Product Description

The WQ series submersible sewage pump is engineered for excellence, showcasing features like exceptional energy-saving capabilities, anti-wrapping design, and blockage prevention. Its auto-installation and auto-control functionalities make it ideal for managing solid grains and long fiber debris with remarkable efficiency.

This innovative pump boasts a unique impeller structure and a cutting-edge mechanical seal that facilitate the efficient transport of liquids containing solids and long fibers. Unlike conventional impellers, our pump's impeller employs a single or dual flow-path design, akin to an elbow with superior flow-through performance. Coupled with a meticulously designed turbine room and subjected to dynamic and static balancing tests, this pump operates with extraordinary stability and reliability. Its advanced hydraulic performance, high efficiency, and diverse structural and installation modes simplify pump station operations, optimizing investment costs.

Detailed Photos

The impeller, a critical component of a centrifugal pump, is responsible for propelling liquids into higher velocities. As liquid enters the center of the rotating impeller, it is pushed outward by the impeller's vanes, gaining speed and being discharged through centrifugal force into the case (diffuser). The casing's collection chamber then converts much of the kinetic energy into head or pressure. The impeller's design is pivotal to pump performance and efficiency, with different variations crafted to cater to specific applications.

In our submersible sewage pumps, we offer an array of impeller options, including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each tailored to specific needs.

Our robust copper electric motor, paired with a UL waterproof armored cable, ensures a consistent and stable power supply, particularly for submersible sewage pumps with large flow rates.

The auto coupling set, or guide rail system, revolutionizes pump maintenance by allowing easy pump removal or repositioning within a sump or chamber without disconnecting any fittings or pipework. The standard kit includes a base (duckfoot or pedestal), pump adaptor/guide hook, upper rail positioning bracket, lifting chains, and shackles. Depending on the model, the pump is maneuvered by one or two rails, ensuring precise seating with a positive seal or facilitating effortless removal from the system.
Guide rail system come with the following attachment,
Fixing stand
Locking arrangement
Bend pipe
