Features of the split centrifugal pump: The split centrifugal pumps S, S1, SM, SF, SY series are double suction single-stage centrifugal pumps, which are designed in accordance with national standards and specifications. They are highly serialized, standardized, and generalized, and can be used for the transmission of multiple media. They are more widely used than SA and SH, such as industrial, urban water supply and drainage, farmland irrigation, water intake, pressurization, and petrochemical projects of various water conservancy projects, power stations, and industrial process systems. With regard to the performance parameters and overall installation dimensions of the split centrifugal pumps S1, SM, SF, SY series are the same as those of the S-type pumps, Shenyi Water Pump describes the differences between them as follows:

1. S-type pump is used to transport clear water or liquid with physical and chemical properties similar to water, and the shaft seal type is packing seal; The material of overflow part is ordinary cast iron

2. S1 type pump is used to transport clean water or liquids with physical and chemical properties similar to water. The shaft seal type can be packed or mechanically sealed according to the user's requirements. It is an improved design based on the S-type pump. The material of the overflow part is ordinary cast iron

3. SM type pump is a new product designed on the basis of S1 type pump, which is based on the characteristics of sediment rivers and similar water quality and adopts new anti-wear structure and material, and is used for transportation of muddy sand media; The type of shaft seal can be packed or mechanically sealed according to the user's requirements; The material of the overflow part is wear-resistant cast iron, etc

4. SF type pump is a new product designed with corrosion-resistant materials and mechanical seal structure on the basis of S1 type pump, which is used for transportation of various corrosive media and oil products;

5. SY pump is improved and designed on the basis of S1 pump. It is used for the transportation of various oil products and can be made of various materials. The shaft seal is a mechanical seal.
