WQD submersible sewage pumps equip single phase asynchronous motor. Double mechanical seal is used between water pump and motor, and O-ring is applied among all the static joints. Electrostatic painting was used on surface to make the pump wear-resistant, anti-corrosive and anti-rusty. The impeller of the pump is semi-open type or closed. The typical applications are industry, agriculture, bulding operations and environmental protection, to be allowed to pump mud, mortar, waste water and sewage such as solid granules short fiber, wstepaper and mud as well as sand, farm drainage and irrigation, river and pond dredging.
