Questions that improve bespoke mechanical seal services
To guarantee every seal we repair is fit for purpose, we need to check the seal specification is correct for the application, explains NASH’s Geoff Farnworth I would like to apologise in advance for asking you so many questions! However, your answers will help us to diagnose the root cause of any mechanical seal problem, […]
What is a mechanical seal and how does it work?
Mechanical seals are devices that control the leakage of fluid between a rotating shaft and the pressurised casing on rotating equipment. Typical applications include centrifugal pumps, reactors, mixers and compressors. Originally developed to overcome gland packing-type seal limitations, modern seals are designed to reduce emissions and improve rotating equipment performance. Figure 1 (to the right) […]
Are your mechanical seals repaired by an IECEx Certified Service Facility?
NASH is working towards becoming an IECEx Certified Service Facility for the repair of mechanical seals and associated equipment. The certification is based on the requirements of IEC 60079-19 and we plan to be fully certified by Q3 of 2016. IEC 60079-19 is an internationally recognised scheme for the repair of equipment operating in potentially […]
Investing in the future with two new engineering apprentices
In a sector with a widely acknowledged succession challenge, we’re delighted to have been able to take on two apprentices through the Employer Opportunity Programme (EOP) which is linked to the UK government’s SEMPTA programme, benefitting from investment and commitment from British engineering heavyweight BAE. In their first year, our apprentices successfully completed a BTEC […]
