Description
When your sprayer isn’t building pressure like it used to or you notice chemical seeping around pump seals, it’s time to rebuild that diaphragm pump. A worn pump kit can turn a quick spray job into a frustrating day of poor coverage and wasted chemicals. This complete service kit gets your AR pump running like new again, so you can get back to protecting your crops with confidence.
What You’re Getting
- Complete set of diaphragms, valves, and O-rings for a thorough pump rebuild
- High-quality materials that resist chemical damage and hold up to farm use
- Everything needed for proper pressure and flow restoration
- Direct replacement parts engineered to AR Pumps specifications
Built for Real Farm Work
AR pumps are found on sprayers across farm country, from small ATV units for spot spraying to large field sprayers covering hundreds of acres. Whether you’re applying herbicides in the spring, fungicides during the growing season, or cleaning up fence rows, your pump needs to deliver consistent pressure and accurate chemical metering for effective coverage.
Made to Last
Farm chemicals are tough on pump components, but this kit uses materials designed to handle the job. The diaphragms resist stretching and cracking, while seals and valves maintain their integrity through temperature changes and chemical exposure. Quality construction means fewer rebuilds and more reliable spraying seasons.
Installation Notes
Take photos before disassembly to help with reassembly, and clean all surfaces thoroughly before installing new parts. Check valve seats for damage while you have things apart – a scratched seat can cause the new kit to leak. Having a clean workspace and good lighting makes the job go much smoother.
