The Rule 500GPH Standard Bilge Pump is built around a next-generation design that produces its rated flow at just 12V rather than the higher voltage older Rule pumps needed to hit the same numbers, a better match for typical on-board voltage.
A hidden air vent under each strainer tab releases air trapped in the pump housing to prevent airlocking, and true electromagnetic suppression (EMC) along with a built-in thermal cell protect the pump and the boat’s electrical system when things run hot.
It’s non-automatic, meant to pair with a panel switch or Rule float switch, and it’s submersible and ignition protected with a high-efficiency, low-amp motor, a stainless steel shaft, and a built-in backflow preventer. Browse more bilge pumps.
