Product Details

The Xylem Rule-Mate RM1100B is a fully automated submersible bilge pump designed to keep your boat dry without the need for a separate float switch. This 12-volt pump delivers 1100 gallons per hour (4164 LPH) of pumping capacity, making it ideal for powerboats, sailboats, and other marine vessels that require reliable automatic bilge water removal.

Intelligent Water Sensing Technology:

The RM1100B features state-of-the-art solid-state water sensing technology with an internal level sensor that automatically activates when water reaches 2 inches (5 cm) and shuts off when water levels drop to 3/8 inch (0.9 cm). The eco-friendly sensor design prevents accidental activation from straight motor oil, protecting waterways from contamination.

Key Features:

  • 1100 GPH maximum flow rate at 12V DC
  • No float switch required - integral water level sensor
  • Back-up feature prevents continuous running if sensor becomes fouled
  • Built-in back flow prevention check valve reduces residual water in bilge
  • Anti-fouling impeller design for reliable long-term operation
  • Hidden air vents prevent air locks in challenging installations
  • Quick-release inlet strainer for easy cleaning
  • Ignition protected for safe marine use
  • Low 3.8 amp draw conserves battery power
  • Compact footprint: 3.4"L x 2.9"W x 4.4"H
  • Threaded discharge accepts 1" or 1-1/8" hose barbs (both included)

Specifications:

  • Voltage: 12V DC
  • Amp Draw: 3.8A at maximum flow
  • Recommended Fuse: 7.5A
  • Maximum Head: 10 feet
  • Flow at 3.3 ft head: 792 GPH
  • Flow at 6.7 ft head: 456 GPH
  • Hose diameter: 1" or 1-1/8"
  • Overall length (including port): 6.4"
  • Weight: 1.1 lbs

The Rule-Mate RM1100B is submersible and built to withstand harsh marine environments. Backed by a 3-year limited warranty, this pump provides reliable protection against nuisance water accumulation in your bilge. Installation requires flexible hose (rigid piping not recommended) and mounting with marine-grade sealant at all mounting holes.

Best prices that I could find. Quick shipping

aaa

The complete set of online pictures helped ensure I was ordering the correct part. The only other thing that could have helped would be if the length of the cable was posted, or if there was a picture of it laid out next to a yardstick, so I knew the length of the total cable, and the sleeve.

easy to use

AMAZING!!!!!!!!!!!!!!!!!!!!

Processed and shipped out very quickly. I love when a website delivers! It was the best deal on the internet AND they gave free shipping! I will definitely do future business with Autoplicity. Thanks!
