Product Description

The WQ series of submersible sewage pumps are engineered to deliver remarkable energy efficiency, robust anti-wrapping features, and non-blocking capabilities. These pumps offer seamless auto-installation and control, uniquely excelling in the efficient drainage of solid particles and long fiber debris.

Employing a unique impeller design alongside a state-of-the-art mechanical seal, this pump excels in transporting liquids containing solids and long fibers. In comparison to conventional impellers, our design utilizes a single or dual flow-path, akin to a well-crafted elbow of the same cross-section. This design ensures superior flow-through performance. Coupled with an optimized turbine room, this pump operates with outstanding efficiency. Dynamic and static balancing tests of the impeller guarantee stable and reliable operation. The series boasts advanced hydraulic performance, superior efficiency, and diverse structural and installation configurations, simplifying pump station design and reducing investment costs.

Detailed Photos

The impeller serves as the pivotal rotating component of a centrifugal pump. As liquid enters the center of this spinning marvel, it is swiftly caught by the vanes and accelerated to higher velocities through centrifugal force before being discharged into the casing (diffuser). This process transforms much of the kinetic energy of velocity into valuable head or pressure. Pump performance and efficiency are largely determined by the impeller type, with various designs tailored to specific applications.

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

A robust copper electric motor paired with a UL-certified waterproof armored cable ensures a steady and reliable power supply, even for submersible sewage pumps with high flow rates.

An auto coupling set, or guide rail system, simplifies maintenance and cleaning tasks by allowing easy lifting or lowering of the pump in a sump or chamber without disconnecting fittings or pipework. This assembly includes a base ('duckfoot' or pedestal), pump adaptor/guide hook, and upper rail positioning bracket, along with lifting chains and shackles. Depending on the model, the pump is guided by one or two rails, ensuring proper seating with a positive seal or facilitating easy removal.
Guide rail system come with the following attachment,
Fixing stand
Locking arrangement
Bend pipe
