The Davies Pumps Hydrogenie HG 2 auto pump controller is a simple and reliable device to control and protect a single phase pump up to 1.5Kw (8A). The controller has 1″ ports for simple installation in most pump systems. The HG2 controller will activate the pump when the system pressure drops below 1.5bar and turn the pump off when pressure is above minimum required and the flow has stopped.

It will protect the pump from damage in case of a run dry failure and will attempt periodically over 24 hours to auto restart or can be manually restarted with simple push button.

Optional gauge can be fitted to show pump performance and for simple trouble shooting of system.
