Rule Non-Automatic Bilge Pump 500 GPH (1893 LPH) 12V

Description

The Rule 25DA is a 12V non-automatic bilge pump rated at 500 GPH (1893 LPH), designed for efficient removal of nuisance water from marine bilge compartments. As part of the Rule Standard Bilge Pump range, it features a compact, high-efficiency motor with stainless steel shaft and marine-grade blocked wiring for durability in harsh marine environments.

This pump is fully submersible and ignition protected, making it suitable for installation in petrol-powered vessels. It incorporates a snap-lock strainer base for easy cleaning and maintenance access, as well as a vented impeller housing to reduce the risk of airlock. Built-in Thermal Cut-Off (TCO) protection helps safeguard both pump and vessel in case of overload.

The 360–1100 GPH models, including the 500 GPH version, feature backflow prevention to help reduce water returning into the bilge from the discharge line. The Rule 25DA is supplied as a standalone pump; automatic operation requires a separate float switch or panel switch. The pump meets or exceeds CE and ISO 8849 standards and is NMMA listed.
