Product Description

Discover the advanced WQ series submersible sewage pump, engineered with remarkable energy-saving capabilities. This pump boasts an exceptional wrapping-proof, non-block design, alongside features of auto-installation and auto-control. It is uniquely effective in handling the drainage of solid grains and long-fiber waste materials.

This pump employs a revolutionary impeller structure coupled with a new-style mechanical seal, enabling it to efficiently transport liquids containing solids and long fibers. Unlike conventional impellers, this pump's impeller features a single or dual flow-path design akin to an elbow of matching section, offering outstanding flow-through performance. With a meticulously designed turbine room, the pump operates with pronounced efficacy and stability, attested by dynamic and static balancing tests on the impeller. Its advanced hydraulic performance and high efficiency, alongside multiple structural and installation configurations, streamline pump station operations and optimize investments.

Detailed Photos

In the heart of our centrifugal pump lies the impeller—a pivotal rotating component. As liquid enters the impeller's center, the vanes propel it to higher velocities. The centrifugal force then expels the liquid into the casing, converting kinetic energy into pressure. The impeller's design is crucial for pump performance and efficiency, with various adaptations available to meet specific application demands.

Our submersible sewage pumps come with an array of impeller options to suit diverse needs: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type.

Equipped with a durable copper electric motor and UL-certified waterproof armored cable, our submersible sewage pump ensures a consistent and robust power supply, supporting substantial flow rates seamlessly.

The auto coupling set, or guide rail system, revolutionizes maintenance and installation. This slide rail assembly facilitates effortless lifting or lowering of pumps within sumps or chambers, eliminating the need for disconnecting fittings or pipework. Each standard kit contains a base (either 'duckfoot' or 'pedestal'), a pump adapter/guide hook, and an upper rail positioning bracket, complete with lifting chains and shackles. Depending on the selected model, one or two guiding rails, not included, guide the pump to its precise seating, ensuring a positive seal or enabling straightforward removal.
Our guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
