When your sprayer pump starts losing pressure or flow, worn rollers are usually the culprit. These little workhorses inside your Hypro pump take a beating from chemicals, debris, and constant pressure changes, and eventually they’ll start showing their age. Fresh rollers can bring your pump back to like-new performance and save you from having to replace the whole unit.
What You’re Getting
- Genuine Hypro super rollers designed for reliable sealing and smooth operation
- Durable construction that handles the pressure and chemical exposure of ag spraying
- Complete set of 4 rollers—exactly what your 4001 or 4101 pump needs for a full rebuild
- Perfect fit that restores proper clearances and pump efficiency
Built for Real Farm Work
These rollers are made for the 4001 and 4101 series pumps that are popular on smaller sprayers and ATV units. The 4101 series pumps are built for direct gas engine drive at speeds up to 2600 RPM with 7.2 GPM flow and 150 PSI pressure ratings. Whether you’re running a three-point sprayer, pull-behind unit, or spot spraying setup, these pumps see plenty of action during spray season.
Made to Last
Hypro knows their pumps end up in tough conditions, so these super rollers are built accordingly. The material resists swelling from chemical exposure and maintains its shape under pressure. When installed properly, they’ll give you seasons of reliable service before needing replacement again.
Good to Know
You’ll need all 4 rollers for a complete repair—don’t try to get by with replacing just one or two worn ones. While you’ve got the pump apart, it’s a good time to inspect the cam ring and housing for wear. A little assembly grease on the rollers during installation helps them seat properly and extends their life.
