SEAFLO 22-Series 12V Water Pump — 1.3 GPM, 100 PSI | On-Demand Diaphragm Pump

Overview

The SEAFLO 22-Series 12V water pump delivers on-demand pressure for marine, recreational, and off-grid water systems. This compact diaphragm pump moves water with a steady 1.3 GPM flow and a 100 PSI shut-off, offering reliable performance in a range of environments where power, space, and efficiency matter.

Smart, on-demand operation

Equipped with a built-in pressure switch, the unit starts when water is needed and stops when flow drops, helping conserve energy and water. An internal bypass maintains consistent pressure across multiple outlets, reducing unnecessary cycling and contributing to smoother operation over time.

Self-priming and durable design

• Self-priming capability up to 6 feet (1.8 m) ensures reliable water delivery even when the source is a bit above the pump.
• Can run dry without damage, offering a forgiving performance in low-water conditions or unmonitored use.
• EPDM valves and a Santoprene diaphragm provide a sturdy, long-lasting build that holds up under varied temperatures and conditions.
