2 Disassembly

When disassembling seal, inspect for conditions which may have caused the

need for the seal to be removed from service. If seal was removed due to

premature failure, determine what conditions caused that failure and correct any

problems prior to returning the repaired seal to service. For assistance with seal

failure analysis, please contact your Flowserve representative.

These instructions are written for trained, experienced technicians familiar with the basic

principles and tools involved in the installation, care and service of mechanical seals and seal

support systems. A complete reading of these instructions by personnel in contact with the

equipment is essential to safety. Incorrect installation, operation or maintenance can result in

personal injury or death to personnel and damage to the equipment.
