The Rule Mate RM1100B Automatic Bilge Pump is designed to deliver high-capacity performance in a compact footprint. Featuring integrated level sensing, this 12V submersible pump eliminates the need for a separate float switch—automatically activating at 2" (5cm) of water and shutting off at just 3/8" (0.9cm).

Ideal for medium to larger leisure vessels, the RM1100B offers powerful 1100GPH (4164 LPH) flow and is engineered for maximum reliability. Built-in thermal cut-off protection safeguards the motor and vessel during extended operation.

Its intelligent backup sensor system detects if oil or debris blocks the water sensor. When blocked, it reverts to a timed 2.5-minute cycle mode to maintain bilge dryness until the sensor clears and resumes normal operation.

Key Features:

  • 12V DC, 3.8A draw (7.5A fuse)

  • Flow rate: 1100GPH (800GPH @ 1m head, 500GPH @ 2m head)

  • ISO 8846 & ISO 8849 marine compliant (ignition & bilge standards)
