5.1 Follow plant safety regulations prior to equipment disassembly:
• lock out motor and valves.
• wear designated personal safety equipment.
• relieve any pressure in the system.
• consult plant MSDS files for hazardous material regulations.
5.2 Disassemble pump in accordance with equipment manufac-
turer's instructions and remove sealing arrangement.
5.3 Check seal documentation for seal design and materials of
construction. Verify that the ISC2 seal is designed for the
equipment being repaired.
5. Check seal assembly drawing for any modifications required
to the equipment before installation and act accordingly.
5.5 Check shaft or pump sleeve OD, seal chamber depth, seal
chamber bore, distance to the fi rst obstruction, gland pilot
and gland bolting to ensure they are dimensionally within the
tolerances shown on the seal assembly drawing.
5.6 Thoroughly inspect and clean the seal chamber and shaft or
pump sleeve. Inspect for corrosion or any defects. Remove
all burrs, cuts, dents or defects that might damage gaskets
or allow a leak path. Replace worn shaft or pump sleeve.
Remove sharp edges from keyways and threads.

reading greater than what is allowed must be brought within
