First, product overview

The submersible electric pump is a well pump, which is composed of a YQS type submersible motor and a QJ type submersible pump. Its main feature is the motor and pump together into the water to work without pumping station building, which has the advantages of simple structure, convenient operation and maintenance, high efficiency, safe and reliable operation.

Two, product uses

It is suitable for the extraction of ground water from deep wells, it is widely used in urban, industrial and mining enterprises, cooling systems, water supply and drainage and agricultural irrigation.

Three, the use of conditions

1, power supply: three-phase alternating current 380V (tolerance) 50), 5% Hz (tolerance) 1%).
