Installation of a PSS II and III on a Goulds 3410 Pump can be simplified
by following the supplemental instructions below. These instructions
should be used in conjunction with the standard PSS II and III Installation
Instructions.
1. After making the appropriate checks and prior to installing the seal,
remove the slingers on the 3410 S and L models (reference Table 1).
If a labyrinth is used on the bearing frame, the seal will not fit. Check
