WQS electric non-clog submersible wastewater pump

WQS series submersible wastewater pump is a single stage water-filled submersible pump. It is a subcategory of our WQ submersible sewage pumps, prepared with common features of its kind. The unique feature of WQS is large flow quantity. It is suitable to be used to deliver large amount of wastewater from toilets, sinks, basements. It is ideal equipment for a pumping waste system. Except for common qualities of WQ submersible sewage pumps, WQS features large flow quantity.

Product features of WQS submersible wastewater pump

1. Double suction

WQS series submersible waste water pumps have double-suction water inlet and double-channel impeller. When the submersible waste water pump runs, waste water flows into it from both ends of the impeller, and flow out from the middle of the impeller. This makes the wastewater pumps have large capacity or flow quantity. This series of submersible wastewater pumps is a smart combination of submersible motor and double-suction pump. It not only has the function of submersible pumps but also work stably with high efficiency in the way same as double-suction submersible wasterwater pumps.

2. High efficiency

This pump for wastewater takes water in from bottom. The water then moves into the spiral case, where its kinetic energy is increased under the effect of rotating double-channel centrifugal impeller. Finally it runs out through outlet at one side of the waste water pump. This simple structure makes the wastewater submersible pump small in size, easy to move and install. Together with appropriate volute, this structure helps to balance and reduce the axial force imposed on motor, prolonging the service life of the waste water pump by 3 times, increasing its efficiency by 15%.

3. Non-clog

Today, many factories are trying to use less water for the production of same amount of industrial products. As a result, the waste water from factories would contain more scrap materials. This would increase the cost for waste water treatment, since it is easier to block the waste water submersible pump and pipeline. Besides, a lot of submersible wastewater pump manufacturers pay so much attention to energy-saving that they didn’t pay enough attention to the problem of clogging. Considering about that phenomenon, we had focused our attention on anti-clogging since we began to develop submersible sewage pumps in 2010. The double-channel impeller of WQS series has spiral flow blades, which would effectively prevent clogging.
