Submersible Sewage Pump (WQ/QW Series) - Tengsheng Pump Manufacturing (Shanghai)

The submersible sewage pump (referred to as submersible waste pump, typical models: WQ/QW Series) manufactured by Shanghai Tengsheng is a core submersible device for non-clogging sewage lifting and discharge. Exclusively engineered for sewage and wastewater containing fibers and solid particles, it is adaptable to diverse scenarios including municipal engineering, industrial facilities and construction projects. It features core advantages such as no need for pump house construction, clog resistance, durability and flexible installation.

Product Description

Also known as submerged direct-coupled sewage lifting pump, our product integrates a hermetically sealed motor and pump body (IP68 rating). It operates fully submerged without requiring a dedicated pump house, and is capable of conveying sewage and wastewater containing fibers, sludge and solid particles (with diameter up to 50% of the pump's nominal bore). Designed for 380V AC three-phase power supply, it serves as an optimal alternative to conventional sewage pumps, effectively reducing both project investment and operation & maintenance costs.

Core Selling Points

Super strong anti blocking, continuous operation of large channel single/double blade impellers, capable of passing through 5 times the diameter of the pump with fibers and about 50% diameter solids; Partial tearing mechanism, crushing long fibers to reduce blockage and downtime, maintenance frequency reduced by 70%, suitable for high impurity working conditions
Safe sealing, ultra long lifespan dual channel series connected tungsten carbide mechanical seal+oil chamber isolation, oil-water probe warning; IP68 waterproof, H-class insulation, continuous operation for more than 8000 hours, no leakage underwater, motor life extended by 3 times
No need to build a pump room, cost reduction of 50%+integrated submersible design, no need for pump room civil engineering; Double rail automatic coupling installation saves infrastructure costs, shortens installation period, and eliminates the need for underground maintenance
Efficient and energy-saving, suitable for wide permanent magnet/high-efficiency asynchronous motors, CFD optimized hydraulic model, saving 15% -30% energy compared to traditional pumps without overloading the full head, suitable for flow rates of 10-400m ³/h and head conditions of 5-60m
Material selection, suitable for complex media such as cast iron/304 stainless steel overcurrent components, acid and alkali resistant, suitable for multiple media such as domestic sewage, industrial wastewater, and livestock wastewater
