Product Description

Introducing the WQ series submersible sewage pump, celebrated for its remarkable energy-saving capabilities, anti-wrapping technology, non-blocking design, and features like auto-installation and auto-control. This pump is uniquely effective in draining solid particles and long fibrous waste with unparalleled precision.

Equipped with an innovative impeller structure and a pioneering mechanical seal, this pump adeptly handles liquids containing solids and long fibers. Unlike traditional impellers, it adopts a single or dual flow-path design akin to an elbow, delivering exceptional flow-through performance. Complemented by a well-designed turbine room, this pump assures outstanding operational efficiency. The impeller undergoes dynamic and static balancing tests for stable, reliable performance. Our advanced hydraulic system enhances efficiency while offering versatile structures and installation options, optimizing pump stations and reducing investment costs.

Detailed Photos

In the realm of centrifugal pumps, the impeller is pivotal. As liquid enters the center of the rotating impeller, it's captured by the vanes, accelerated, and discharged at high velocity by centrifugal force into the diffuser casing. This collection chamber transforms much of the kinetic energy into hydraulic head or pressure. The choice of impeller type profoundly impacts pump performance and efficiency, with various designs tailored for specific applications.

Our submersible sewage pumps offer a variety of impeller options: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, catering to diverse operational needs.

The robust copper electric motor, paired with UL-certified waterproof armored cables, assures a stable and reliable power supply for our high-flow submersible sewage pumps.

The auto coupling set, or guide rail system, facilitates seamless pump management within a sump or chamber. This slide rail assembly allows effortless lifting or lowering of the pump for maintenance, eliminating the need for disconnection of fittings or pipework. Standard kits include a base (duckfoot or pedestal), pump adaptor/guide hook, upper rail positioning bracket, lifting chains, and shackles. The system guides the pump via one or two rails (not included), ensuring precise seating with a secure seal or enabling easy removal.
The guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
