3.3 O-ring Mounted Stationary Face
3.3.1 Assemble seat gasket to stationary face (lubricate gasket with silicone base
grease only, unless otherwise specified on seal drawing) and install in gland.
Caution: If anti-rotation pin is used, make sure stationary face is properly seated.
Do not get grease on running face.
3.3.2 Install gland gasket - Use silicone grease if necessary to retain gasket.
3.4 Clamped Stationary Face
3.4.1 Install flat gasket into gland.
3.4.2 Install stationary face into gland.
3.4.3 Install second flat gasket to stationary face.
Note: If two gasket materials are supplied, install PTFE gasket at this location.
Use silicone grease to retain gasket if necessary.
Do not get grease on running face.
3.5 Using lint free tissue, clean stationary and rotating face mating surfaces.
Alcohol or acetone can be used as a cleaning agent to assure clean, film free,
dry faces. Any other materials may cause premature seal failure.
Caution: Consult material safety data sheets for proper handling of alcohol or acetone.
3.6 Assemble gland to seal chamber face. See Figure 2.
Caution: During gland assembly over shaft, be sure stationary face is not damaged.
Secure bolts attaching gland to housing.
Note: Even torque is required on all gland bolts to assure proper seal operation.
Tighten gland stud nuts evenly, cross stagger the adjustment of the nuts. Follow the
equipment manufacturer’s recommendation for gland stud nut torque. In the absence
of recommendations, gland stud nuts should only be torqued to establish a leak tight
seal at the gasket. Proper land bolt adjustment is especially important with clamp
style inserts where torque may damage the insert. In this case, gland stud nuts
should be torqued to a maximum of 13.5 N-m (10 ft-lbs).
