Rule-Mate Automatic Bilge Pump 1100 GPH – 12 volt – New Design

All NEW versions of the Rule-Mate fully automatic submersible bilge pumps offering more compact size with high performance & reliability.
The RULE brand builds on more than 50 years of operational experience, innovation, design excellence & application expertise to offer modern solutions to today’s boat owners and boat builders.
NEW Rule-Mate Automatic bilge pumps are packed with many improved and additional features that are not available in other brands of bilge pumps.

  • More compact size – only 2/3 the size of the previous versions
  • Auto-sense intelligence fully automatic water level sensing
  • Fully automatic pump in 1 common compact housing
  • Pump and sensor are internally common wired for easy installation
  • No battery drain other than when the pump is in use
  • 1100 GPH models in both 12v & 24v versions
  • Optimised impeller design gives up to 10% higher flow than previous versions – at the same amperage
  • Built-in thermal cut-out (TCO) to protect the pump & the vessel
  • Supplied with back flow prevention – check valve in outlet port
  • Anti-Airlock design has hidden air vents in the pump body
  • Safety back-up operating mode prevents continuous running if the sensor or impeller is fouled by debris
  • Pump check feature – touch and hold for 5 seconds on the “touch here” button on the pump casing – to instantly check the operation of the pump

The NEW Rule-Mate bilge pumps operate using an internal water level sensor. When the bilge water level reaches 62mm height the pump will automatically activate, removing water from the bilge.
When the water level goes down to 16mm height the pump will automatically shut off until the water level rises again. Hidden air vents in the body of the pump helps prevent air locking in challenging plumbing installations. A check valve is included in the discharge nozzle to prevent water running back into the bilge.

  • The smaller footprint of the NEW Rule-Mate pumps (only 2/3 the size of the previous versions) allows mounting in tighter spaces.
  • Threaded discharge nozzle for easier installation and maintenance
  • Removable strainer to access impeller area to clear any debris
  • 3rd wire allows for manual over-ride using a Rule switch panel (see below – RWB23 or 107 12 volt, RWB24 or 5188 24 volt)
  • 3 year limited warranty

    RuleMate Intelligence - RuleMate bilge pumps have built-in programming that can sense when the pump is running but not pumping water to protect the pump, vessel, and the vessel’s batteries. If debris fouls the sensor or the pump becomes air-bound, the pump will stop running and begin to “check” for water every 2-1/2 minutes. Once the debris is removed, the pump will revert to its normal operation, turning on when the water reaches approximately 2-1/2" and shutting off at 5/8". Our RuleMate bilge pumps contain a fail-safe back-up program that measures the amount of work the motor is performing and the length of time the motor is running. If debris, such as a wet paper towel or leaves, became lodged against the pump, it could “trick” the pump into thinking water remained in the bilge which could deplete the vessel’s battery. If the circuit board senses the motor is running but doing little work (not pumping water) for longer than fifteen seconds, the pump will enter into a cycling mode in the same fashion as the computerized pumps. The pump will sense water every 2-1/2 minutes and if it senses water, it will continue to run until the water has been removed from the bilge. After the debris is removed, the pump will automatically revert to the level sensing mode.
