Flowserve SLC Series Interseal - Manual (Page 8)

5.1 Apply a light coating of O-ring lubricant to the index finger and thumb and pull
seal sleeve and flange/gland O-ring element through fingers to inspect for nicks
or cuts. Install O-rings in their proper groove locations. This process will help
prevent an excessive amount of lubricant from being applied to the O-ring ele-
ments (non-petroleum based grease must be used with EPDM materials).
Caution: Do not apply anti-seize or other lubrication to the equipment shaft or
shaft sleeve. Keep shaft or shaft sleeves clean and dry. The use of lubricants
will cause improper clamping pressure by the seal split clamp/drive collar.
5.2 With the seal split clamp/drive collar pointing toward the bearing assembly,
slide the complete cartridge over the equipment shaft or shaft sleeve. Push seal
flange/gland back toward bearing housing. See Figure 10.
Important: Do not hammer or push against rotary face housing or seal sleeve.

5.3 Bolt seal adapter plate to equipment casing/pedestal (hand tighten only).
5.4 Locate the seal fit of the adapter to the shaft by use of a dial indicator or center-
ing jig. The equipment shaft must be concentric to the seal adapter bore to
within 0.25 mm (0.010 inch) FIM (TIR). See Figure 11. Seal life can vary with
improper alignment; poor shaft alignment will yield poor seal life.
