REASSEMBLY HINTS & TIPS
REASSEMBLY
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.
•
Ensure proper alignment on the sealing surfaces of
intake and discharge manifolds.
•
Liquid chambers are easier to attach when the
diaphragm is inverted. Prior to attaching the second
water chamber, push diaphragm assembly so that it is
as close as possible to the center section.
•
PVDF and PFA pumps require PTFE gasket kits for
improved sealing. Gasket kits may be installed on
other pumps where sealing is an issue.
•
When assembling PTFE-coated hardware, care should
be taken to keep the coating intact.
•
When installing Glyd™ rings, the use of the Wilden
Ringer tool simplifies seal installation
