1.6 Check equipment dimensions. They must agree with the
dimensions shown in Figure 1 and the assembly drawing
supplied with the seal. Critical dimensions include shaft or
sleeve OD and the minimum distance to the first obstruction.
1.7 Check gland bolting to ensure that bolt diameter and bolt
circle conform to the dimensions shown in the assembly drawing.
1.8 Check seal chamber stud length to ensure that they conform
to the dimensions shown in the assembly drawing. Assembly may
require longer studs or use of bolts or cap screws if existing studs
are not long enough.
1.9 Check rotation direction of the equipment. Uni-directional seal
designs must be operated only in the direction shown on the
seal gland.
1.10 Handle the seal with care, it is manufactured to precise
tolerances. The sealing faces of the rotors and stators are
specially finished. Keep the seal faces perfectly clean at all
times. Oil, silicone lubrication, or type of grease should not be
applied to these seal faces.
