Product Description

Introducing the WQ series submersible sewage pump, renowned for its significant energy-saving capabilities, exceptional wrapping-proof and non-blocking properties, as well as its auto-installation and auto-control features. This pump is uniquely effective in draining solid grains and long-fiber debris, ensuring optimal functionality in various demanding environments.

Equipped with a unique impeller design and an innovative mechanical seal, this pump excels in transporting liquids laden with solids and long fibers. Unlike traditional impellers, this model features a single or dual flow-path, akin to an elbow of the same section, offering exceptional flow-through performance. This is complemented by a finely tuned turbine room, allowing the pump to operate with heightened efficiency. Subjected to rigorous dynamic and static balancing tests, the impeller ensures stable and reliable operation. This series boasts advanced hydraulic performance, high efficiency, and versatile structural and installation modes, significantly simplifying pump station management and reducing investment costs.

Detailed Photos

The impeller, the heart of the centrifugal pump, is a marvel of engineering. As it rotates, liquid enters at the core and is propelled by the vanes, gaining velocity through the centrifugal force to be discharged into the casing. This kinetic energy is then transformed into head or pressure within the collection chamber. The type of impeller critically determines the pump's performance and efficiency, with various designs crafted to meet diverse application needs.

Our submersible sewage pumps offer a variety of impeller designs tailored for specific uses, including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with an integrated cutter for enhanced functionality.

The robust copper electric motor, paired with a UL-certified waterproof armored cable, guarantees a reliable power supply, ensuring the submersible sewage pump delivers a high flow rate with steadfast stability.

The auto coupling set, also known as a guide rail system, facilitates effortless pump maintenance. This slide rail assembly allows easy lifting or lowering within a sump or chamber, eliminating the need to disconnect fittings, fixings, or pipework. A standard kit includes a base ('duckfoot' or 'pedestal'), a pump adaptor/guide hook, and an upper rail positioning bracket, complete with lifting chains and shackles. Depending on the model, the pump is steered up and down by one or two rails, not included, ensuring precise seating or simple removal from the system.
Our guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
