The DPG series pump is horizontal multistage section centrifugal pump, with the unique design of "self balancing - back to back arranged impellers on the same shaft", which could relief the axial thrust force occurring during the operation of the pump without requiring a separate balancing parts (balance disc, balance plate, balance ring). It have the features of high efficiency, wide flow & head range, stable performance, easy maintenance and long service life.

The multistage design compress the water stage by stage and reaching the high pressure to meet the delivery head site required. It is widely used to deliver the clean water, sewage water, corrosive liquid, hot water, seal water and oil liquid by selecting different mater of flow passage parts.

The DPG multistage pumps are widely applied to high pressure projects like boiler feeding, heating network boosting, industrial water supply, high building water supply, mining water discharge, long distance water transferring, power & heating plant, salty industry and sea water desalination, etc.
