WQ Type Electric Sewage Pump

The WQ type submersible sewage pump is currently the most widely used and has the largest quantity of submersible non-blocking sewage pumps. It directly connects the submersible motor with the efficient sewage pump body coaxially and achieves overall sealing. After that, it can be directly submerged in sump tanks, sewage pits or septic tanks for operation. The impeller of the pump adopts a large channel, anti-tangling and non-blocking design, which can ensure smooth passage of sewage containing fibers, paper debris, feces and solid impurities during transportation, avoiding frequent blockages and shutdowns. This pump type is the main equipment for achieving sewage lifting and discharge in scenarios such as urban sewage pipelines, building basement drainage, municipal pump stations, industrial wastewater treatment and rural sewage management.

Core Power All-Copper Motor
High-quality copper wire with high rotational speed and strong suction, resulting in better efficiency
304 stainless steel rotor shaft
Made of SUS304 stainless steel material, environmentally friendly, durable and long-lasting
High-precision bearings operate smoothly, are wear-resistant and have a long lifespan
Precision oil seals are wear-resistant, anti-aging and prevent leakage
National standard motor with high cost-effectiveness
Stainless steel open impeller
High-quality impeller, prevents jamming, does not rust, and particles and impurities pass through without obstruction

True unobstructed flow capacity: With single/double flow channel impellers, vortex impellers or swirl impellers, the flow channels are wide and smooth, allowing solid particles with diameters up to 30% to 60% of the pump outlet diameter, as well as longer fibers and impurities. Without the need for additional cutting devices, it can effectively prevent blockages and ensure continuous operation.
Full submersible structure, easy installation: The pump and motor are integrated with an airtight seal, directly submerged in the sump for operation, without the need to build a ground pump house, saving construction costs. Combined with an automatic coupling device, it can be automatically lifted to the ground for maintenance along the guide rail without personnel going down the well, ensuring safety and efficiency.
Dual/multiple mechanical seals, reliable waterproofing: Two independent high-quality mechanical seals (such as silicon carbide/tungsten carbide) are used, with an oil chamber in the middle as a buffer and lubrication, and a leak sensor can be optionally selected. Under long-term submersible and frequent start-stop conditions, it effectively prevents sewage from entering the motor chamber, ensuring electrical safety.
Complete motor protection, suitable for harsh environments: Submersible motors usually adopt F-class or H-class insulation, equipped with sensors such as overheating protection, water leakage detection, and bearing temperature rise monitoring, which can work stably under partial submersion or frequent start-up conditions, extending the overall machine lifespan.
High efficiency and energy saving, low operating costs: The impeller and volute are optimized by water flow, maintaining high efficiency within a wide flow range, reducing energy consumption per ton of water conveyed. The motor efficiency complies with IE2/IE3 standards, and the economic performance is significant over the long term.

Municipal sewage collection and lifting: Midway pumping stations for sewage pipelines, integrated prefabricated pumping stations, and inlet pump rooms of sewage treatment plants
Building and community drainage: Water drainage from basements, underground garages, civil defense projects, and elevator pits; sewage lifting and discharge from septic tanks in residential buildings
Industrial wastewater treatment: Process wastewater discharge from industries such as light industry, textiles, papermaking, and food processing (materials selection needs to be based on corrosivity)
Hospital and hotel support: Upgrading and discharging of sanitary wastewater, laundry wastewater, and oily wastewater from kitchens
Rural sewage treatment: Village sewage collection stations, water lift for household septic tanks, and supporting small-scale integrated treatment facilities
Municipal flood prevention and emergency drainage: Rapid drainage of road water accumulation, drainage of culverts, and rapid deployment of temporary pumping stations
