Replacing Variseal
NOTE: When the pump shaft seal needs to be replaced, Nordson
recommends replacing the pump and sending the old one in to be repaired.
Only trained personnel using special assembly tools can replace the pump
shaft seal.
NOTE: Nordson cannot provide a guarantee for Variseals that have been
replaced by anyone besides a Nordson employee.
1. Remove the gear pump from the melter but do not disassemble it!
Refer to Replacing Gear Pump in this section.
2. Have a new seal and a suitable assembly tool ready.
Assembly Tool
Fig. 7‐21
The assembly tool is used to slide new seals over the shaft journal and the
pump shaft pulley key groove without damaging the seals.
CAUTION: The seal must be put into place using the tool; otherwise the seal
will be destroyed.
1. Follow the instructions Assembly Tools for Sealing Kits with Variseal
Seals (P/N 7146229) to proceed.
2. Put the gear pump back into place.
