4kw 3hp 75m³/h 8m Explosion-Proof Submersible Sump Pumps submersible slurry pump Low Head High Discharge Pump For Sewage Water

The WQB75-8-4 is a highly efficient and reliable submersible pump designed to meet the demands of various fluid handling tasks. With a flow rate of 75 cubic meters per hour (m³/h) and a maximum head of 8 meters, this pump is well-suited for applications such as wastewater treatment, light industrial drainage, and water supply systems. Powered by a robust 4 kW motor, it ensures consistent performance while maintaining energy efficiency, making it an economical choice for continuous operation.

The WQB75-8-4 can be made of durable materials such as 304 or 316 stainless steel, which has excellent corrosion and wear resistance, ensuring service life even in harsh environments. Advanced hydraulic design minimizes the risk of clogging and improves operating efficiency, making it particularly effective in handling fluids containing solids. Reliable sealing technology prevents leakage, reduces maintenance needs and extends the service life of the pump.
