Product Description

Introducing the WQ series submersible sewage pump, a marvel of engineering that boasts remarkable energy-saving capabilities, exceptional anti-wrapping features, and a non-blocking design. This pump is equipped with auto-installation and auto-control functionalities, making it uniquely adept at efficiently handling solid grains and long fiber waste.

Utilizing an innovative impeller structure and a cutting-edge mechanical seal, this pump excels in transporting liquids containing solids and long fibers. The impeller's design, featuring a single or dual flow-path similar to an elbow, offers exceptional flow-through performance. Coupled with a precisely engineered turbine room, the pump delivers outstanding efficiency. With dynamic and static balancing tests conducted on the impeller, the pump ensures stable and reliable operation. This series offers advanced hydraulic performance, various structures, and installation options, streamlining the pump station and optimizing investment.

Detailed Photos

The impeller, the heart of a centrifugal pump, plays a pivotal role. As liquid enters the center of the rotating impeller, it is accelerated by the vanes and propelled into the casing (diffuser) by centrifugal force. This process converts kinetic energy into pressure, central to pump performance and efficiency. Various impeller designs have been developed to cater to diverse applications, enhancing the pump's adaptability.

For our submersible sewage pumps, we offer a range of impeller options: the vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each tailored to specific requirements.

Our submersible sewage pumps feature a robust copper electric motor and UL-approved waterproof armored cable, ensuring a stable and reliable power supply for high flow rate operations.

The auto coupling set, also known as the guide rail set/system, is an ingenious slide rail assembly. This system allows for easy lifting or lowering of the pump within a sump or chamber for maintenance or cleaning, negating the need to disconnect any fittings or pipes. The standard kit comprises a base ('duckfoot' or 'pedestal'), a pump adaptor/guide hook, and an upper rail positioning bracket, complete with lifting chains and shackles. Depending on the model, the pump is guided by one or two rails, directing it to the correct seating for a positive seal or easy removal from the system/sump.
The guide rail system comes equipped with the following attachments:
Fixing stand
Locking arrangement
Bend pipe
