The WQP stainless steel sewage pump is a type of pump equipment that integrates a submersible motor with an efficient non-clogging pump body in a coaxial manner, and is fully sealed before being directly submerged in liquid for operation. It is specifically designed for the transportation of sewage and wastewater containing solid particles, fibers, impurities, feces, and various suspended substances.

Product details
Pure Copper Winding Motor
Built with Grade 180 high-temperature copper wire from the Jintian brand, delivering superior electrical conductivity and extended operational lifespan.
High-Precision Stainless Steel Rotor
Manufactured from stainless steel with a protective coating that resists rust and moisture, ensuring stable and smooth rotation over time.
Premium NSK Bearings
Incorporates high-grade imported bearing steel, offering tighter tolerances, reduced rotational drag, and noticeably better mechanical efficiency.
Wide-Channel Clog-Resistant Impeller
Features a generously sized, obstruction-free flow path that effectively blocks debris buildup. Delivers strong, reliable discharge performance while maintaining excellent durability against abrasive wear.
Product advantages
Clog-Free Hydraulic Design
The pump incorporates single/dual-channel or vortex-type impellers with generously sized, smoothly contoured flow paths. Solids and long-fiber impurities up to 30–60% of the discharge diameter can pass through effortlessly, eliminating the need for add-on cutters. This design intrinsically prevents blockages and sustains trouble-free, continuous operation.
Fully Submersible Build for Simple Service Access
The motor and pump are enclosed in a single hermetically sealed assembly that operates directly inside the wet well or sump, removing the requirement for an above-ground pump house and reducing civil works expense. When paired with an auto-coupling system, the unit can be lifted along guide rails to ground level for inspection or repair-no confined-space entry is needed, improving both safety and maintenance speed.
Multi-Stage Seal System for Dependable Watertightness
Two independent, high-durability mechanical seals (e.g., silicon carbide or tungsten carbide faces) are installed in series, with an intermediate oil chamber that provides lubrication and dampens hydraulic shocks. An optional leakage detection probe can be added for early warning. This configuration reliably prevents sewage migration into the motor cavity during prolonged submersion and frequent start-stop cycles, ensuring consistent electrical safety.
Application fields
Urban Wastewater Transport & Boosting
Serves as intermediate lift stations within sewer networks, factory-assembled pump stations, and intake chambers at treatment facilities.
Residential & Commercial Dewatering
Handles drainage from basements, underground garages, bomb shelters, and elevator shafts; also lifts septic tank effluent from apartment complexes and housing estates.
Industrial Effluent Handling
Transfers process wastewater generated by light manufacturing, textiles, pulp and paper, and food processing sectors (material specification depends on the chemical aggressiveness of the fluid).
Healthcare & Hospitality Waste Streams
Manages sanitary waste, laundry discharge, and greasy kitchen effluent from hospitals, hotels, and similar institutional facilities.
