Rule Pumps 12 Volt DC non-automatic and automatic bilge pumps 360 GPH to 3800 GPH.
Rule’s non-automatic cartridge series bilge pumps offer traditional operation activated by a float or panel switch. Removal of the motor cartridge allows for easy cleaning of the strainer and impeller if clogged with debris. Rule Pumps 12 volt DC automatic computerized bilge pumps do not require float switches.
When water enters the bilge, and reaches a certain height (2-3/4 inches) a sensor turns the pump on. After the water is pumped out, another sensor shuts the pump off.
