Rule Gold Series 3700 GPH 12V Bilge Pump

The Rule Gold Series 3700 GPH 12V Bilge Pump gives dependable high-capacity bilge-water removal for compatible boats and marine electrical systems. Its submersible centrifugal design places the pump directly in the bilge, allowing water to enter through the strainer and discharge through connected hose when the pump is activated.

The non-automatic pump is intended to operate from a separate switch or control system, allowing the installer to choose the appropriate manual or automatic control arrangement. Rule's anti-airlock design, corrosion protection, and compact motor construction support dependable pumping when the installation is kept clean and electrically sound.

Confirm pump capacity for the boat, electrical supply, fuse or breaker protection, discharge-hose size, mounting location, and control method before installation. Keep the strainer accessible for cleaning and route the discharge hose to minimize restriction and backflow. Explore additional bilge water pumps when planning primary and backup pumping capacity.
