„S” dimension can also be set by special Tapflo tool
[T]. Put the tool [T] onto the shaft extension [16] and
fix it with the screw [191], then lean the tool [T]
against internal rim of the back casing [12]. Using an
allen key fix the shaft [16] by tightening screws [161].
NOTE1! Pay attention to the application of the tool
[T]. There are 3 types of tools matching the following
pump sizes:
CT A, CT B
CT C, CT D, CT E
CT C, CT D, CT E with reinforced shaft
NOTE2! The inspection hole allows you to check
whether the face of the shaft [16] touches the tool.
NOTE3! After tightening screw [161] remember to
take off the mounting tool [T].
NOTE4! The set of special tools can be purchased
under Tapflo code 5-355-16MTS

Precisely clean and degrease with alcohol the
internal rim of back casing [12]. Check if the rim
surface is smooth. If not it may be cause of
mechanical seal leakage.
NOTE! For cleaning use dust-free material e.g. blue
towel TORK 1230081.

While unpacking pay attention to the application
(industrial / hygienic) of the mechanical seal [15].
Fig. 3.4.6
Lubricate the static part [15B] of mechanical seal to
provide more accurate assembly as well as prevent
the O-ring from blocking before reaching the surface
of the internal rim.
