D, DG Series Multistage Water Pump

Send Message Request a Quote

The D, DG series multistage water pump can be split into different sections. Usually operating in a horizontal position, the pump allows clean water or fluids with chemical and physical properties similar to those of water to enter the pump from only one side.

The D series water pump can transport media with temperatures no more than 80℃. It is primarily used to get rid of accumulated water from mines, and supply water to factories and cities.

The DG series can operate properly at a high temperature of 105℃. Hence, it is suitable for feeding water to the boiler.
