Kaydon K-BOS Oil Seals Improve Performance of Flash Gas Compressors

K-DGS retrofit replacing the oil seals on a natural gas pipeline compressor improves compressor performance while reducing seal maintenance requirements. No modification was required to either the compressor shaft or casing.

Seal retrofit on a Fluid Cat Cracker (FCC) wet gas compressor train delivers significant performance and reliability improvement. The installation also eliminated significant H₂S leakage allowing maintenance staff to operate safely without breathing apparatus. A real win:win solution.

Better than 95% reduction in sour oil leakage on a hydrotreater compressor. Retrofit of bespoke oil seals improves compressor performance. Service flexibility offers best-practice MRO for high-dependency mechanical seals.

When a pressurised double mechanical seal on a vertical pulper began to fail, NASH first inspected and retested the spare seal in under a week, making it available to replace the installed seal before it failed completely and potentially brought the plant to a standstill

NASH seal repair on natural gas pipeline compressor delivers ‘as-new’ performance at a significantly lower cost than seal replacement – and a great platform for ongoing seal MRO

Our partner has a customer using a De Dietrich reactor fitted with a Crane CK738GD seal that needed replacing. However, the spare seal had been on the shelf for 8 years. It needed inspecting, testing and installing within 7 days. The seal OEM could not meet this deadline.

When mechanical seal life averaged only 10 months, with unplanned outages and costly replacements, NASH beat OEM repair prices and turnaround times, while also upgrading carbon faces and improving seal performance for an Eire pharmaceutical manufacturer.

Following initial email consultations, a specialised double seal cartridge experiencing start-up contamination problems in Kuala Lumpur was flown to NASH in the UK for a fast turnaround inspection, failure diagnosis, repair and advice on improved future operation.
