GROCO Bronze 17 GPM Centrifugal/Baitwell Pump

The GROCO Bronze 17 GPM Centrifugal/Baitwell Pump is a high-volume circulation pump engineered for marine baitwell systems and general onboard pumping applications where consistent, high-GPM flow takes priority over pressure output. Built by GROCO, a trusted name in marine fluid transfer solutions, this pump delivers reliable performance in saltwater and freshwater environments where livewell aeration, bait circulation, and cooling system applications demand robust, dependable operation. Whether you're running a commercial fishing operation, maintaining a recreational fishing vessel, or managing marine ballast requirements, this centrifugal pump provides the flow capacity modern marine systems require.

This bronze pump operates on a 12-volt DC electrical system and uses centrifugal design principles to move water efficiently at 17 gallons per minute—ideal for applications prioritizing volume over pressure differential. The intake features a 3/4-inch NPT threaded inlet, while the discharge outlet is sized at 1/2-inch NPT, allowing flexible plumbing integration with standard marine fittings and hose configurations. Bronze construction throughout the pump body and internal components ensures exceptional corrosion resistance in harsh saltwater conditions, preventing rust and degradation that can compromise performance over extended seasons. The compact footprint—measuring 5 x 5 x 10 inches and weighing just 5.5 pounds—enables straightforward installation in tight engine compartments or mounting locations without requiring substantial structural modifications.

Boaters, charter captains, and marine system integrators benefit most from this pump's straightforward installation and low-pressure reliability. The 12-volt DC operation makes it compatible with standard marine electrical systems, and the NPT thread configuration simplifies plumbing hookup to existing through-hulls, manifolds, and circulation lines. Installation typically requires securing the pump to a stable mounting surface with access to a 12-volt power source and appropriately sized intake and discharge hoses—no special tools or proprietary adapters needed. This pump excels in baitwell applications where constant circulation keeps bait alive and responsive, and performs equally well in raw-water cooling loops, bilge circulation, or wash-down systems where dependable, corrosion-resistant operation is non-negotiable.
