Product Introduction
Applicatioms

This heavy-duty submersible sewage pump features a robust, all-cast-iron construction with a coaxial design that integrates the motor and pump body into a single, durable unit. Located beneath the pump body, the impeller—available in large-aperture vortex or single/double-channel configurations (as shown in the image, the bottom impeller features a wide design with a distinct red inner lining to enhance wear resistance and flow capacity)—delivers exceptional non-clogging and anti-winding performance, effectively allowing for the passage of large solid particles and long fibrous debris.

Key Features:

High-flow design: The bottom impeller features a wide opening, providing strong solids-handling capability (capable of passing solid particles up to approximately 50% of the pump's discharge diameter, and fibrous materials up to 5 times the diameter).

Fully submersible structure: The motor incorporates multiple built-in protection mechanisms (against water ingress, overheating, etc.), ensuring stable and reliable long-term operation within sewage environments.

Corrosion- and wear-resistant cast iron material: Ideal for use in harsh sewage environments.

Compact structure: Offers flexible installation options (suitable for both portable and automatic coupling guide-rail installations).

Integrated support base: Features a bottom support stand for smoother and more stable operation.

This pump represents a typical WQ/QW-series non-clogging submersible sewage pump, making it particularly well-suited for handling sewage, wastewater, and rainwater containing solid particles, fibers, and sediment.

1. Product Applications

Sewage Lifting and Discharge: Automatically lifts sewage from collection pits and holding tanks to municipal sewer networks or sewage treatment systems.

Rainwater/Floodwater Drainage: Emergency drainage for basements, parking lots, tunnels, and low-lying areas.

Industrial Wastewater Treatment: Discharge of factory production effluent and process wastewater containing particles or fibers.

Municipal Engineering: Sewage pumping stations, urban drainage systems, and influent lifting for sewage treatment plants.

Building Drainage: Discharge of domestic sewage from hospitals, hotels, shopping malls, and residential complexes.

Other Applications: Mine dewatering, wastewater treatment for livestock farms, emergency flood drainage, etc.

Working Principle: The motor drives the impeller to rotate at high speed, generating centrifugal force that draws sewage in from the bottom and discharges it through a wide flow channel. Thanks to the vortex or large-channel impeller design, solid debris passes naturally along with the fluid flow, minimizing the risk of entanglement or clogging within the pump body.

2. Applicable Locations

Municipal sewage pumping stations and sewage treatment plants

Building basements, underground parking garages, and equipment floors

Wastewater treatment workshops in industrial parks, chemical plants, food processing facilities, paper mills, etc.

Domestic sewage collection pits in hospitals, hotels, and shopping malls

Drainage projects for mines, tunnels, and dams

Rural livestock farms, biogas digesters, and rainwater collection wells

Any low-lying area prone to water accumulation that requires the handling of sewage containing solid impurities
