Description

When you’re spraying crops or applying liquid fertilizer, the diaphragm is the heart of your spray pump system. This Desmopan diaphragm is what actually moves the chemical through your sprayer, and when it wears out or tears, your whole operation comes to a halt. Made from durable Desmopan material, this replacement diaphragm gets your AR pump back to delivering consistent pressure and flow rates you can count on.

What You’re Getting

High-quality Desmopan material that resists chemical breakdown from herbicides and fertilizers
Precise fit for reliable pumping action without leaks or pressure loss
Engineered flexibility that handles thousands of pump cycles without cracking
Chemical resistance that stands up to the harsh products you’re applying

Built for Real Farm Work

This diaphragm fits AR pump systems commonly found on field sprayers, pull-behind applicators, and liquid fertilizer equipment. Whether you’re running a three-point sprayer on your utility tractor or operating a self-propelled applicator, AR pumps are workhorses in agricultural chemical application. These pumps handle everything from post-emergence herbicides to liquid nitrogen, and they depend on quality diaphragms to maintain proper flow and pressure.

Made to Last

Desmopan is specifically chosen for agricultural pump applications because it resists the chemicals that would destroy standard rubber diaphragms. This material maintains its flexibility through temperature swings and chemical exposure, giving you reliable service season after season. The precise manufacturing ensures proper sealing and consistent pump performance.

Installation Notes

Replacing a diaphragm usually means disassembling the pump head, so it’s a good time to inspect valves and seals while you’re in there. Make sure the diaphragm seats properly in its housing – any wrinkles or folds will cause premature failure. Clean all surfaces thoroughly before reassembly, and check your pump manual for proper torque specifications on the head bolts.
