The WQ series submersible sewage pump is engineered with advanced features such as notable energy-saving effects, wrapping-proof construction, non-blocking capabilities, auto-installation, and auto-control. It excels in efficiently draining solid grains and long-fiber debris, redefining the standard for sewage management.
Our innovative impeller design and state-of-the-art mechanical seal enable this pump to transport liquids containing solids and long fibers with ease. The impeller's single or dual flow-path design, akin to an elbow of similar section, ensures excellent flow-through performance. Supported by a well-designed turbine room, the pump operates with outstanding efficiency. Rigorous dynamic and static balancing tests make it a model of stability and reliability. This series boasts advanced hydraulic performance, superior efficiency, and multiple structure and installation options, simplifying pump station setup and reducing investment costs.
The impeller, a pivotal component of a centrifugal pump, significantly influences performance and efficiency. Liquid enters the center of the rotating impeller, where it is accelerated and discharged by centrifugal force into the casing. The casing converts kinetic energy into head or pressure. Various impeller designs cater to diverse applications, enhancing pump functionality and adaptability.
For submersible sewage pumps, we offer a selection of impellers: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, providing tailored solutions for distinct requirements.
Featuring a robust copper electric motor and UL water-proof armored cable, our submersible sewage pump guarantees a consistent and stable power supply, ensuring high flow rates and reliable operation.
Our auto coupling set, or guide rail system, revolutionizes maintenance with its slide rail assembly. This system allows hassle-free lifting or lowering of the pump for cleaning or maintenance without disconnecting fittings or pipework. A typical kit includes a base (duckfoot or pedestal), pump adaptor/guide hook, and upper rail positioning bracket, complete with lifting chains and shackles. Selected models guide the pump via one or two rails for accurate seating or easy removal.
Guide rail system come with the following attachment,
Fixing stand
Locking arrangement
Bend pipe
