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 bore
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.
• Concave side of disc spring in diaphragm assembly faces
toward inner piston.
