A pharmaceutical company based in Ireland had several Goulds STX pumps fitted with John Crane T2800E/0349 pressurised double gas lubricated mechanical seal cartridges. The pumps operate at 2900 rpm and the product temperature is ambient. Barrier gas is nitrogen.
Client challenge:
The company was looking for a more responsive service and higher quality seal repairs to avoid unplanned outages and the associated lost production caused by premature failure of their mechanical seals.
Our response:
Working to original seal specifications and materials, NASH independently specified and sourced all necessary seal parts, including laser-etched faces, and began repairing and rebuilding each seal cartridge in factory-controlled conditions. Each seal was also dynamically tested at pump operating parameters to verify performance prior to shipping.
Client benefits:
-
- Fewer seal failures
- Improved seal performance
- Reassurance of factory dynamic test
- Increased pump operating times
- Lost production eliminated
NASH helped the pharmaceutical company meet its pump operational objectives. If you operate pumps with unreliable mechanical seals and need a solution, please to contact us.
