Our comprehensive product line includes a robust range of water submersible pumps, sewage effluent sump pumps, and drainage pumps, all designed for efficient wastewater removal, proudly showcasing our commitment to excellence.
Our wastewater solutions, epitomized by our superior Drainage and Sewage Pumps, are a testament to decades of unrivaled expertise. These solutions shine in performance and reliability while offering cost efficiency and serviceability, ensuring an optimal balance between quality and affordability.

Product Description

The WQ series submersible sewage pump is engineered to deliver outstanding energy efficiency, featuring anti-wrapping, non-blocking capabilities, and seamless auto-installation and control. Its design is especially effective in draining solid particles and long fiber waste, ensuring uninterrupted operation.

Thanks to a revolutionary impeller structure paired with a cutting-edge mechanical seal, our pump can seamlessly transport liquids containing solids and long fibers. Unlike conventional models, our impeller's single or dual flow-path design mimics an elbow, providing superior flow-through performance. Fitted with a meticulously crafted turbine room, the pump achieves remarkable efficiency. Post dynamic and static balancing tests, it operates with unmatched stability and reliability, while its advanced hydraulic performance and versatile structure simplify pump station setup, reducing overall investment.

Detailed Photos

In a centrifugal pump, the impeller is the pivotal rotating component. It accelerates liquid entering at its center via its vanes, discharging it by centrifugal force into the casing, where kinetic energy is transformed into pressure. The type of impeller dictates pump efficiency and performance, with various designs tailored to specific applications.

For submersible sewage pumps, we offer multiple impeller options: vortex type, semi-open channel type, non-clog closed type, and non-clog impeller with cutter type, each adaptable to varying needs.

Our submersible sewage pumps feature a robust copper electric motor and UL water-proof armored cable, guaranteeing a stable power supply, even for high flow rate capacities.

An auto coupling set, also known as a guide rail system, includes a slide rail assembly for effortless pump raising and lowering in a sump or chamber. This setup facilitates cleaning and maintenance without detaching connections or pipes. Standard kits feature a base ('duckfoot' or 'pedestal'), a pump adaptor/guide hook, and an upper rail positioning bracket, along with lifting chains and shackles. Models vary in configuration, using one or two rails to guide the pump for secure placement or easy removal.
Our guide rail systems include these comprehensive attachments:
Fixing stand
Locking arrangement
Bend pipe
