Experience the pinnacle of technological innovation with our products, designed to optimize wastewater management.
The WQ series submersible sewage pump is a marvel of engineering, featuring significant energy-saving capabilities, wrap-proof design, non-block technology, and automatic installation and control. Uniquely proficient in the drainage of solid grains and long fiber waste, this pump delivers optimal performance for demanding environments.
With an innovative impeller structure and state-of-the-art mechanical seal, our pump excels in transporting liquids embedded with solids and long fibers. Its advanced impeller design, offering a single or dual flow-path akin to an elbow, ensures excellent flow-through performance. Coupled with a finely tuned turbine room, this pump achieves remarkable efficiency and stability. The dynamic and static balancing test on the impeller guarantees reliable operation, making it a top choice for efficient pump station management and investment savings.
The impeller serves as the dynamic heart of a centrifugal pump. Liquid introduced into the center is captured by the vanes, gaining velocity through rotation before being propelled by centrifugal force into the casing. Here, kinetic energy transforms into pressure, defining the pump's performance and efficiency. Diverse impeller variations are engineered to match specific application needs, ensuring peak productivity.
Our range of submersible sewage pump impellers includes vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, offering versatile solutions tailored to diverse application demands.
Equipped with a rugged copper electric motor and UL-certified water-proof armored cable, our submersible sewage pump ensures a stable and powerful supply, perfectly suited for high flow rate applications.
The auto coupling set, or guide rail system, is ingeniously designed to facilitate effortless pump maintenance. This slide rail assembly allows the pump to be easily lifted or lowered without disconnecting any fittings, fixings, or pipework. A standard kit comprises a base ('duckfoot' or 'pedestal'), pump adaptor/guide hook, upper rail positioning bracket, lifting chains, and shackles. Depending on your model selection, one or two guide rails (not included) ensure precise seating alignment and simplify pump removal.
The guide rail system is accompanied by the following attachments,
Fixing stand
Locking arrangement
Bend pipe
