The Rule Mate RM800B Automatic Bilge Pump is a powerful and space-saving solution for keeping your bilge dry—without the need for a separate float switch. This compact 12V submersible bilge pump automatically activates when water reaches 2" (5cm) and shuts off at just 3/8" (0.9cm), ensuring quick, efficient water removal.
Smaller than previous models, the RM800B delivers high output in a reduced footprint and features a built-in thermal cut-off for added safety. With an output of 800 GPH (3028 LPH), it’s perfect for a range of leisure vessels, supporting heads up to 3 metres.
The built-in smart sensor checks for water resistance at the impeller. If the sensor is blocked by oil or debris, the pump switches to timed auto-cycle mode (every 2.5 minutes) until the issue clears—ensuring dependable performance even in demanding conditions.
