12V Sprayer Pump, 2.5gpm-8amp-60psi, Chemical and Corrosion Resistant, Compatible with Roundup, Diaphragm

This 12V diaphragm sprayer pump is designed to handle fluid transfer and pressure spraying across agricultural, marine, and home settings. Running on an 8-amp draw, it delivers a maximum flow rate of 2.5 gallons per minute and allows you to adjust output pressure between 0 and 60 PSI. It fits practical setups ranging from farm spraying and garden irrigation to RVs, boats, soft wash rigs, and household water supplies.

Built with an all-copper motor and an integrated leak-proof structure, the unit incorporates a chemical- and corrosion-resistant diaphragm. This internal design allows it to work with various liquids, including bleach, fresh water, and Roundup. The pump features an automatic shutoff mechanism, along with internal overheat protection that halts operation to cool down before restarting automatically. A rubber mounting base is included to provide quiet, stable operation during extended use.

For plumbing and installation flexibility, the pump offers self-priming capability up to 10 feet and can achieve a lift head of up to 114 feet. It comes packaged with both 1/2-inch and 3/4-inch hose adapters to fit common line sizes, and it includes a built-in inlet filter to keep debris and impurities from entering the diaphragm chamber.

As with most pressure-switch pumps, keeping your inlet and outlet flow balanced is essential. If the flow is restricted or mismatched, the pump can experience frequent switch cycling, which can cause premature wear over time. Operating this unit also requires a dedicated 12-volt power supply capable of sustaining an 8-amp current draw.

Verdict: This pump is a dependable choice for homeowners, gardeners, and equipment owners who need a versatile 12-volt sprayer for bleach, weed killer, or general water transfer. Its adjustable pressure, self-priming lift, and included fittings make it an easy upgrade for small-to-midsize spraying systems.
