Turn any pump (submersible or jet) into an automatic pump with this innovative Pump Controller. Simply wire directly to the pump motor, and the Controller will automatically sense a demand for water and turn the pump on accordingly. Replaces need for pressure tank and pressure switch, though we recommend this only for applications where space is limited for pump controls as pressure tanks still offer the most efficient pumping solution. Works on 115V and 230V motors, up to 1.5HP 230V pumps.
