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.
•
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 this
page for torque specs).
•
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.
