WQ Series Submersible Sewage Pumps hold a comprehensive optimized design on its hydraulic model, mechanical structure, sealing, and motor cooling and protection. We offer three types of impellers to guarantee non-clogging ability and long service life: double-channel impeller for liquid containing solid particles and short fibers; open impeller for sewage containing long fibers; closed impeller for high lifting working condition; stainless impeller for light corrosive liquid. Besides good performance, we have advanced machining equipment and assembly lines to enhance productivity and lower the cost of the pump.
 

• Our innovative overload-free hydraulic design allows for a wide operating range, high efficiency, minimal vibration, and smooth operation. It also ensures the passage of solid materials and resistance to fiber entanglement.

• The excellent dual end-face in-line installed mechanical seals and self-cleaning lower water seal function on the pump cover guarantee a lifespan of both seals exceeding 15,000 hours.

• The high reliability submersible motor is rated at H-class insulation, with a maximum operating temperature of 180°C.

• Pump body, pump cover, and oil chamber castings undergo electrophoretic treatment or paint coating to enhance corrosion resistance.

• The overall structure ofct the impeller mounting shaft, ensures reliable operation with the pump center positioned low.
