REASSEMBLY HINTS & TIPS
ASSEMBLY:
Upon performing applicable maintenance to the air distri-
bution system, the pump can now be reassembled. Please
refer to the disassembly instructions for photos and parts
placement. To reassemble the pump, follow the disassem-
bly 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.
