3.9 Wipe the seal faces clean with alcohol. Seal faces should not be
lubricated but be left clean and dry.
3.10 Position the rotating assembly so that the seal faces are in
contact and position the spring holder so that the spring gap (or
bellows rotary unit length) is that shown on the assembly drawing.
Tighten the set screws firmly and evenly.
3.11 See paragraph 4, Operational Recommendations before starting
pump.
Note: Seal designs incorporating a bushing style stationary face do
not include a gland. Lubricate the stuffing box bore and the O-rings with
the silicone lubricant provided with the seal. Hand press the bushing into
the bore of the stuffing box. Follow the above procedures for installation
of the rotating seal components.
4 Operational Recommendations
4.1 Do not start up the equipment dry. Vent air from the casing of
the pump and the stuffing box before start-up. Circulate clean
product or a clean fluid from an external source through the stuffing
box whenever the equipment is in operation, Plan 11 or 32.
4.2 If the seal runs hot, check for proper seal setting, seal housing
dimensions, and check the bypass or flush line for obstructions.
Do not allow the equipment to run for any extended time if the
seal gets hot or squeals.
For special problems encountered during installation, contact your
nearest Flowserve Sales and Service Representative or Authorized
Distributor.
