3700 GPH Submersible Bilge Pump by Rule

The Rule 3700 GPH Heavy Duty Bilge Pumpis designed for both commercial and civilian boat and pumpage applications and is one of our most powerful pumps! With a larger 1 and 1/2 inch (38mm) discharge outlet, this 12 volt DC pump is fully submersible in water and runs at almost 100 degrees F cooler than most other submersible pumps to ensure a longer life. With a nylon/fiberglass impeller, a heavy 5/26th inch stainless steel shaft housed inside heat resistant acetal resin, this heavy duty pump will get the job done.

Known for its reliability, the Rule 3700 GPH Heavy Duty Submersible Bilge Pumps stands at 7.3 inches height x 4.9 inches depth x 4.9 inches width. Non-automatic, please not that this pump uses a 1 and 1/2 inch house outlet, slightly larger than the standard size.
