Automatic working pressure systems build up with centrifugal self-priming pumps. Each set is ready for installation is made by a pump and a Hidromatic H1 pump controller which is a complete replacement of the traditional water system set consisting of a pressure switch and tank. The control of the pump is started after a pressure decrease (taps opening) and stopping when the water flow is interrupted at the maximum pressure level of the pump (taps closing). Protection against dry running.
