Product Description

The WQ series submersible sewage pump is engineered to deliver outstanding energy efficiency, with features that include wrap-resistance, non-blockage, auto-installation, and intelligent auto-control. It excels in draining solid particles and long fiber waste, making it a powerhouse performer in its category.

With its innovative impeller structure and cutting-edge mechanical seal, our WQ series pump efficiently transports liquids containing solids and long fibers. Unlike conventional designs, the pump's impeller offers a single or dual flow-path akin to an elbow of the same section, boasting exceptional flow-through performance. Paired with a well-designed turbine room, this pump exhibits remarkable efficiency. Following dynamic and static balancing tests on the impeller, it operates with unwavering stability and dependability. This series is renowned for its advanced hydraulic performance, superior efficiency, and varied structures and installation modes, streamlining pump stations and reducing investment costs.

Detailed Photos

The impeller, the heart of a centrifugal pump, is a dynamic component that transfers kinetic energy to the liquid. As it rotates, it draws liquid into its center, accelerating it to higher velocities before discharging it into the casing via centrifugal force. The casing's collection chamber efficiently converts this kinetic energy into head or pressure. The type of impeller significantly influences the pump's performance and efficiency, with different designs tailored to diverse applications.

For our submersible sewage pumps, we offer a diverse range of impeller options, including the vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each designed for optimal performance in their specific applications.

Our robust copper electric motor, paired with UL-certified waterproof armored cables, ensures a stable power supply for submersible sewage pumps, supporting high flow rates and delivering exceptional reliability.

The auto coupling set, also known as a guide rail system, revolutionizes maintenance and cleaning. This slide rail assembly allows the pump to be effortlessly lifted or lowered within a sump or chamber without disconnecting fittings or pipework. It includes essential components like a 'duckfoot' or pedestal base, pump adaptor/guide hook, upper rail bracket, lifting chains, and shackles. The pump is guided by one or two rails, depending on the model, ensuring proper seating and easy removal for maintenance.
The guide rail system includes these essential components,
Fixing stand
Locking arrangement
Bend pipe
