Description
When you’re out controlling weeds along fence lines or spot-treating problem areas in the pasture, you need a pump that starts reliably and delivers steady pressure. This Shurflo 12-volt diaphragm pump is built for exactly those jobs—delivering 4 gallons per minute at 45 PSI with the bypass feature that automatically regulates pressure without overworking the pump.
What You’re Getting
- Steady 4.0 GPM flow rate that’s perfect for handheld spray guns and small boom applications
- Built-in bypass system that prevents pump damage when the spray gun is shut off
- Durable Santoprene diaphragm and valves that handle agricultural chemicals without breaking down
- Standard 1/2-inch NPT male ports that connect easily to your existing spray setup
- 12-volt operation that works with any farm vehicle’s electrical system
Built for Real Farm Work
This pump is designed for spot spraying applications where you need portable, reliable chemical application. Whether you’re mounted on an ATV, UTV, or pickup truck, the compact design and electrical connection make it easy to set up a mobile spray rig for tackling weeds, treating fence rows, or applying chemicals to specific problem areas around the farm.
Made to Last
This pump is designed to handle the vibration, dust, and temperature extremes that come with agricultural work. The Santoprene materials resist chemical breakdown and the self-priming design means you don’t have to worry about losing prime when the tank runs low or when you’re working on uneven ground.
Installation Notes
The 1/2-inch NPT threads fit standard agricultural spray fittings, and the 12-volt draw works with most farm vehicle electrical systems. Mount it securely since the diaphragm design creates some vibration, and always use a fuse or breaker to protect your electrical system. The bypass feature means you can leave the pump running even when you’re not actively spraying.
