Clear Water Deep Well Submersible Borehole Turbine Industrial Centrifugal Pumps

Submersible Borehole Industrial Centrifugal Pump Introduction
QLJ series submersible deep well pumps consist of motor and pump assembly, the struture is reasonable, easy to install and maintain, and with advanced hydraulic model, they adopting the core prodcued with the resin sand and the vane runners adopting the core technique that topcoated with epoxy, high efficiency which is 2-5% higher than that of QJ type submersibie turbine pump as well. They are modern machine for lifting water.
