Description

This series of pumps are horizontal single-suction multi-stage segmented centrifugal pumps, using hydraulic models of high-efficiency energy-saving products

recommended by the country. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long life, and convenient

installation and maintenance.It can be used to transport clear water without solid particles (abrasive), no suspended matter or other liquids with physical and

chemical properties similar to clear water.

It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump (or the material of the pump flow part),

sealing form and adding a cooling system.
