Thank you both for responding. The pumps I am dealing in are 500 gpm 7 bar with 4 inch suction side. they are supposed to run on auto but the foot valve develops leakage and pump runs dry. I need a cheaper solution (no sensors and alarms please)
I want to attach a priming tank to an existing set of pumps. the pumps take suction from an underground tank with suction lines having foot valve, thus normally pumps remain primed. I understand that generally a tank having 3 times the volume of suction line is used. But once I start the pump it...
