RULE RM1500 AUTOMATIC BILGE PUMP

RM1500 AUTOMATIC BILGE PUMP.  Rule Automatic bilge pumps eliminate the need for a separate float switch to activate the pump. Once power is supplied, starting and stopping is completely automatic. The pump checks for water every 2 ½ minutes by turning on for a second and measuring load against the impeller. If water is present, the pump remains on until the water is removed. Thereafter the pump resumes its 2 ½ minute check cycle. The automatic pumps feature two positive leads: an automatic (brown) and a manual override (brown with a white stripe).
