Submersible electric motors DAP-6-3, PADV-8-17, etc.

Hermetic asynchronous submersible DAP electric motors are designed for use as part of electric centrifugal borehole units of type 2ECV.

Advantages of DAP series electric motors:

• the life of the electric motor before major repairs is 25,000 hours;
• the internal cavity of the electric motor is isolated from the pumped water, thereby eliminating the possibility of sand getting into the bearings and corrosion of electrical iron, which significantly increases the service life of the electric motor;
• high efficiency during the entire service life.

characteristics of the engine by the diameter of the well, reduced by 25 times and rounded:
6 – for a well with an inner diameter of 150 mm casing pipe
8 – for a well with an inner diameter of 200 mm casing pipe
10 – for a well with an inner diameter of 250 mm casing pipe
12 – for a well with an inner diameter of 300 mm casing pipe
130 - rated power, kW

• DAP electric motors. Technical specifications

The submersible asynchronous electric motor PADV is designed to complete pumping units of the ECV type. Technical specifications are specified at a rated voltage of ~ 3 x 380V, 50 Hz. To connect to the power grid, the electric motor is equipped with three round-section wires. The method of connecting the windings is "star". The starting method is direct.
