Description
The Rule 1100 GPH Auto Sensing Pump 12V (27SA) combines strong output with fully automatic operation to provide serious bilge protection for a wide range of boats. Built from tough plastic with easily replaceable dirt filters, it is designed to survive day to day life in the bilge while keeping water levels under control. An integrated electric float switch and control circuit briefly energize the pump every two and a half minutes to check for water, so the system can react automatically without a separate external float switch.
- Automatic 1100 GPH submersible bilge pump designed for demanding marine use.
- Operates on 12V DC, making it suitable for most recreational and light commercial vessels.
- Uses an integrated float and electronic sensing that turn the pump on for a short period every 2.5 minutes to test for water.
- If water is present, the pump continues to run and clears the bilge quickly with high output around 70 litres per minute.
- Sturdy plastic housing resists impact and corrosion for long service life in harsh bilge environments.
- Easily replaceable dirt filters help keep debris from entering the pump and can be changed or cleaned with minimal effort.
- Auto sensing design removes the need for a separate float switch and simplifies wiring and installation.
- High flow capability makes this pump suitable as a primary unit on many small to midsize boats.
- Can also serve as a backup or emergency pump on larger craft where extra capacity is important.
- Compact, submersible form factor lets you mount it where space is tight yet reliable drainage is needed.
- Compatible with typical marine panel switches and fusing when installed according to manufacturer guidelines.
Boaters who want a powerful yet compact automatic bilge pump with integrated sensing and solid flow performance will find the Rule 1100 GPH Auto Sensing 27SA pump a dependable addition to their bilge system.
