These seals are provided in two sub-assemblies:

The stationary unit will face up.
2. Install the rotary unit and take care not to disengage the rotary parts.
Installation becomes difficult when the rotary unit parts become disengaged.
IMPORTANT: Do not tighten the setscrews or adjust the seal until the impellers are adjusted.
3. Adjust the seal:
a) Refer to the spring gap which is stamped on the collar and shown on the seal assembly drawing.
b) Tighten the setscrews so that the compression ring is maintained at the same distance from the
collar at all points.
c) Before you start the pump, make sure that the spring gap and the distance from the face of the
stuffing box to the collar are the same as shown on the seal assembly drawing.
