Pump Solutions Group Neptune Series 560 dia-PUMP - Manual (Page 18)

* Silicone Sealant may be substituted for Gasket “N” indicates parts per new version
Valve stacks of all Series 560 (except PVC models) have been improved by the attention of close tolerance ball guides which
allow for better accuracy and higher pressure performance.
Improved stack arrangements are shown in the figures on page #15.
Parts are currently furnished only for the improved version. When ordering replacement seats for an original valve stack
design, order the ball guides (FIG. #5691) and spacer (FIG. #5693). Installing these parts and discarding the old spacers (FIG.
#2320 and FIG. #2326) will upgrade the pump to the Improved valve arrangement. (Refer to the drawing on page#15)
If seats are not replaced, it is not necessary to change the spacers and ball guides. If seats are replaced (the new seals are of a
different thickness) the ball guides and spacers must be replaced.
