The Rule 500GPH Electronic Sensing Bilge Pump - 12V, part number 25SA, is designed for marine applications requiring automated water removal and power conservation. This pump operates by sensing water presence through impeller resistance, activating for approximately one second every 2.5 minutes to check for water. If resistance indicates water, the pump runs continuously until the water level is between 1/8" and 3/8", then reverts to its sensing cycle. This mechanism eliminates the need for an external float switch, contributing to a more streamlined installation and reduced power consumption. Key features include a built-in thermal cell for overheat protection, electromagnetic suppression (EMC), and a backflow preventer with a hidden air vent to prevent airlocking. It is a submersible, ignition-protected unit with a high-efficiency, low-amp motor and a stainless-steel shaft, suitable for buyers seeking a compact, automatic bilge solution.
The pump turns on for approximately one second every 2.5 minutes to sense for water using impeller resistance. If water is detected, it runs until the water is removed, then resumes its sensing cycle.
The pump includes a check valve with a hidden air vent to prevent airlocking and a backflow preventer. It also features a built-in thermal cell and electromagnetic suppression (EMC).
This bilge pump is designed for 12V systems. It features a high efficiency, low amp motor for power conservation.
No, this pump is completely automatic with a manual override and does not require a separate float switch. Its electronic sensing mechanism handles water detection and pump activation.
