Why this pump stands out

• 60 PSI, 18.9 L/min output ensures strong showers, powerful washdowns, and consistent galley tap pressure for comfortable everyday use.
• Built-in pressure switch kicks the pump on and off automatically with taps, reducing water waste and eliminating manual control.
• Automatic start/stop behavior keeps output steady when you open or close outlets, delivering immediate pressure where it’s needed.
• Large displacement diaphragm chamber supports multiple outlets without an accumulator tank, simplifying installation and reducing system complexity.
• Self-priming up to 2.4 meters— ideal for mounting above water tanks or in tight engine rooms where gravity feed isn’t guaranteed.

• Self-contained strainers and filters help protect the pump from debris and prolong life in demanding environments.
• 12V operation with overload protection and a thermal cut-out to guard against overheating during long washes or high-demand cycles.
