4″ WQ Submersible Dirty Water Pump With Water Proof Motor ISO 9001

4″ SS304 Sewage Drainage Non-Clogging Industrial Submersible Water Pump High Efficiency ISO 9001

Proper medium: liquids with chemical property similar to pure water should be non-corrosive. Solid size should be no larger than 30% of the pump suction diameter. Fiber length should not be over 2.5 times of the pump suction diameter. When the medium density is more than 1.05, the motor power should be increased accordingly to prevent the motor from overload operation.

China WQ(D)S Stainless Steel Submersible Sewage Pump

WQ(D)S stainless steel submersible sewage pump has a stainless steel motor case for beauty and endurability.

Open impeller is designed for easier passage of suspended solid.

The stainless steel shaft extension, carbide double sides mechanical sealing has a great sealing feature.

The float switch automatically controls the pump to stop according to the required water level change.

The motor can adopt a water jacket type external circulation cooling system to ensure the safe operation of the electric pump in the waterless (dry) state.

The double-rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump.

Optional Available on Request
