-up to 3/4HP with 110V -up to 1.5HP with 220V This electronic unit controls start and stop of the pump when any tap or valve of the system is opened or closed. When the pump is started, it remains running as long as there is demand by the user thus supplying the water main at constant flow rate and pressure rate. It is provided with a special check valve (to protect against risk of water hammer).
