Product Description

The WQ series submersible sewage pump epitomizes cutting-edge technology with its remarkable energy-saving capabilities and exceptional wrapping-proof design. This pump is engineered for non-block operations, featuring auto-installation and control mechanisms. Its unique design excels in handling solid grains and long fiber debris, making it an indispensable asset in efficient drainage operations.

With an innovative impeller structure and a state-of-the-art mechanical seal, this pump is adept at transporting liquids containing solids and fibrous materials. The impeller, available in single or dual flow-path designs, boasts excellent flow-through performance akin to an elbow of the same section. Coupled with a well-designed turbine room, this pump delivers remarkable efficiency and stability, backed by rigorous dynamic and static balancing tests.

Detailed Photos

The impeller, the heart of our centrifugal pump, is masterfully designed to enhance performance. Liquid enters the core of the rotating impeller, where the vanes accelerate it to higher velocities. The centrifugal force propels the liquid into the diffuser, converting kinetic energy into pressure. Our pumps' performance and efficiency are intricately linked to the impeller's design, with various options tailored for specific applications.

For submersible sewage pumps, we offer an array of impeller designs including vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each catering to diverse operational demands.

Our submersible sewage pumps are equipped with a robust copper electric motor and a UL-certified waterproof armored cable, ensuring a stable power supply even for pumps with high flow rates, thereby guaranteeing consistent performance.

The auto coupling set, also known as the guide rail set/system, revolutionizes maintenance by allowing seamless lifting or lowering of pumps within a sump or chamber. This is achieved without detaching fittings, fixings, or pipework. A standard kit includes a base (either 'duckfoot' or 'pedestal'), pump adaptor/guide hook, and upper rail positioning bracket, along with lifting chains and shackles. Depending on the model, one or two rails guide the pump to its seating location or facilitate easy removal.
The guide rail system includes the following attachments:
Fixing stand
Locking arrangement
Bend pipe
