Bilge Pump Systems

Bilge pump systems are a critical safety component for any vessel, designed to remove water that collects in the hull. A complete system typically includes the pump, a switch (automatic or manual), and discharge plumbing.

Types of Bilge Pump Systems

Choosing the right system depends on your boat's size and whether it is left unattended at a dock.

• Automatic Systems: These use an internal or external float switch to detect water. They are essential for boats kept in the water, as they can prevent sinking from rain or small leaks while you are away.

• Non-Automatic Systems: These are activated by a manual switch at the helm. They are simpler and often used as high-capacity secondary pumps for emergencies.

• Manual Hand Pumps: These require no electrical power and serve as the ultimate backup if your batteries fail or the engine room floods.

Top Automatic Bilge Pumps

For standard 12V systems, these integrated units are popular for their ease of installation and reliability.

• The Rule Rule-Mate 800 is a highly-rated fully automated pump that moves 800 GPH. It is known for its solid performance and is a common replacement for older units.

• The Attwood Sahara MK2 features a patented X-Air Impeller designed to eliminate air locks, ensuring the pump doesn't run dry and burn out in choppy conditions.

• For higher capacity, the Rule 2000 GPH Automatic uses computerized sensing rather than a mechanical float, making it ideal for deep keel sumps and hard-to-reach areas.

Manual & Emergency Backup Pumps

Every boat should have a manual backup to handle water removal if the electrical system fails.

Essential Float Switches

If you have a non-automatic pump, you can convert it to automatic operation with an external switch.
