Vertical multistage pumps can be classified from multiple angles, mainly including the following main classification methods:
Classification by appearance: The vertical multistage pump is characterized by the vertical installation of the pump body and the motor, which is usually suitable for occasions with limited space or requiring higher head.
Classification by material:
Stainless steel multistage pump: The main part is made of stainless steel, which has high corrosion resistance and is particularly suitable for conveying corrosive media.
Ordinary multistage pump: Suitable for conveying clean water or liquids with physical and chemical properties similar to water.
Classification by function and application:
Centrifugal multistage water pump: The centrifugal force is generated by the rotation of the impeller to transport water from low to high. It is further subdivided into D-type multistage centrifugal pumps, CDL-type vertical multistage centrifugal pumps, etc.
Vertical multistage centrifugal pumps: Through the series operation of multiple impellers, the water undergoes multiple centrifugal accelerations to obtain a higher head, which is widely used in water supply, industrial boosting, liquid transportation, water treatment and irrigation.
Classification by structural form:
Segmented multi-stage centrifugal pump: The pump body consists of the water inlet section, the middle section (including the guide vane), the water outlet section and the tail cover, which is suitable for conveying clean water or liquids with physical and chemical properties similar to water.
