Product Description: Rule Mate Automated Bilge Pump Model RM500 (42237084774)

The Rule Mate Automated Bilge Pump RM500 is an essential piece of equipment for any boat owner, designed to keep your vessel dry and safe by automatically removing excess water from the bilge. This high-performance pump is manufactured by Rule, a leading name in marine bilge pumps, known for their durability and reliability.

The RM500 pump features a powerful 12-volt DC motor that can discharge up to 4,000 GPH (Gallons Per Hour) at 0.5 head, ensuring rapid water removal. This pump is designed for boats with bilge capacities of up to 1,500 gallons. It comes with a heavy-duty, thermoplastic impeller that is self-priming and capable of handling both freshwater and saltwater.

One of the key advantages of this Rule bilge pump is its automated operation. It is equipped with a float switch, which activates the pump when the water level in the bilge reaches a predetermined point. Once the water level recedes, the switch turns off the pump, conserving energy and prolonging the life of the motor.

The Rule Mate RM500 is designed with a corrosion-resistant, powder-coated housing that provides excellent protection against the harsh marine environment. The pump is also easy to install, with a quick-connect, 3/4" NPT discharge outlet and a 1 1/2" NPT suction inlet.

This Rule bilge pump is ideal for use on small to medium-sized boats, including sailboats, powerboats, and inflatables. It offers peace of mind, knowing that your boat's bilge is being continuously monitored and any excess water is being automatically removed, preventing potential damage from flooding.

In summary, the Rule Mate Automated Bilge Pump RM500 (42237084774) is a high-performance, reliable, and easy-to-install solution for keeping your boat's bilge dry and safe. Its powerful motor, self-priming impeller, and automated operation make it an essential addition to any boat.
