShN, ShF, the material of the ShN pump body is nickel cast iron, and the material of the ShF pump body is stainless steel.
