DECOMMISSIONING EQUIPMENT
When decommissioning equipment it is important to ensure that the pump has been fully isolated from the
process and power sources for personnel safety. Pressure and fluid should be fully released before disassembly
of the equipment is to begin.
•
If the equipment has been used with toxic or hazardous fluids, ensure that it is
decontaminated and neutralized before decommission begins. There is often residual fluid
remaining from the draining process so consult the pump OEM for special cases.
REMOVING THE SEAL
•
Before opening the pump to remove the seal the warning stated above regarding toxins and
hazardous products must be reiterated. Make note of all fluids contained in the pump, drain
and decontaminate before opening the housing for seal service.
1
. Ensure all fluid has been drained and vented. Equipment should be shut down and locked/tagged out
according to OEM and plant specifications.
2
. Dismantle equipment sufficiently so that the gland plate and seal housing are exposed and accessible for
service.
3
. Reset the setting clips that were saved from installation.
4
. Back-out the cup point set screws.
5
. Evenly back-out and remove the cap screws on the drive collar to relieve the compression on the sleeve
packing.
6
. Remove the gland bolts/nuts in an even manner.
7
. Carefully slide the seal out and off of the shaft.
8
. Carefully slide the sleeve packing and drive collar off of the shaft.
If a part is going to be returned for service or to any third party, all shipments should have
appropriate safe-handling instructions securely attached to the package.
