The DG series pump is horizontal multistage centrifugal pump, with the features of high efficiency, wide performance 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 DG series multistage centrifugal pumps are specially design for hot water projects, it is also named as boiler feed pump. This series of multistage pumps are widely used in high pressure water transferring projects like boiler feeding, heating network boosting, industrial water supply, high building water supply, mining water discharge, long distance water transferring, power plant, salty industry and sea water desalination, etc.
