Built for Real Farm Work
The Hypro 9028c-0 is a workhorse diaphragm pump found on many agricultural sprayers, from smaller boom sprayers to bigger field units. Whether you’re spraying herbicide on corn, applying fungicide to soybeans, or spot-treating pastures, this pump handles the chemicals and pressure demands of modern farming. This repair kit keeps it running season after season.
Made to Last
Farm chemicals are tough on pump components, but these seals are built to handle the punishment. The materials resist swelling and deterioration from constant exposure to herbicides, insecticides, and other ag chemicals. Quality construction means fewer breakdowns during critical spraying windows.
Installation Notes
This is a complete rebuild kit, so plan on taking the pump apart and replacing all the seals while you’re at it. It’s worth cleaning all the pump surfaces thoroughly before reassembly. A thin coat of compatible grease on the O-rings helps them seat properly and extends their life.
