(6) To reinstall the diaphragm, first fit a new diaphragm in the diaphragm base groove while aligning
the two diaphragm projections with their counterparts of the diaphragm base. Then, replace the
diaphragm ring in the diaphragm thus fitted. At this time, this diaphragm ring must be a new one
supplied with the replacement diaphragm. (Figs. 11 and 12.)
This completes the diaphragm replacement procedure, and use this assembly as a new
diaphragm mounting block.
• At the time of changing diaphragms, be sure to replace the diaphragm rings also with the supplied
new ones. Since the old diaphragm rings may be likely to break, you may get injured when attemp-
tingto refit them for reuse.
• Be sure to fit the diaphragm ring as pump performance and life will be greatly affected, possibly
resulting in a failure.

(7) Install a new diaphragm mounting block on one side of the rod, insert the rod in accordance with
the procedure reverse to that performed when the rod was removed from the pump.
• Do not use removed U-lock nut and washer again as they may be loosened, which causes failure
of the pump. Therefore, use new U-lock nut and washer every time for replacing diaphragms
without fail.
