12V Diaphragm Sprayer Replacement Pump with 1–7 GPM Options, Self-Priming Choices and Slide-Lock Hoses - CHAPIN

A 12V diaphragm sprayer replacement pump moves water or compatible lawn and cleaning liquids through ATV, UTV, marine and RV systems. The documented CHAPIN 6-9206 standard model delivers 1 GPM and up to 60 PSI, using chemical-resistant elastomer seals and a universal mounting base. Slide-lock hose connections simplify pump swaps, while an in-line fuse protects the circuit.

The storefront also offers 3, 4, 5 and 7 GPM self-priming models, which have different performance and may not share every documented specification. The source labels the 1 GPM version self-priming in one section but Standard in the variant name; verify priming behavior on the selected model. Use only a properly fused 12V supply despite one conflicting AC field, check liquid compatibility with seals and hoses, mount securely and flush the system according to the chemical manufacturer’s instructions after use.
