Product Description

Introducing the WQ series submersible sewage pump, renowned for its remarkable energy-saving capabilities and innovative features: wrapping-proof design, non-blocking efficiency, auto-installation, and seamless auto-control. It is uniquely effective in draining solid grains and long-fiber waste, making it an indispensable tool in sewage management.

Through the adoption of a uniquely designed impeller structure and an avant-garde mechanical seal, this pump efficiently transports liquids containing solids and long fibers. Its impeller, featuring a single or dual flow-path akin to a same-section elbow, offers exceptional flow-through performance. This is complemented by a well-engineered turbine room, ensuring high efficiency and stable, reliable operation. The dynamic and static balancing tests further enhance its operational stability, making it a sophisticated solution with advanced hydraulic performance, multiple structure options, and installation modes that streamline pump station operations and reduce investment costs.

Detailed Photos

The impeller, the dynamic heart of a centrifugal pump, draws in liquid at the center and propels it along its vanes, accelerating it to higher velocities. This process utilizes centrifugal force to discharge the liquid into the casing (diffuser), where the kinetic energy (velocity-based energy) is converted into pressure or head. The efficiency and performance of the pump significantly depend on the impeller type, with numerous variations crafted to meet diverse application requirements.

For submersible sewage pumps, we offer a range of impeller options: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with an integrated cutter, catering to various needs and ensuring efficient operation.

Engineered for robustness, our submersible sewage pumps are powered by a durable copper electric motor and protected by a UL water-proof armored cable, guaranteeing a stable power supply even for high-flow rate applications.

The auto coupling set, commonly referred to as a guide rail set/system, is a sophisticated slide rail assembly designed for effortless pump lifting or lowering within a sump or chamber. This system facilitates cleaning or maintenance without disconnecting fittings, fixings, or pipe work. The standard kit includes a base ('duckfoot' or 'pedestal'), a pump adaptor/guide hook, an upper rail positioning bracket, and lifting chains with shackles. Depending on the selected model, the pump is guided along one or two rails (not included) to its proper seating location with a positive seal or can be easily removed from the system/sump.
Our guide rail system includes the following essential attachments:
Fixing stand
Locking arrangement
Bend pipe
