LWN automatic submersible pump

Main Feature

The LWN submersible pump is internally equipped with a protection device. The motor is located at the upper part of the electric pump and is a single-phase or three-phase asynchronous motor. The pump is located at the lower part of the motor and is a centrifugal impeller and a volute structure. The dynamic seal between the pump and the motor is double. End mechanical seal. The static seal at each fixed stop is made of an oil-resistant rubber "O" ring seal. Due to its small size and light weight, this series of electric pumps are suitable for rural underground pumping, farmland irrigation, garden watering, and domestic water. It can also be used to eliminate industrial water, construction, water supply and drainage, and aquaculture.
