Shakti Submersible Well Pump Motors General Information

High Motor Efficiency
- High efficiency electrical design for low operation cost.
- Elevated starting Torque, Mechanical Compactness, Reliability, Superior Performance.
- Water lubricated thrust and radial bearing enable a maintenance free operation.
- Special Cooling fluid for a better lubricant effect to increase life of moving parts. The liquid with its high thermal capacity gives the motor superior overload capabilities.
- The motors are ready to operate, providing frost protection down to -15~C.
- Sand slinger and shaft seal/Mechanical seal for high performance in Sand.
- A preloaded special diaphragm ensures pressure compensation inside the motor.
- Standard motor with taping winding Insulation for motor ambient of 30~C with a Min.
- NEMA Standard coupling dimensions.

Shaft Seal / Mechanical Seal - The choice of material is SiC/ SiC provides optimum wear resistance and long life. The spring loaded shaft seal is designed with larger surface area and sand shield. The result is a minimum exchange of pumped motor liquids and no penetration of particles and Sand.

Protection Against Up Thrust - In Case of a very small counter pressure in connection with start-up there is a risk that the entire pump body may raise. This is called up thrust. Up thrust may damage both pump and motor. Therefore both Shakti pumps and motors are protected against as standard, preventing up thrust from occurring in the critical startup phase. The protection consists of either a built-in stop ring.

Built In Cooling Chambers - In all submersible motors an efficient cooling chambers at the top and at the bottom of the motors, and by an internal circulation of motor liquid. As long as the required flow velocity cooling of the motor will be efficient.

Over Temperature Protection - For Shakti Submersible motors accessories design for retrofitable PT 100 Senor for protection against over temperature is available. When the temperature becomes too high, the protection device will cut-out and damage to the pumps and motor be avoided.
