WQ Big Submersible Sewage Pump

Product Features

Our innovative overload-free hydraulic design allows for a wide operating range, high efficiency, minimal vibration, and smooth operation. It also ensures the passage of solid materials and resistance to fiber entanglement. The excellent dual end-face in-line installed mechanical seals and self-cleaning lower water seal function on the pump cover guarantee a lifespan of both seals exceeding 15,000 hours. The high reliability submersible motor is rated at H-class insulation, with a maximum operating temperature of 180°C. Pump body, pump cover, and oil chamber castings undergo electrophoretic treatment or paint coating to enhance corrosion resistance. The overall structure ofct the impeller mounting shaft, ensures reliable operation with the pump center positioned low.

Applications

1. Municipal Engineering & Water Utilities

•  Sewage Treatment & Pipe Network Transportation: Used in urban sewage treatment plants, municipal pipe network boosting pump stations, and rain-sewage confluence pumping stations; handles domestic sewage, mixed rainwater and sewage containing domestic debris, sediment, and suspended solids; requires 24-hour continuous operation, large flow, and medium-low head working conditions.

• Urban Flood Control & Drainage: Applied to urban road ponding drainage, underpass tunnels, underground pipe galleries and urban waterlogging emergency drainage; transports floodwater mixed with sediment, branches, domestic garbage, stones and other impurities; adapts to instantaneous large flow, emergency heavy-duty drainage and short-term high-load operation.

• River & Lake Bottom Sewage Discharge: Used for river channel dredging, lake bottom sewage and silt drainage; conveys high-concentration silt, sediment, water grass and floating garbage; suitable for deep water level, high sediment content and large flow drainage conditions.

  
  

2. Industrial Manufacturing

• Paper Making & Pulp Industry: Applied to papermaking wastewater, pulp residue mixed liquid delivery in paper mills; transports sewage containing a large number of paper fibers, wood chips and suspended impurities; adapts to fiber-prone winding and high viscosity working conditions.

• Food & Breeding Processing Industry: Applied to food processing wastewater, slaughterhouse sewage, breeding wastewater discharge; transports oily sewage, food residues, animal manure and organic suspended solids; adapts to easy-blocking and high organic matter content working conditions.

3. Water Conservancy and Agricultural Engineering

• Large-scale Agricultural Irrigation & Drainage: Applied to farmland flood control and drainage, agricultural breeding park sewage discharge, and irrigation water source boosting; transports agricultural sewage containing sediment, crop straws, weeds and pesticide residues; adapts to open-air, large flow and long-term operation conditions.

• Water Conservancy Project Construction: Used for foundation pit drainage, reservoir bottom sewage discharge, and dam construction wastewater delivery in water conservancy dams; conveys sediment, gravel and construction sewage; adapts to high head, deep water level and heavy-duty construction drainage.

4. Construction and Municipal Construction

• Underground Construction Drainage: Applied to subway foundation pits, high-rise building underground basements, tunnel construction sewage and mud drainage; transports construction mud, sand, concrete residues and groundwater; adapts to deep foundation pit, temporary large flow and harsh construction environment.

• Large-scale Commercial & Residential Sewage: Used in centralized sewage discharge pump stations of large commercial complexes, high-end residential quarters and industrial parks; transports domestic mixed sewage and construction waste water; adapts to centralized boosting, large flow and stable operation conditions.
