A device that protects the pump against damage caused by operation without water. The device will automatically stop the pump when the water pressure in the installation drops below the shutdown level - 0.7 bar. The device is equipped with a RESET button. The pump will be started for the first time after pressing the RESET button.
When the pressure in the installation exceeds 1.1 bar, the device will start operating maintenance-free. The device should operate in water networks equipped with a hydrophore tank. The device can be directly connected to pumps with single-phase motors.
For pumps with three-phase motors, the device can be connected via a contactor. The device is intended only for surface pumps. Attention! The HYDRO-BLOCK pressure controller does not replace a pressure switch
