Global expertise in engineered mechanical seals – A unique & compelling proposition
Engineered mechanical seals perform a vital task across a wide range of high-dependency turbomachinery where failure really isn’t an option. Insuring against failure often means turning to the service arms of major seal OEMs where the real-world support experience can leave a great deal to be desired. Typical issues faced by seal end-users include: Slow […]
Oil Seals or Dry Gas Seals – which is best for your application?
Since their development in the 1980s, Dry Gas Seals have become the de-facto standard for rotating shaft sealing applications in centrifugal and screw compressors across the oil and gas sector. However, with gas compressors having operating lives running into several decades, there are still many running with wet lubricated (oil) seals. OEMs have almost universally […]
Seal performance – Top Tips
Getting the best performance from your engineered mechanical seals can be challenging. Mechanical seals have a working life after which they must be re-engineered/repaired or, in the case of smaller/low-cost seals, replaced. With experience across all major mechanical seal brands, NASH has an unrivalled knowledge-base. Seal Performance Top Tips from NASH Here are our top tips to help get the best […]
