Installing the Seal
(continued)
It is recommended that the seal cavity be vented through the pump’s lantern
ring connection located at top dead center. It is always recommended that a
flush injection be utilized. The flush should be piped into the seal gland to
ensure maximum efficiency.
For DIN pumps rotate gland 135˚ CCW. Use port #2 as flush.
NOTE:
For CCW (counter clockwise) rotation pumps,
consult John Crane engineering.

Decommissioning the Equipment
1.
Ensure that the equipment is electrically isolated.
If the equipment has been used on toxic or hazardous
fluids, ensure that the equipment is correctly decontami-
nated and made safe prior to commencing work.
Remember, fluid is often trapped during draining and
may exist outside the seal. The equipment instruction
manual should be consulted to check for any special pre-
cautions.
2.
Ensure that the equipment is isolated by the appropriate valves.
Check that the fluid is drained and pressure is fully released.
Maintenance
No maintenance of a seal is possible while installed. Therefore, it is
recommended that a spare seal unit be held in stock to allow immediate
replacement of a removed seal.
It is recommended that used seals are returned to a John Crane service
location, as rebuilding to as-new specifications must be carried out by
qualified personnel.
It is the responsibility of the equipment user to ensure that any
parts being sent to a third party have appropriate safe
handling instructions externally attached to the package.
Quality Assurance
This seal has been assembled in accordance with John Crane quality
assurance standards and with proper maintenance and use will give safe
and reliable operation to the maximum recommended performance as
shown in any relevant approved John Crane publication.
