Observe and apply the ‘Seal Returns Procedure’. Then proceed with transportation of the seal.
Once the seal is accepted by your local branch it is then shipped to the UK Global Technology Centre.
Inspection begins – Please note in addition to shipping time, please allow for a period of assessment time before a final diagnosis is made.
Your account manager will then contact you to discuss the options available. Such as a warranty repair.
If one of those options is a refurbishment, please read about the Refurbishment process here.

About The ‘Seal Return Procedure’

Prior to sending the product back to our head office, the following procedure must be followed for the Health and Safety of everybody who comes in contact with the seal.

Ensure all information is present and accurate, as this enables the receiver to process the return quickly and efficiently. Failure to complete the process or supply the relevant information, could result in a delay or failure to process the returned seal.

A Simple and Safe System:

Ensure the seal is safe to travel: All seals must be checked by the customer to ensure that they are safe to enter the distribution chain.
All seals that have been in contact with hazardous product must be decontaminated before despatch.
If a seal has not been in contact with hazardous product, the seal does not need to be decontaminated, but the product/fluid it has been in contact with must be stated on bag.
Ensure the Material Safety Data Sheet (MSDS) is supplied in all cases, this is required by the person receiving the seal, it determines what action is required when handling it. As this is unique to your application this documentation should be provided by you and your team. Typically, your health and safety department will have access to this documentation. This is necessary information for the person coming into contact with the seal, to determine what action they need to take when handling it.
Seals should be placed within a ‘Yellow seal return bag’: Please contact your local account manager or nearest branch to acquire a ‘Yellow seal return bag’ and they can arrange for this to be shipped free of charge to your centre. This must be used for hazardous and non-hazardous seals.
All details should be written on the yellow bag and the bag must be sealed prior to shipping. The seal examination request form must also be attached to the yellow bag.
Documentation must not be placed inside the bag!
If the seal is too big to go into a yellow bag, then the bag should be attached to the outer packaging along with the completed form.

Seal Examination Form

If you have any questions regarding the above process, please email sealexaminations@aesseal.co.uk This mailbox is monitored every working day.

The following video summarises the process.

Seal Failure Analysis Reports

These reports are only be issued by Head Office under the full supervision of the UK Technical Applications Manager, or the Group Engineering Director. These reports will detail ‘as found’ states of seals and component parts, and where appropriate (dependant on available information) full Root Cause Analysis (RCA), including conclusions and detailed corrective actions. Actions following reports can allow identification of reoccurring issues e.g. an expensive ‘Mixer Seal’ repaired numerous times in a year with no understanding of why the seal had failed.

The examination report aims to provide the end user with a detailed concise report, discussing the conclusions made from the inspection process and recommendations moving forward. The methodical document includes a systematic de-brief of all the complementary component parts of the mechanical seal, breaking down the report into faces, elastomers, and metallic parts and other necessary supplementary information leading to recommendations moving forward.
