Rule-Mate 1100 Automatic Bilge Pump

Brand:

Rule

Part no:

RM1100B

Rule's automatic 1100 GPH bilge pump (RM1100B), which senses water with an internal level sensor, so no float switch is needed; if debris fouls the sensor, it falls back to checking for water every 2.5 minutes. Rule's Rule-Mate manual (950-0535 Rev E) gives 1,128 GPH at zero head but 792 GPH at 3.3 ft and 456 GPH at 6.7 ft, without stating a test voltage. It draws 3.8 A at 12 V on a 7.5 A fuse, and Rule says it is for normal bilge water, not damage control.
