Introducing the WQ series submersible sewage pump, meticulously engineered to deliver remarkable energy efficiency, anti-wrapping capabilities, and non-blocking operations. Designed for auto-installation and auto-control, this pump is uniquely effective in draining solid grains and long-fiber debris with ease.
With an innovative impeller structure and cutting-edge mechanical seal, this pump excels at transporting liquids with solids and long fibers. The impeller's single or dual flow-path design, akin to a sectioned elbow, offers extraordinary flow performance. Paired with a well-designed turbine chamber, this pump promises exceptional efficiency and stability. Subjected to dynamic and static balancing tests, the impeller ensures reliable operation, making it a top choice for advanced hydraulic performance.
The impeller, a vital component of centrifugal pumps, directs liquid into its center, where the vanes accelerate it to higher velocities, discharging it through centrifugal force. The casing's collection chamber transforms much of this Kinetic Energy into Head or Pressure. Pump performance and efficiency largely hinge on the impeller type, with various designs available to cater to different applications.
Our submersible sewage pumps offer diverse impeller options, including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, providing tailored solutions for varied needs.
Boasting a robust copper electric motor and UL-certified waterproof armored cable, our submersible sewage pumps ensure a consistent and stable power supply for high flow rate operations.
The auto coupling set, or guide rail system, is an innovative slide rail assembly facilitating easy pump lifting or lowering within a sump or chamber. This eliminates the need to disconnect fittings or pipework during maintenance. The standard kit comprises a 'duckfoot' or pedestal base, pump adaptor/guide hook, and upper rail positioning bracket, along with lifting chains and shackles, ensuring seamless pump positioning or removal.
The guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
