Thanks to the built-in pressure switch, it operates fully automatically: the pump starts when a faucet is opened and stops once it is closed. This eliminates the need for a pressure vessel or accumulator tank, and multiple taps can be fed simultaneously.<\/p>\n<p>The high-quality internal materials, such as EPDM valves and a Santoprene diaphragm, ensure a long lifespan and reliable performance in both fresh and saltwater. Thanks to the Quick-Attach connections and standard mounting pattern, installation is quick and easy.<\/p>\n<p>This 24V diaphragm pump is ideal for installations where stable water pressure, quiet operation, and reliability are essential \u2014 perfect for modern onboard water systems without a pressure tank.<\/p>\n<p><strong>Key Benefits<\/strong><\/p>\n<ul>\n<li>Powerful 24V diaphragm pump for pressure water systems<\/li>\n<li>Capacity: 18.9 L\/min<\/li>\n<li>Automatic pressure switch (on-demand operation)<\/li>\n<li>Self-priming up to 1.8 m<\/li>\n<li>Dry-run resistant design<\/li>\n<li>Very quiet operation<\/li>\n<li>Suitable for both fresh and saltwater<\/li>\n<li>Feeds multiple taps simultaneously<\/li>\n<li>Heavy-duty motor and construction<\/li>\n<li>Quick installation with Quick Connect fittings<\/li>\n<\/ul>\n<p><strong>Technical Specifications \u2013 24V Model<\/strong><\/p>\n<ul>\n<li>Model: SFDP2-050-070-52<\/li>\n<li>Voltage: 24V<\/li>\n<li>Capacity: 5.0 GPM \/ 18.9 L\/min<\/li>\n<li>Max. current draw: 10.0A<\/li>\n<li>Pressure cut-off: 70 PSI \/ 4.8 bar<\/li>\n<li>Self-priming: 1.8 m<\/li>\n<li>Max. temperature: 60\u00b0C<\/li>\n<li>Connections: Quick Attach<\/li>\n<li>Valve material: EPDM<\/li>\n<li>Diaphragm: Santoprene<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The SEAFLO 24V drinking water pump diaphragm pump is a powerful and reliable water pressure pump for pressurized water systems onboard boats, campers, and off-grid installations.
