Freshwater Delivery Pumps -
Installed to provide on-demand flow and pressure of freshwater to galleys, showers, washing machines, etc. Typical rule of thumb for sizing is 1 GPM per outlet. 40-60 psi (2.8 - 4.1 Bar) options provide similar pressure to that in a home on land. These pumps are equipped with a bypass which enables smoother flow and decreases cycling. Common accessories include strainers, water pressure inlet regulators, and accumulator tanks.

Washdown -
Used for on-demand spray to clean anchors, buoys, fishing areas, etc. Typically, the higher the flow and the higher the pressure the better. Sometimes used with a Y valve to serve a dual purpose of livewell circulation. Common accessories include strainers, trigger nozzles, hoses, and deck mount fittings. Sometimes plumbed off of the livewell inlet to reduce number of thru-hull fittings.

Shower-Drain/Livewell/General Purpose -
These pumps are configured without a pressure switch and are used for a variety of different purposes including
removal of drain water from showers or the circulating/transfer of water in bait tanks.
