1 Equipment Check
1.1 Follow plant safety regulations prior to equipment disassembly:
• lock out motor and valves.
• wear designated personal safety equipment.
• relieve any pressure in system.
• consult plant MSDS files for hazardous material regulations.
1.2 Disassemble equipment to allow access to seal installation area.
1.3 Remove all burrs and sharp edges from the shaft or sleeve
including sharp edges of keyways and threads. Replace worn shaft
or sleeve. Make sure the seal housing bore and face are clean and
free of burrs.
1.4 Check requirements for shaft, sleeve and seal housing.
See Figure 1.
1.5 Check assembly drawing included with the seal for specific seal
design, materials of construction, dimensions, and piping
connections.
1.6 Check shaft or sleeve OD, box bore, box depth, and distance
to the first obstruction to ensure that they are dimensionally the
same as shown on the seal assembly drawing.
1.7 Check gland pilot and bolt holes to ensure they are adaptable to
the equipment and are the same as shown on the assembly drawing.
