Horizontal split pump can also be called as horizontal single-stage double suction centrifugal pump/horizontal split double suction pump, which is mainly used to transport muddy water or various corrosive liquids. This series of pumps are applicable to factories, mines, urban water supply and drainage, power stations, farmland irrigation and drainage and various water conservancy projects. S and SH single-stage double suction pipeline centrifugal pumps are used to transport clean water or other liquids with physical and chemical properties similar to water. According to user needs, the pump structure and material can be changed.


1. The allowable working pressure is 2.5Mpa; That is, pump inlet pressure+pump lift 2.5Mpa.

2. Medium: clean water with temperature 105 or other liquids with physical and chemical properties similar to clean water (solid particles 80mg/L).

3. The sealed rolling bearing with grease lubrication is easy to maintain and has a long running time.

4. The oil cup with constant oil level can also be lubricated with thin oil. According to the maximum pressure borne by the pump casing, the pump body and pump cover are made of gray cast (1.6Mpa).

Imported high quality bearings are selected to ensure smooth operation, low bath noise and long service life. Stainless steel centrifugal pump has compact structure and good stability. This series of pumps are of split casing structure, and the inlet and outlet are on the pump body. During maintenance, just lift out the pump cover, and the rotor parts can be moved out for maintenance without dismantling the pipeline, which is very convenient. The motor (driver) can be at the left end or the right end as required, which is convenient for on-site installation. In structure, the axial dimension of rotor components is shortened, and the shaft has better rigidity and more stable and reliable operation. The pump body seal ring is provided, and the impeller seal ring is optional. The seal ring can be replaced after wear, reducing the operation and maintenance costs.
