Description

Whether you’re spot-treating weeds in the pasture or laying down pesticide along fence rows, having a reliable pump that starts when you squeeze the trigger and stops when you let go makes all the difference. This 12-volt diaphragm pump with demand switch takes the guesswork out of spraying by automatically cycling on and off based on pressure demand, so you can focus on hitting your targets instead of fiddling with switches.

What You’re Getting

Automatic demand switch that starts the pump when you trigger your spray gun and shuts off when you stop
3.0 GPM flow rate provides solid coverage without wasting chemical or battery power
45 PSI operating pressure gives you good spray pattern and penetration for most herbicides and pesticides
Viton valves and Santoprene diaphragm handle most agricultural chemicals without breaking down
1/2-inch NPT male ports fit standard spray system fittings and hoses

Built for Real Farm Work

This pump is designed for ATV-mounted sprayers, small tank applications, and spot treatment rigs where you need reliable chemical delivery without the bulk of a PTO-driven system. Perfect for treating problem weeds, applying herbicide around buildings and fence lines, or any time you need precise chemical application in smaller areas.

Made to Last

The Viton valve materials resist chemical breakdown from most common herbicides and pesticides, while the Santoprene diaphragm stays flexible through temperature changes and repeated cycling. Shurflo builds these pumps to handle the vibration and abuse that comes with bouncing around on ATVs and utility vehicles.

Installation Notes

Wire the pump to a fused 12-volt power source and plumb it between your tank and spray gun. The demand switch senses pressure drop when you open your nozzle and automatically starts the pump. Keep electrical connections clean and dry, and consider mounting the pump where it’s protected from direct spray contact.
