The Rule 27DA 1100 Series Submersible Bilge Pump is a high-capacity, compact bilge pump designed for dependable performance in demanding marine environments. With a flow rate of up to 4164 litres per hour (1100 GPH), this 12V pump is ideal for small to medium boats requiring fast and efficient bilge water removal.
Built with a rugged plastic housing, integral quick-release strainer, and a threaded discharge, the Rule 27DA is engineered for easy installation and maintenance. It features backflow prevention, a thermal cut-off (TCO) for overload protection, and hidden air vents to prevent air-locking in complex plumbing setups.
