Multi-stage Centrifugal Pump is designed with two or more impellers. The impellers are mounted on the same shaft. The pumped fluid is discharged from an impeller and volute and immediately enters the next impeller and volute. Multi-stage centrifugal pumps use multiple impellers and volutes in series to achieve pressure. If high pressures at the outlet are required, impellers can be connected in series whereas, for high flow output, the pumps are typically connected parallel.

The pump is a horizontal multistage centrifugal pump suitable for conveying clean water (containing less than 1% of impurities, particle size less than 0.1 mm) and other liquids with physicochemical properties similar to clean water. D type pump conveying medium temperature is less than 80 °C, suitable for mine drainage, oilfield water injection, factory and city supply, drainage and other occasions. Oilfield water injection pumps are made of different materials depending on the corrosive nature of the medium. The DG pump has a medium temperature of less than 105 ° C and is suitable for various boiler feed waters.
