Rule-Mate 500 Bilge Pump 12V 500 GPH

The Rule-Mate 500 is a fully automated bilge pump designed for marine vessels requiring reliable water removal. It operates on a 12V electrical system and delivers a flow rate of 500 GPH or 1893 LPH. The unit uses state-of-the-art water sensing technology to activate automatically when water rises and shut off once the water is removed. No separate float switch is required for operation.

Practical limits of water-sensing automation

The pump relies on electronic water sensing rather than a mechanical float, so it activates based on water presence without moving switch parts that can jam. It includes a back flow preventer to stop water from re-entering the bilge after the pump shuts off. The anti-fouling impeller helps maintain performance in environments where debris or slime may be present. Ignition protection allows safer use in engine compartments where sparks are a concern.

Submersible 12V pump with 500 GPH capacity

This pump is built for submersible installation in bilge areas and requires a 12V power supply to run. Its 500 GPH rating defines the maximum volume it can move under open-flow conditions, making it suitable for small to medium-sized boats. Buyers needing higher flow rates for larger vessels or faster dewatering will need a pump with a greater GPH rating. The three-year warranty covers defects in materials and workmanship under normal use.

  • Fully automated operation without a float switch

Questions about this item

Which Rule Rule-Mate 500 version should I choose for my boat?

The Rule-Mate 500 is offered as a single 12V model rated at 500 GPH and 1893 LPH, so there are no alternative capacities or voltages to select from.

What does the 500 GPH rating mean when the pump is installed in the bilge?

The 500 GPH (1893 LPH) rating is the open-flow capacity; actual output will be lower once discharge hose, head height and any fittings are added to the system.

What power connection does the 12V pump use and what does it limit?

The pump connects to a 12V DC supply and its ignition-protected motor limits the risk of sparks in enclosed bilge areas.
