Product Description

The WQ series submersible sewage pump is a beacon of advanced technology, offering remarkable energy-saving capabilities and features such as wrapping-proof and non-clogging design. It supports auto-installation and auto-control and has unparalleled efficacy in draining solid grains and long-fiber debris, setting new standards in sewage management.

Harnessing an innovative impeller design paired with an advanced mechanical seal, this pump excels in transporting liquids containing solids and long fibers. Diverging from traditional designs, its impeller employs a unique single or dual flow-path akin to an elbow, ensuring superior flow-through performance. Complemented by an optimal turbine room design and precise dynamic and static balancing tests, the pump promises stable and reliable operation. Its sophisticated hydraulic system, high efficiency, and adaptable structures and installation modes make it a smart investment that simplifies pump stations while optimizing costs.

The centrifugal pump's impeller is the heart of its operation. Liquid enters the center of the rotating impeller, where sophisticated vanes accelerate it to higher velocities. Centrifugal force expels the liquid into the casing, converting kinetic energy into pressure or head. The type of impeller is crucial, as it directly influences pump performance and efficiency, with various designs tailored for specific applications to maximize operational success.

For the impellers of submersible sewage pumps, we offer a diverse range of options: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type. Each variant is designed to cater to specific operational challenges, providing optimal performance.

The pump's robust copper electric motor, safeguarded by a UL waterproof armored cable, ensures a steady and reliable power supply, even under large flow rate conditions—delivering consistent performance and unmatched durability.

The auto coupling set, also known as a guide rail system, facilitates effortless pump handling within a sump or chamber. This ingenious slide rail assembly permits easy lifting or lowering for maintenance without disconnecting pipes or fittings. The standard kit includes essential components like a base (duckfoot or pedestal), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. Depending on the model, one or two rails guide the pump to its exact seating position or enable easy removal, ensuring seamless operation.
Our guide rail system is enhanced with the following attachments:
High-strength fixing stand
Secure locking arrangement
Durable bend pipe
