If your sprayer’s not building pressure like it used to or you’re seeing chemicals seeping where they shouldn’t, it’s probably time to rebuild those diaphragms. A failing diaphragm pump can turn a straightforward spraying job into a frustrating day of uneven coverage and wasted chemicals. This repair kit gets your AR pump back to full pressure and reliable operation.
What You’re Getting
- Complete Desmopan diaphragm set – this synthetic material holds up better than rubber against agricultural chemicals
- All the seals and O-rings you need for a proper rebuild job
- Everything’s sized right for AR medium pressure pumps – no guessing or measuring required
- Quality components that match the original pump specifications
Built for Real Farm Work
This kit works with AR diaphragm pumps commonly found on pull-type sprayers, three-point sprayers, and spray rigs used for crop protection and field applications. Whether you’re applying herbicides, fungicides, or liquid fertilizer, these pumps see plenty of action during spray season.
Made to Last
Desmopan material resists the harsh chemicals that would eat through standard rubber diaphragms in a season or two. It stays flexible in cold weather and won’t swell or crack when exposed to different spray chemicals. The seals are made to handle the pressure cycles and chemical exposure that come with serious spraying work.
Installation Notes
This is a straightforward rebuild if you’re handy with tools – most folks can knock it out in an hour or so. Clean everything thoroughly before assembly, and don’t forget to lubricate the seals during installation. Check your pump manual for proper torque specs on the diaphragm housing bolts.
