Follow plant safety regulations prior to equipment disassembly.
Disassemble equipment in accordance with manufacturer instructions for seal area access.
Remove old seal and thoroughly clean seal chamber and shaft.
Inspect surfaces for pits/scratches and break sharp corners on shaft steps and threads.
Check shaft, bore, and bolt pattern dimensions against seal assembly drawing.
Check seal assembly drawings for any required equipment modifications.
Ensure equipment is earthed to prevent sparks from static electricity discharge.
Verify shaft runout against specifications, typically 0.05 mm (0.002 inch) TIR.
Limit shaft endplay to 0.25 mm (0.010 inch) TIR, regardless of bearing type.
Check radial bearing play against manufacturer specifications (0.05-0.10 mm typical).
Ensure seal chamber squareness to shaft centerline is within 0.0005 mm/mm.
Check shaft to seal chamber bore concentricity, max 0.125 mm (0.005 inch) TIR.
Specifies required surface finish (Ra) for seal housing, bore, and shaft.
Lightly lubricate the shaft with silicone lubricant before installing the seal assembly.
Install the complete cartridge seal assembly over the shaft, taking care with O-rings.
Tighten gland bolts to the seal chamber evenly, cross staggering the adjustment.
Tighten sleeve collar set screws to the shaft, ensuring proper hardness and staggering.
Remove and store the setting devices from between the sleeve drive collar and gland.
Do not start the equipment dry; always properly vent the pump of air.
If seal runs hot, check setting, housing dimensions, and flush lines for obstructions.
Always start sealing liquid supply before equipment, ensuring pressure exceeds process fluid.
Seal liquid pressure must not exceed the pressure velocity rating of the seal design.
Ensure cooling water to the supply tank or circulator is on.
Never start equipment dry; properly vent all air.
If seal runs hot, check seal liquid flow and housing dimensions for over-compression.
Use only Flowserve parts for repair; order parts using part code and B/M number.
