4INCH QGD series stainless steel submersible screw water pump

Installation and Application
The QGD/QG type submersible screw pump is composed of three main parts: the pump body, mechanical seal, and motor. The mechanical seal is located between the pump and motor, ensuring a secure connection. An internal protector helps prevent damage caused by power fluctuations, clogging, or overload. This pump is ideal for pumping clean water without abrasive particles and liquids that are chemically non-aggressive to the pump’s materials. It is widely used in well pumping, river pumping, farm irrigation, water supply, mining, and industrial drainage.
