QJ Deep Well Submersible Pump
QJ Deep Well Submersible Pump
The QJ Deep Well Submersible Pump is a multi-stage vertical submersible pump designed for installation in boreholes and water wells for deep groundwater extraction, water supply systems, irrigation, and mine dewatering. The slim-line design is engineered for standard borehole diameters from 100 mm (4") to 400 mm (16").
Each pump stage adds head to the water, allowing total dynamic heads up to 600 m. The stainless steel bowl assembly and impellers provide corrosion resistance for groundwater containing dissolved minerals. The hermetically sealed submersible motor operates at depths up to 400 m.
Available in a wide power range (0.37 kW to 200 kW) with matching submersible motors. Variable frequency drive (VFD) compatibility enables energy-efficient flow control for fluctuating demand applications.
