Assembly
1. Clamp the shaft flats in a vise.
2. Assemble the air side plate onto the diaphragm. The
rounded side of the plate must face the diaphragm.
3. Apply medium-strength (blue) Loctite or equivalent
to the threads of the diaphragm assembly. Screw
the assembly into the shaft as tight as possible by
hand.
4. Apply lithium-based grease to the shaft u-cups (in
center housing) and the length and ends of the dia-
phragm shaft. Slide the shaft into the housing.
5. Reattach the first fluid cover. Follow Torque
Instructions in the manual.
6. Repeat Steps 2 and 3 for the other diaphragm
assembly.
7. To ensure proper seating and extend diaphragm life,
attach the second fluid cover with air pressure on
the pump.
a. Place the supplied tool (104) where the air valve
gasket normally goes. Arrows (A) must face
toward the fluid cover that is already attached.
b. Reattach the air valve.
c. Supply a minimum of 20 psi (0.14 MPa,
1.4 bar) air pressure to the air valve. Shop air
may be used. The diaphragm will shift so the
second fluid cover will seat properly. Keep air
pressure on until the second fluid cover is
attached.
d. Attach the second fluid cover. Follow Torque
Instructions in the manual.
e. Remove the air valve and the tool (104), replace
the gasket, and reattach the air valve. Follow
Torque Instructions in the manual.
NOTE: If you are replacing the diaphragms but not the
air valve, you must remove the air valve and gasket, put
the tool in place of the gasket, and put the air valve back
on to get the air pressure needed for proper installation
of the second fluid cover. Remember to remove the tool
and replace the gasket when finished.
8. Reassemble the ball check valves and manifolds as
explained in the manual.
