Rigorous engineering and testing helped generate the new series of bilge pumps. Our pumps are tested to the highest standard, achieving rated performance at 12V vs. 13.6V, resulting in higher flow with better efficiency for the toughest applications. Our new designs include: Higher Flow optimized impeller to provide greater flow at the same amperage. Built-in Thermal Cut-Off (TCO) provides added protection for pump and vessel. Back Flow Prevention - reduces the amount of water left over in the bilge, reducing odor and helping keep your bilge cleaner. Hidden Air Vents in the Body helps prevent air locking in challenging plumbing installations and helps with the check valve. Threaded Discharge - easier installation, easier maintenance. 1" &1 1/8" Hose diameter.
