Rule Mate Automatic Bilge Pump

Rule has been building bilge pumps for over 30 years. These pumps are preferred by recreational boaters, yachtsmen, and by commercial fishermen everywhere. An all-in-one pump and switch, Rule Mate automatic bilge pumps are eco-friendly and feature a solid state water-sensing technology eliminating the need for a separate float switch. Instead, when the water level rises, the pump turns on. When all water is removed, the pump will shut itself off. In addition, Rule Mate's sensor has unique "field effect" technology that only recognizes water. This means that if it detects a 100% concentration of oil, the pump will not activate. As such, Rule Mates are considered to be the most technically-advanced bilge pumps available on the market.

The Rule Mate Series is available in 500, 750, 1100, 1500, and 2000 GPH and is about 2/3 of previous models (500-1100 GPH models only). Hidden air vents within the body help prevent air locking in challenging plumbing situations and helps with the check valve. This pump features back flow prevention to reduce the amount of water left over in the bilge. This reduces odor and helps keep the bilge cleaner. It also features a snap-lock strainer base which makes it easier to clean and a thermal cut-off for added protection. The threaded discharge provides easier installation and easier maintenance.

  • No float switch needed
