The QSB type submersible electric pump belongs to the wet type upper pump small submersible electric pump, and the integrated machine pump works underwater, making it an ideal tool for extracting groundwater. This pump has the characteristics of simple structure, small volume, light weight, high efficiency and energy saving, and easy installation and maintenance. Widely used for irrigation of farmland, water supply and drainage of industrial and mining enterprises, and domestic water supply for urban residents.

Structural features:

The QSB submersible electric pump consists of two parts: the motor and the water pump. The water pump is centrifugal, using water lubricated bearings, and rigidly connected to the motor through a coupling. The motor is a closed water filled three-phase asynchronous motor. The winding adopts a water-resistant insulation structure, and both the guide bearing and thrust bearing are water lubricated bearings. A sand prevention mechanism is installed on the upper part of the motor to prevent sediment from entering the motor cavity.

Usage conditions:

1. The water temperature shall not exceed 40 ℃

2. The power supply is 50HZ, 380V

3. Electric pumps should be used within the range of rated flow to 1.2 times the rated flow.
