Reassembly Hints & Tips
Upon performing applicable maintenance to the air distribution
system, the pump can now be reassembled. Please refer to
the disassembly instructions for photos and parts placement.
To reassemble the pump, follow the disassembly instructions
in reverse order. The air distribution system needs to be
assembled first, then the diaphragms and finally the wetted
path. Please find the applicable torque specifications on this
page. The following tips will assist in the assembly process.
•
Clean the inside of the center section shaft bushing to ensure no
damage is done to new seals.
•
Stainless bolts should be lubed to reduce the possibility of seizing
during tightening.
•
Be sure to tighten outer pistons simultaneously on PTFE-fitted pumps
to ensure proper torque values.
•
Apply two (2) drops of Loctite
®
246 to the shaft internal threads before
the diaphragm assembly.
