Product Description

Introducing the WQ series submersible sewage pump, a marvel of engineering renowned for its significant energy-saving capabilities, anti-wrapping design, non-blocking operation, and automatic installation and control features. This pump excels in the efficient drainage of solid particles and long fiber debris, making it an indispensable tool for waste management.

The pump’s groundbreaking design incorporates a unique impeller structure and a state-of-the-art mechanical seal, allowing it to expertly handle liquids containing solids and long fibers. Unlike traditional impeller designs, this pump utilizes a single or dual flow-path configuration, similar to an elbow, optimizing flow-through performance. Coupled with a precise turbine room, the pump guarantees superior efficiency and stable, reliable operation, thanks to rigorous dynamic and static balancing tests. This series of pumps boasts advanced hydraulic performance, high efficiency, and versatile structures and installation options, simplifying pump stations and reducing investment costs.

Detailed Photos

At the heart of a centrifugal pump lies the impeller, its rotating component. As liquid enters the center of the spinning impeller, it is channeled by the vanes, rapidly gaining velocity before being propelled outward by centrifugal force. This energy is then transformed into pressure within the casing's collection chamber. The impeller's design is critical to optimizing pump performance and efficiency, with various configurations tailored for specialized applications.

Our submersible sewage pumps offer a diverse array of impellers, including vortex type, semi-open channel type, non-clog closed type, and innovative non-clog impeller with cutter type, each designed to meet specific application needs.

A robust copper electric motor paired with a UL-certified waterproof armored cable ensures a stable power supply, empowering our submersible sewage pumps to handle large flow rates with ease and reliability.

The auto coupling set, synonymous with a guide rail set/system, revolutionizes maintenance by allowing pumps to be effortlessly lifted or lowered in a sump or chamber without disconnecting any fittings or pipes. This standard kit comprises a base (often referred to as a 'duckfoot' or 'pedestal'), a pump adaptor/guide hook, and an upper rail positioning bracket, complete with lifting chains and shackles. Depending on the model, the pump navigates one or two guiding rails (not included) for precise seating and easy removal.
The guide rail system includes the following essential attachments,
A sturdy fixing stand,
A secure locking arrangement,
A precisely crafted bend pipe.
