Core Positioning & Selling Points

Core DefinitionIt is a submerged direct-coupled sewage lifting pump with an integrated hermetically sealed motor and pump body (IP68 rating). Operating fully submerged without the need for a dedicated pump house, it can convey sewage and wastewater containing fibers, sludge and solid particles (with diameter up to approximately 50% of the pump's nominal bore). Designed for 380V AC three-phase power supply, it is an optimal alternative to conventional sewage pumps, effectively reducing project and operation & maintenance costs.

Non-clogging Sewage Pump 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
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
