Reassembly Hints & Tips
Upon performing applicable maintenance to the air
distribution system, the pump can now be reassembled.
Please refer to the disassembly instructions beginning on
page 14 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 (beginning on page 16), then
the diaphragms and finally the wetted path. The applicable
torque specifications are 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.
•
Level the water chamber side of the
intake/discharge manifold to ensure a
proper sealing surface. This is most easily
accomplished by placing them on a flat
• surface prior to tightening their clamp
bands to the desired torque (see below
for Torque Specifications).
• Be sure to tighten outer pistons simultaneously on PTFE-fitted
pumps
to ensure proper torque values.
•
Ensure proper mating of liquid chambers to manifolds
prior to tightening vertical bolts. Overhang should be
equal on both sides.
• Apply a small amount of Loctite 242 to the shaft interval
threads before the diaphragm assembly.
•
Concave side of disc spring in diaphragm assembly
faces toward shaft.
