High accuracy in overload and dry run current



This model automatically switches ON and OFF the Motor.

When the water level of the overhead tank becomes low means water gets down from the middle sensor and if water is present in the underground tank or sump, the motor gets started automatically. The tank starts filling up. when the water level reaches to the higher level, the motor automatically gets switched off.


This model has dry run protection, so it only starts the motor if water is present in the underground tank or sump.

It has current based dry running. If the motor runs without water, then it takes lower ampere (current) then actual current. so when the motor current gets down from actual current, it stops the motor and protects the motor from dry running. 

Sensing element: S.S sensor, it is free from oxidation, long life. Any conducting wire can be used for sensor.

All signals pass in sensors through the AC filter circuit that improves the life of sensor,

Isolated supply provided

Sensor fault detection provided, if sensor got failed LED start blinking

Auto and Manual mode switch available. In auto mode the motor starts and stops automatically. In manual mode the user can start and stop the motor by pressing the start and stop button of the controller. No additional wiring is required to operate the motor manually. 

High quality ABS. enclosure provided.

Fully automatic, controls from underground tank to overhead tank so no manpower required. Long service Life.
