CONTROL ARRANGEMENT FOR WATER PUMP

摘要

A control arrangement for a pump comprises a dual switch control of a pressure switch (10) provided inside a pump head together with a high current sense (12). The pressure switch (10) is adapted to turn the pump (14) on when an outlet is opened with consequential pressure drop causing that state to be latched enabling the back pressure to rise to any level and the pump (14) to turn off when the outlet is closed and the current sense (12) activates.
