Dry Run Protector for Borehole Pumps

Dry Run Protector for Borehole Pumps

What is the Pump Protector – DRP?

The Pump Protector - DRP is an innovative electronic device that guarantees optimal protection of the submerged pump from dry running. Additionally, it also protects the motor from burning out in case of repeated starts and stops.
Where is the DRP installed and how does it work?

The DRP is ready for use, integrated into the connection cable and needs no further installation. In case of water shortage, the DRP stops the pump immediately, the water drops below the DRP and restarts the pump automatically a short time after the water rises above the DRP. In contrast to traditional solutions, no additional cables, sensors and control boxes are needed.

In case of repeated starting and stopping of the pump, such as when the air in a pressure tank is low or the membrane is damaged, the DRP registers the frequent starts and stops and will automatically stop the motor from burning out. The DRP may be reset simply by disconnecting the power supply.
