Mechanical Seal Reconditioning 

Henry R. Ayton provides wide-ranging solutions to meet your company’s requirements for seal maintenance and performance monitoring of pumps, mixers, agitators etc.

- Set pricing refurbishments –Where we would offer a 3 or 5 stage price for refurbished seals and pumps based on an agreed level of work required. 

- Service Exchange –Where available we can offer a refurbished John Crane cartridge seal in place of a competitors seal at a fraction of the cost of a new seal. 

- Seal management contracts – Where we will carry out a site survey of pumps and vessels, check installation, check leakage, re-fill thermosyphons, repair/replace mechanical seal if required and issue report with recommendations if required.

- Seal reliability contracts – Where we chart all seal failures on the John Crane Interface database which is made available for clients to view at any time via personal password, where the opportunity to view failure reports and seal/pump failure history is available which also allows HRA to issue reports on bad performing seals/pumps at set time scales eg 3-6-12 month intervals.

- Condition Monitoring – Where a 3-1 wireless transmitting node is attached to either all pumps or only the critical pumps via the thermosyphons where a signal is sent to visual output where it tracks level, pressure and temperature. This can be integrated into a client’s internal management system or alternatively a HRA representative can come to site either bi-weekly weekly or monthly to monitor and offer recommendations on pump performance.

- Seal Training – Where a tailored training package can be assembled and presented to key personal at either our facility or at the clients site. Also if required we can call on the support of John Crane UK & John Crane Europe for specialised in-depth aspects of a training plan.

Henry R. Ayton have for many years provided a full mechanical seal refurbishment service from our Cork Service Centre where seals after removal, either through plant maintenance, normal use or seal failure, are returned for refurbishment at a fraction of the cost of a new product. This involves the cleaning and inspection of the incoming parts to determine the extent of the work to be performed and to identify which components need replacement. On receipt of approval from the customer our technicians perform the work necessary to return the product to “like new” condition, using only OEM materials and work procedures. All seals are tested and certified prior to dispatch. Each unit has its own unique identification code which allows for full traceability. Also, if required a full engineering report can be produced identifying cause of seal failure with recommendations to improve seal performance.

This is achieved through reliability tracking using John Cranes INTERFACE Reliability Management System which incorporates equipment failure data management, root cause analysis, data consolidation and reporting. The INTERFACE system is a valuable management tool for rotating equipment service and reliability.
