Description
When your pump starts leaking around the shaft or losing prime more often than it should, chances are it’s time to replace that mechanical seal. A worn seal not only wastes whatever you’re pumping but can damage expensive pump components if you keep running it. This Viton seal is built to handle the tough conditions your Ace pump sees every day.
What You’re Getting
- Heavy-duty Viton construction that stands up to chemicals, heat, and constant use
- Complete mechanical seal assembly with included O-ring for a proper installation
- Carbon and ceramic seal faces that create a reliable, long-lasting seal
- Direct replacement that fits without modifications or adjustments
Built for Real Farm Work
This seal works in Ace FMC, FMCHYD, and PTOC series centrifugal pumps—the workhorses you’ll find on sprayers, liquid fertilizer applicators, and other equipment where you need reliable fluid transfer. Whether you’re pumping water, liquid fertilizer, or crop protection products, this seal keeps everything contained where it belongs.
Made to Last
Viton rubber is the go-to material when you need a seal that won’t quit. It handles temperature swings, resists chemicals that would eat up regular rubber, and keeps its flexibility season after season. The carbon and ceramic seal faces are self-lubricating and won’t score or wear like cheaper alternatives.
Good to Know
Make sure to clean the seal housing thoroughly before installing the new seal, and check that the shaft isn’t scored or damaged. A little clean grease on the O-ring helps it seat properly. If you’ve been dealing with seal problems, it’s worth checking your pump alignment and making sure you’re not running it dry.
