Product Description

The WQ series submersible sewage pump is a marvel of engineering, featuring remarkable energy-saving capabilities, anti-wrapping technology, non-clogging design, and automated installation and control. It is uniquely efficient in handling solid grains and long-fiber waste, making it an indispensable solution for challenging drainage applications.

This pump, with its innovative impeller structure and cutting-edge mechanical seal, excels at transporting liquids laden with solids and long fibers. The impeller’s single or dual flow-path design, akin to an elbow of matching section, ensures superior flow-through performance. Paired with a well-designed turbine room, this pump operates with impressive effectiveness. Its impeller undergoes rigorous dynamic and static balancing tests, ensuring stability and reliability. The series boasts advanced hydraulic performance, high efficiency, and a variety of structural and installation configurations, which streamline pump stations and reduce investment costs.

Detailed Photos

The impeller, the heart of a centrifugal pump, is key to its operation. As liquid enters the center of the spinning impeller, it is accelerated by the vanes to a higher velocity and discharged by centrifugal force into the casing. The casing’s collection chamber transforms much of this kinetic energy into pressure, enhancing pump performance and efficiency. Various impeller designs are available to meet diverse application needs.

For our submersible sewage pumps, a range of impellers is offered: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, catering to various operational requirements.

Our submersible sewage pumps are powered by a robust copper electric motor and equipped with UL waterproof armored cable, providing a stable and reliable power supply for high flow rate operations.

The auto coupling set, also known as a guide rail system, facilitates the effortless lifting or lowering of pumps within a sump or chamber for maintenance without disconnecting fittings or pipework. A standard kit includes a base ('duckfoot' or 'pedestal'), a pump adaptor/guide hook, and an upper rail positioning bracket, along with lifting chains and shackles. Depending on the chosen model, one or two rails—though not included—guide the pump to its proper seating or enable easy removal from the system.
Guide rail system comes with the following attachments:
Fixing stand
Locking arrangement
Bend pipe
