Product Description

Introducing the WQ series submersible sewage pump, a marvel of engineering that showcases significant energy-saving effects, wrap-proof design, and non-blocking capabilities. With auto-installation and auto-control features, this pump excels in draining solid grains and long fiber waste effectively, offering unparalleled efficiency in sewage and slurry management.

Our pump employs a revolutionary impeller structure and a state-of-the-art mechanical seal, adept at transporting liquids containing solids and long fibers with ease. Unlike conventional impellers, this design features a single or dual flow-path architecture, akin to an elbow of the same section, ensuring exceptional flow-through performance. Coupled with a sophisticated turbine room and having passed dynamic and static balancing tests, this pump promises stable and reliable operation. Its advanced hydraulic performance, high efficiency, and versatile installation modes simplify pump station operations and reduce investment costs.

Detailed Photos

The impeller, a pivotal component of centrifugal pumps, captures liquid directed into its center via vanes, accelerating it to higher velocities. Through centrifugal force, the liquid is then discharged into a diffuser. The casing's collection chamber ingeniously converts kinetic energy into head or pressure. The impeller's design is crucial to pump performance and efficiency, with various tailored designs available to suit specific applications.

Our selection of impellers for submersible sewage pumps includes vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, catering to diverse operational needs.

Equipped with a robust copper electric motor and a UL water-proof armored cable, our submersible sewage pump guarantees a stable power supply, perfectly suited for handling large flow rates with reliability and efficiency.

The auto coupling set, synonymous with the guide rail system, is a precision slide rail assembly that allows effortless lifting or lowering of the pump within a sump or chamber. This system facilitates cleaning or maintenance without disconnecting fittings or pipework. A standard kit includes a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, and upper rail positioning bracket, complemented with lifting chains and shackles. Depending on the model, the pump is guided by one or two rails, directing it to its seating location with a positive seal for easy removal.
The guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
