| GLOBAL SERVICE AND SUPPORT – WHEREVER YOU NEED IT |
|
|
As the leading global provider of engineered sealing technology, John Crane creates sealing solutions which increase
operational reliability and reduce the total cost of ownership for the
client.
The company has many notable achievements to its credit, from the creation of the world’s first elastomer bellows seal in 1940,
to the recent introduction of its innovative LaserFace™ sealing
technology. While customers now expect this progressive
approach from John Crane, they also rely on the unparalleled level of service which the company
provides.
Outstanding flexibility, unrivalled technical capabilities and a partnership approach to customers combine to create this
comprehensive service capability. And John Crane’s global network of service centres and support engineers means that
access to it is only ever a phone call away.
No matter what the application or its location, customers know that there is always a local John Crane representative on
hand.
This creates the rapid turnaround times, greater reliability and reduced downtime they expect from the true market leader.

| BRINGING EXISTING EQUIPMENT BACK TO ITS BEST |
|
|
Central to the successful operation of any seal are those
components most vulnerable to wear and tear. Once they begin to wear, the overall efficiency of the seal will
suffer. Peak
performance can often be restored by rebuilding key components rather than replacing
them. This must be done by
qualified and experienced personnel, and this service is exactly what John Crane
provides.
Using the most advanced test and refurbishment facilities, John
Crane rebuilds components and restores seals – whether wet or gas – to their
peak. Customers benefit from longer operating life,
extended periods of peak performance, rapid turnaround times and reduced inventory
costs.
Yet quality is always maintained. John Crane’s own quality approval standards are integrated with customers’ own initiatives
to ensure that the same high level of repair and refurbishment is provided every
time.

| HELPING CUSTOMERS MAKE THE GRADE |
|
|
John Crane’s extensive upgrade and conversion services
reflect its aim of providing a comprehensive sealing solution to every
customer.
The company has the knowledge, skills and resources to upgrade a seal installation in whichever way the customer
wishes. Even the most basic packed gland seal can be
converted to its advanced, mechanical counterpart.
Yet John Crane goes far beyond this, taking great care to understand the intricacies of each individual application
before advising on the most appropriate upgrade or conversion
option.
Advanced technologies, such as ‘tagging’ individual seal
cartridges are used to speed future upgrades and maintenance.
The resulting service provides each customer with increased
reliability, reduced maintenance and far greater mean time
between failure (MTBF), all of which can dramatically reduce the lifetime cost of
ownership.

| INTERFACING SERVICE CAPABILITIES WITH THE LATEST TECHNOLOGY |
|
|
John Crane uses advanced computer technology such as its highly
effective Interface™ reliability management software.
Developed by John Crane’s own specialists, this software approaches service provision with the aim of adding value for the
customer by increasing the ease and efficiency with which they can manage their rotating equipment reliability
programmes.
It incorporates many reporting tools – including both root cause
failure analysis systems and MTBF tracking mechanisms – which provide the necessary data to create accurate pictures of
performance and reliability. This allows improvement programmes to be
created, implemented, and subsequently monitored on a continuous
basis. Other proprietary John Crane
engineering tools assist customers in selecting, designing and implementing the most appropriate sealing
solutions. These tools
undergo constant refinement in order to embrace new material
and tribological developments, and are supported by John Crane’s global application database which provides extensive
background information drawn from experience.

| SETTING A NEW GOLD STANDARD FOR OTHERS TO FOLLOW |
|
|
Nothing demonstrates John Crane’s commitment to customer
support more clearly than Gold Service. Provided free to all seal repair and service
customers, it represents a significant addition to
the company’s service offering.
Typifying John Crane’s partnership approach to customer support,
Gold Service provides a framework for enhanced customer relationships which aims to increase reliability and lower cost of
ownership. John Crane monitors the customer’s repair and servicing
requirements and then uses Root Cause Analysis techniques to identify problem
areas, suspect equipment and operational errors.Remedial action can then be
considered, including specialist
training which John Crane can provide for the customer’s own staff.
An optional feature allows seal components to be standardised, via
a continual upgrade process, simplifying the spares inventory maintenance task. Customers can also utilise a service exchange
system (accessible via e-business channels) whereby whole seals are
replaced – rather than individual components – when due for
servicing, thus cutting spares inventory costs even further.

| RAISING THE STANDARDS |
|
|
In an effort to constantly improve
standards, John Crane
subjects its customer service activities to the same exacting attention as other
activities.
- A rolling international programme for service activities sets demanding benchmarks
- These include quality management systems which measure adherence to ISO 9001
- Continuous improvements in line with updates by the certifying body
- The internationally recognised ISO 14001 standard provides targets against which the environmental impact of John
Crane initiatives can be measured- These initiatives include programmes to reduce water
usage,
carbon dioxide emissions and waste to landfill - Health and safety standards are also constantly
improved, and
this has particular impact on service personnel who work remotely from their own bases
- The internationally-adopted Occupational Health and Safety Assessment Series
(OHSAS) 18001 specification is also being
increasingly adopted along with a new computerised auditing system which benchmarks the health and safety elements of
John Crane sites
