Automatic 500 GPH Bilge Pump - 12 Volt

Rule-Mate fully automatic submersible bilge pumps  with Rule's exclusive "Spongeability" feature. This new innovative design incorporates the bilge pump and water sensor in one single housing. The unique Rule "Spongeability" feature leaves the bilge the driest ever - when water in the bilge reaches a certain height, the sensor automatically activates and the pump runs until water is pumped out, reducing boat weight, saving fuel and minimising bilge odour. When the float switch drops and the pump senses no load against the impeller, the shut off phase begins. At that point the pump will run an additional 15 seconds allowing the pump to take the bilge water level down an additional 10mm. Heavy duty Rule motors, supplied with 16 gauge extra-long 120mm wiring.
