7.5kw 5.5hp 25m³/h 50m Explosion-Proof Submersible Sump Pumps submersible slurry pump Low Head High Discharge Pump For Sewage Water

The WQB25-50-7.5 is a high-efficiency submersible pump designed for reliable performance in challenging environments such as industrial drainage and wastewater management. With a flow rate of 25 cubic meters per hour (m³/h) and a maximum head of 50 meters, this pump excels in applications requiring significant lift capacity. Powered by a 7.5 kW motor, it ensures robust operation while maintaining energy efficiency. Constructed from corrosion-resistant materials like 304 or 316 stainless steel, the WQB25-50-7.5 resists wear and tear, even when handling aggressive fluids. Its innovative hydraulic design minimizes clogging risks and enhances performance, supported by superior sealing technology that guarantees leak-free operation. An optional smart monitoring system provides real-time data on essential metrics, facilitating predictive maintenance and reducing unexpected downtime. Compact and easy to install, the WQB25-50-7.5 offers dependable and long-lasting fluid transfer solutions.
