Rule-Mate Automated Bilge Pumps
Rule LoPro Bilge Pumps
When water enters the bilge and reaches 2-3/4" (7cm), a sensor turns on the
pump. After the water is pumped out, another sensor shuts off the pump. The
Rule-Mate II series is available in 500, 750, 1100, 1500 and 2000 GPH models.
These pumps feature an all-in-one pump and switch, which means no float
switch is required. They also include a snap-off strainer for easy cleaning,
anti-fouling impeller, and limited three-year warranty. Rule-Mate pumps have
been chosen by many of the world’s leading boat builders as a compact and
reliable bilge system.
Our latest automatic pump design, the LoPro allows for pumping out of tight
spaces and shallower bilges. The LP900S model uses a unique double system
for sensing water, to ensure that the pump only ever operates when water is
present, and switches off efficiently when it’s not. If water is sensed, the pump
will spin the impeller as a double check. If water is confirmed, the pump will run
to empty the bilges. A second sensing mode is also available, which sets the
pump to run at either 1.3" (3.25cm) or 2" (5cm). The pump body rotates to allow
discharge in any direction. A selection of straight and 90 degree ports, and a
non-return valve for use with straight ports, are supplied. The LP900D model
has no sensors and can be operated via a manual switch or a float switch.
