RULE-MATE 500GPH AUTO BILGE PUMP RM500B

$99.99

This RULE-MATE 500GPH AUTO BILGE PUMP RM500B is a fully automated bilge pump using a solid state water reacting technology removing the need for a separate float switch. The sensor’s unique “field effect” technology is eco-friendly because straight motor oil in the bilge will not turn on the pump.

The new Rule-Mate bilge pumps operate using an internal level sensor. The RULE-MATE 500GPH AUTO BILGE PUMP RM500B switches on when the water level reaches 2″/5cm, and the pump will automatically activate, removing water from the bilge. When the water level reaches 3/8″/0.9cm the pump will turn off until the water level rises again.

Rule-Mate bilge pumps provide ultimate pumping performance, which helps keep your bilge clear of nuisance water, building on the genuine Rule design. 

Bilges are not always clean and free from debris. If the level sensor becomes fouled by debris or contaminated water, Rule-Mate’s unique back up feature will prevent the pump from entering a run-on condition, protecting the battery while maintaining automatic operation. So ,it has embedded programming that can sense when the pump is working but not pumping water to protect the pump, vessel, and the boat’s batteries.

Includes a straight 3/4″ hose fitting, a snap-on strainer for easy cleaning, and an anti-fouling impeller. Each pump has a 3-year limited warranty.

Features:

  • Higher flow — the 500GPH pump has an optimized impeller to provide up to 10% more flow at the same amperage
  • Auto sense intelligence — integral water level sensor controls the pump automatically
  • Back-up feature — prevents continuous running if sensor is fouled by debris, pump reverts to 2.5 minute cycle mode
  • Smaller footprint — the new Rule-Mate is 2/3 the size of older models
  • Built-in Thermal Cut-Off (TCO) — provides added protection for the pump and the boat
  • Back flow prevention — reduces the amount of water left over in the bilge, reducing odor and helping keep your bilge cleaner
  • Hidden air vents in the body — helps prevent air locking in challenging plumbing installations and helps with the check valve
  • Threaded discharge — easier installation, easier maintenance
