Our bilge pumps provide ultimate pumping performance, which helps keep your bilge clear of nuisance water, building on the genuine Rule design. Rigorous engineering and testing helped generate the DA 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. Higher Flow optimized impeller to provide greater flow at the same amperageBuilt-in Thermal Cut-Off (TCO) provides added protection for pump and vesselBack Flow Prevention reduces the amount of water left over in the bilge, reducing odor and helping keep your bilge cleanerHidden Air Vents in the Body helps prevent air locking in challenging plumbing installations and helps with the check valveThreaded Discharge easier installation, easier maintenance
