Description
When your AR Pumps diaphragm pump starts losing pressure or acting up, it’s usually the diaphragm that’s taken a beating. Between the chemicals you’re spraying and the constant flexing during operation, even the toughest diaphragms eventually wear out. That’s where this Desmopan diaphragm kit comes in—it’s specifically designed to handle the harsh conditions of agricultural and chemical pumping applications.
What You’re Getting
- High-grade Desmopan material that resists oils, greases, and chemical solvents better than standard rubber
- Superior wear resistance that means fewer pump rebuilds and less downtime during busy seasons
- Proven chemical compatibility with herbicides, fertilizers, and other farm chemicals you’re likely to pump
- Direct fit replacement components that restore your pump’s original performance
Built for Real Farm Work
This kit is made for AR Pumps’ medium pressure diaphragm systems that power sprayers, chemical applicators, and wash systems across thousands of farms. Whether you’re applying herbicides, liquid fertilizer, or washing down equipment, these pumps see plenty of action during spray season and need components that can keep up.
Made to Last
Desmopan isn’t your typical diaphragm material—it’s an engineered thermoplastic that handles chemical exposure and temperature swings better than standard rubber compounds. This means your pump keeps its seal and maintains pressure even when you’re running aggressive chemicals or working in extreme weather conditions.
Good to Know
Before tearing into your pump, make sure you’ve got fresh gaskets and seals on hand—it’s smart to replace everything while you’re in there. Clean all the pump surfaces thoroughly and check for any scoring or damage that might cause the new diaphragm to fail prematurely.
