4kw 3hp 20m³/h 30m Explosion-Proof Submersible Sump Pumps submersible slurry pump Low Head High Discharge Pump For Sewage Water

The WQB20-30-4 is an efficient submersible pump designed to meet medium head requirements, suitable for a variety of applications such as wastewater treatment, industrial drainage, and water removal at construction sites. This pump offers a maximum flow rate of 20 cubic meters per hour (m³/h) with a head reaching up to 30 meters, powered by a robust 4 kW motor, ensuring stability and efficiency when handling complex fluids. The overcurrent components are made from high-quality materials like 304 or 316 stainless steel, providing excellent corrosion resistance, making it ideal for long-term reliable operation in harsh environments.

The WQB20-30-4 features innovative hydraulic design that effectively reduces the risk of clogging and enhances energy efficiency. It also comes equipped with high-performance sealing technology to ensure leak-free operation, thereby reducing maintenance frequency and extending the lifespan of the pump. To further enhance reliability, users can opt for an intelligent monitoring system that provides real-time data on critical parameters such as temperature, pressure, and vibration. This enables predictive maintenance, minimizing unexpected downtime. The compact design facilitates easy installation and maintenance, making it particularly suitable for use in space-constrained areas.
