Check equipment dimensions to ensure that they are within the
dimensions shown in Figures 1 and 2.
Critical dimensions include:
• Box Bore (ØC)
• Box Depth (G)
• Distance to First Obstruction (K)
• Pump Frame accomodates Gland OD (ØE)
5.6 Check gland bolting to ensure that bolt diameter and bolt circle
conform to the dimensions shown in Figure 2.

!
Handle the ISC with care, it is manufactured to precise toler-
ances.
The sealing faces of the ISC seal are the Primary Ring and the
Mating Ring.
They are lapped flat to within three light bands (0.9 µm).
Keep the seal faces perfectly clean at all times.
!
If the pump condition exceeds the above criteria ( including con-
sideration for thermal growth), consult Flowserve Application
Engineering for recommendations to avoid seal performance com-
promises.
Seal Chamber Requirements
The MS may be installed when there are no visible signs of
damage to the MS. This applies in particular to the seats,
centrings, and the statically sealing O-rings.
