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
All pumps are the same physical size – 73mm depth x 112mm Height. The length is 129mm to the end of the threaded discharge nozzle and totals 165mm including the screw-on hose port.
