About Marine Pumps

Pumps

An extensive lineup of marine pumps is available today from Defender Marine. Pump applications include plumbing, mechanical, and safety pumps plus a full selection of parts and marine pump switches. From marine bilge pumps to oil extractors, our selection is unmatched!

Why so many pumps?

Water is a great source of power and boats, in the loosest terms, tame that power. Marine pumps enable your boat to bring water safely into cool engines and motors. Pumps filter and grind on board fluids before they push them overboard or into holding tanks. Pumps move fluids from one component to another and from here to there within a closed environment like an engine.

Pump it up!

Defender offers a full selection of plumbing pumps to include foot pumps and electric freshwater pumps, sump and gray water pumps for the shower and macerator pumps down below. Mechanical pumps support water cooler engines and air conditioner circulation, fuel pumps for many diesel engine types, and even engine oil change pumps. Fishermen are never left out at Defender as we offer a superior choice of Livewell pumps and freshwater washdown options for the cockpit.

Is it legal?

The US Coast Guard has minimal outlines for boat safety, of course. But did you know that one of those safety outlines is just about boat bilge pumps? Boats are always taking on water - rainwater, seepage or even a wave over the bow all add to water in the bilge which can eventually sink your best girl. Safety pumps at Defender meet the USCG standards - automatic marine bilge pumps, handheld pumps, and fixed electric pumps add up to following the law while you're on the water.
