The Rule 800GPH Electronic Sensing Bilge Pump (part number 20SA) is a 12V submersible pump designed for automatic water removal in marine applications. This unit operates by sensing water presence through impeller resistance, activating for approximately one second every 2.5 minutes to detect water. If resistance is detected, the pump runs continuously until the water level is between 1/8" and 3/8", then returns to its sensing cycle. This design eliminates the need for a separate float switch, contributing to power conservation. Key features include electromagnetic suppression (EMC), a built-in thermal cell for overheat protection, and a stainless-steel shaft. A check valve with a hidden air vent is included to prevent airlocking. This pump is suitable for IT buyers managing marine equipment where reliable, automatic bilge water management and power efficiency are priorities.
