Shurflo by Pentair Pre-Pressurized Accumulator Tank - 24 oz.

The Shurflo by Pentair Pre-Pressurized Accumulator Tank – 24 oz. is an essential component for any marine water system, whether you're running a freshwater supply aboard a cruising sailboat, center console, or expedition vessel. This accumulator serves as a pressure buffer that reduces pump cycling and extends the operational life of your onboard water pump.

If you've spent time on the water relying on pressurized water systems, you know that constant pump engagement drains batteries and creates noise—problems this tank elegantly solves. Pre-pressurized accumulators work by storing water under slight pressure, allowing your pump to cycle less frequently while maintaining consistent water pressure at your galley, head, and shower fixtures. The 24-ounce capacity strikes an ideal balance for vessels where space is premium but demand is moderate to steady.

Shurflo by Pentair's design uses a sealed bladder system that prevents air and water from mixing, ensuring stable pressure curves and reliable performance even during extended cruising or anchoring. The compact 6 x 5 x 11-inch footprint and modest weight make installation feasible in tight engine rooms, lazarettes, or under-sink cabins. This accumulator tank is ideal for boat owners who want to reduce electrical load, minimize pump noise, and stabilize pressure fluctuations in their marine water systems.
