SEAFLO 22-Series 12V Water Pump — 1.3 GPM, 100 PSI | Marine, RV & Off-Grid

Overview

The SEAFLO 22-Series 12V water pump is a compact, on‑demand diaphragm pump designed to deliver steady water pressure in tight spaces. With an open flow of 1.3 GPM (5.3 LPM) and a shut‑off pressure up to 100 PSI (6.9 BAR), it supports reliable water delivery when you open a tap, spray, or valve.

Its self‑priming capability draws water from sources up to 6 feet (1.8 m) below the pump, offering flexible placement in boats, RVs, off‑grid cabins, or portable systems. An internal bypass helps maintain consistent pressure, reducing cycling across multiple outlets, while the design allows the pump to run dry without damage, adding tolerance for unexpected water availability during unattended operations.
