The Rule Submersible Bilge Pump Range provides reliable and efficient bilge water removal for small and medium vessels. Available in four variants – 360GPH, 500GPH, 800GPH, and 1100GPH – these 12V DC pumps are lightweight, compact, and designed with a tough plastic body, integral strainer, and threaded discharge for easy installation and maintenance. Most models include integrated or compatible float switch options for automatic operation.

Product Description

The Rule Submersible Bilge Pump Range is engineered to meet the diverse needs of boat owners, from small ski boats to larger leisure craft. Each pump in the range is compact, lightweight, and constructed from durable plastic, ensuring reliable operation in challenging marine environments. The integral strainer prevents debris from clogging the pump, while the quick-release design on most models allows rapid cleaning of internal components.

The 360GPH model is ideal for small vessels, delivering up to 23 litres per minute (5 gallons per minute) with a compact footprint and low amp draw, conserving battery power. The 500GPH variant increases flow while maintaining efficient energy consumption, suitable for medium-sized boats. The 800GPH (20DA) model provides up to 50 litres per minute (13 gallons) and incorporates a built-in thermal cut-off, check valve for backflow prevention, hidden air vents to reduce air-locking, and threaded discharge for easier installation. The 1100GPH variant is the highest-capacity pump in the range, designed for vessels with higher bilge volumes while maintaining the same durable construction and safety features.

All pumps are designed for discharge heads of up to 2 metres and are ignition-protected, meeting ISO8846 (marine ignition) and ISO8849 (bilge pump) standards, ensuring safety and compliance. The pumps’ compact designs and lightweight construction make them easy to install in limited spaces, while their energy-efficient operation minimises battery consumption. The range accommodates both manual operation and automatic activation through compatible float switches (depending on model).

Whether upgrading from older pumps or specifying new installations, the Rule Submersible Bilge Pump Range offers reliable performance, durability, and easy maintenance, making them a trusted choice for boat owners and professionals alike.
