SEAFLO 22-Series 12V Water Pressure Pump 1.3 GPM, 100 PSI, On-Demand Diaphragm Pump The SEAFLO 22-Series 12V Diaphragm Pump is a compact, high-pressure on-demand freshwater pump engineered for small to mid-sized marine, RV, agricultural, and off-grid applications. With a flow rate of 1.3 GPM and a maximum pressure of 100 PSI, this pump is designed for systems requiring strong pressure output in a small footprint. It is ideal for sprayers, misting systems, compact freshwater lines, and general utility water transfer. This model features an automatic pressure switch that activates the pump when system pressure drops and shuts it off at 100 PSI, delivering efficient on-demand performance without cycling issues. The 3-chamber diaphragm design provides consistent flow, while the sealed motor and corrosion-resistant internal components ensure long-term durability in harsh environments. Self-priming capability allows the pump to be installed above the water source, making it versatile for a wide range of plumbing layouts. Compact, energy-efficient, and built to handle demanding duty cycles, the SFDP1-013-100-22 is well-suited for marine freshwater accessories, RV cleaning attachments, agricultural sprayers, and off-grid systems where high pressure and reliable operation are essential.
