Chesterton® 11K Rod Seal Gets the Job Done in Steel Mill
Intro
Case study APAC0029 – Chesterton products – Chesterton EPS
A client working in a steel mill was dealing with a plunger pump experiencing frequent leakage caused by an unbalanced load. Their solution had to be resistant to high temperatures, therefore reducing downtime for repairs and replacement. Chesterton suggested a solution created with the Chesterton® 11K Rod Seal and Chesterton® 19K Split Wear Rings, and the replacement cycle has now extended.
