Description
When your Hypro roller pump starts losing pressure or the flow isn’t what it used to be, chances are the rollers and seals need attention. This handy repair kit gets your 4001 or 4100 series pump back to running like new, with everything you need to restore proper flow and pressure for another season of reliable spraying.
What You’re Getting
- Four high-quality poly rollers that create the tight seal needed for consistent pressure
- O-ring gasket for the end plate that prevents internal leaks and maintains pump efficiency
- Viton seals that resist chemical damage and temperature extremes better than standard rubber
- Complete rebuild solution in one kit—no hunting around for individual pieces
Built for Real Farm Work
These kits work on Hypro’s popular 4001 and 4100 series roller pumps found on countless sprayers across the country. Whether you’re running a three-point hitch sprayer, pull-type boom, or tank sprayer for pasture work, these are the same quality parts that came in your pump from the factory.
Made to Last
The poly rollers resist wear from agricultural chemicals while maintaining the flexibility needed to seal properly against the pump housing. Viton seals handle the heat and chemical exposure that comes with spray applications, lasting longer than standard rubber seals that can crack or swell when exposed to certain herbicides.
Good to Know
Before you tear into the pump, make sure to drain all the fluid and clean the housing thoroughly. Take a photo of the roller orientation before disassembly—it’ll save you time during reassembly. If your pump has been sitting unused for a while, check the housing for any corrosion that might affect the new seals.
