Built for Real Farm Work
This pump shines in field sprayer applications where you need consistent pressure and flow. Whether you’re running a 3-point sprayer behind your tractor, setting up a pull-type unit, or building a custom spray rig, this pump handles the chemical mixes that protect your crops. It’s designed for the temperature swings and vibration that come with outdoor equipment.
Made to Last
Diaphragm pumps are the go-to choice for chemical applications because they don’t have seals that get eaten up by herbicides and pesticides. The twin diaphragm design keeps flow smooth even if one side needs service. AR builds these pumps to handle the demanding duty cycle of agricultural spraying where reliability can’t take a back seat.
Installation Notes
The included AR1671 gearbox makes engine mounting straightforward—just match it up with your gas engine’s output shaft. Check your chemical compatibility charts before filling the tank, and remember that diaphragm pumps work best with some back-pressure, so don’t run them completely open.
