Product Description

The WQ series submersible sewage pump is engineered to deliver outstanding energy efficiency with features such as wrap-proof design, non-block technology, auto-installation, and auto-control functionality. It excels in the effective drainage of solid particles and long-fiber waste, ensuring seamless operations.

Featuring a pioneering impeller structure and modern mechanical seal, this pump excels in transporting liquids containing solids and long fibers. Its advanced design, akin to a single or dual flow-path elbow, offers remarkable flow-through performance. Coupled with a strategically engineered turbine room, this pump ensures stability, reliability, and superior efficiency. The meticulously tested impeller guarantees smooth operation, while diverse installation modes simplify pump stations and optimize investment.

Detailed Photos

At the heart of a centrifugal pump lies the impeller, the dynamic rotating component. As liquid enters the impeller's core, it's swiftly propelled by the vanes, gaining velocity and expelled by centrifugal force into the case (diffuser). The casing's collection chamber expertly converts kinetic energy into head or pressure. The impeller's design is pivotal to pump performance and efficiency, with variations crafted for an array of applications.

For submersible sewage pumps, we offer a selection of impeller types: vortex, semi-open channel, non-clog closed, and non-clog with cutter, each tailored for specific needs.

Equipped with a robust copper electric motor and UL-certified waterproof armored cable, our submersible sewage pumps deliver consistent power for high flow rates, ensuring reliability and durability.

The auto coupling set, also known as a guide rail system, facilitates effortless pump maintenance. This slide rail assembly allows easy lifting or lowering of the pump in a sump or chamber without disconnecting fittings or pipework. A typical kit includes a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. The pump glides along one or two guide rails, ensuring precision seating and easy removal.
The guide rail system is equipped with the following attachments:
Fixing stand
Locking arrangement
Bend pipe
