Built for Real Farm Work
This kit works with AR Pumps diaphragm pumps commonly found on field sprayers, spot sprayers, and boom applicators. Whether you’re applying herbicides in the spring, fungicides during growing season, or cleaning up fence rows in the fall, a properly functioning pump is essential for accurate application rates and coverage.
Made to Last
Agricultural pumps take a beating from chemical exposure, temperature swings, and constant pressure changes. This kit uses materials that resist degradation from common farm chemicals and maintain their seal under the pressure cycling that’s part of everyday spraying operations.
Good to Know
Before tearing into the pump, make sure you’ve got a clean workspace and new pump oil on hand. It’s also worth checking the diaphragms while you’ve got everything apart – worn valves and worn diaphragms often go hand in hand. Keep the old parts until you’re sure the new ones are working right.
