Description
When you’re dealing with a leaky diaphragm pump on your sprayer or chemical applicator, it’s usually not the whole pump that’s gone bad—it’s the seals. A dripping pump wastes expensive chemicals, creates uneven application, and can turn a straightforward field operation into a frustrating mess. This handy O-ring kit gets you back to reliable sealing without the expense of a complete pump replacement.
What You’re Getting
- Complete set of precision O-rings designed specifically for AR Pumps diaphragm pumps
- Durable rubber compounds that resist chemical breakdown from herbicides and fertilizers
- Quality seals that maintain proper pressure for consistent flow rates
- Direct replacement parts that fit exactly like the originals
Built for Chemical Application Work
This seal kit fits AR Pumps diaphragm models commonly found on field sprayers, tank mixers, and chemical transfer systems. Whether you’re running a pull-behind sprayer for weed control or a nurse tank setup for applying liquid fertilizer, these pumps see regular use in demanding agricultural applications where reliable sealing is critical.
Made to Handle Farm Chemicals
Agricultural chemicals are tough on seals, but these O-rings are manufactured from compounds specifically chosen to resist swelling, cracking, and degradation from common herbicides, fungicides, and liquid fertilizers. The precision fit ensures proper compression without over-stressing the seal, which extends service life even in harsh chemical environments.
Installation Notes
Before installing new seals, clean all sealing surfaces thoroughly and inspect for nicks or scratches that could cause premature failure. A light coat of compatible lubricant helps prevent tearing during assembly. While you’ve got the pump apart, it’s a good time to check valve operation and clean any debris from the pump head.
