QD Multi-stage Submersible Pump

The QD multi-stage submersible pump consists of a pump, a seal and a motor. Its impeller uses a radial vane structure. The double-end mechanical seal and the fixed-mouth seal are made of oil-resistant rubber seals for static sealing, which makes them have good sealing.

This series of QD multi-stage submersible pumps uses a multi-stage impeller structure. It has a high lift and wide application. It is an essential water supply and drainage tool for farmland irrigation and drainage, garden sprinkler irrigation, underground water pumping, water tower water supply, urban construction, and industrial and mining enterprises.
