6. Clean or replace any components that have excessive wear, dirt build-up, or chemical attack. Lube all compo-
nents prior to reassembling. Reassemble pilot sleeve spacers (45), o-rings (4) and lip seals (4) within bore
of intermediate. Make sure that the open side of the lip seals (4) is facing outward toward the diaphragms.
Also make sure that the end pilot spacers (45) are at the end on either side of the pilot sleeve assembly and all
inner spacers (48) are separated by o-rings (5). Next carefully insert the diaphragm rod assembly (34,49) with
pilot sleeve (3) inside the assembly in the bore. Reattach retaining plates (46). Do not overtighten self-tapping
screws (38).
7. With the curved side of the inner diaphragm plate (33) facing the diaphragm, assemble onto outer diaphragm
plate stud (9) and then screw assembly into diaphragm rod. Push diaphragm rod to opposite side of intermedi-
ate and add the opposite diaphragm assembly. Apply 4 Nm of torque to outer diaphragm plates (9). Assemble
the outer chamber (8) and band clamps (6) first on the side where the diaphragm has been inverted. Next
reach under the opposite diaphragm assembly and pull diaphragm rod to opposite side (a large flat screw driver
may be used as an aid in this process) and assemble remaining outer chamber and band clamp. When position-
ing outer diaphragm chambers onto intermediate make sure that witness lines are matching.
Caution!
If air valve has been removed, proper orientation of air system with fluid chambers must be observed. The
top of the intermediate has a single vertical air passage slot on the air valve mounting face while the outer
chamber chack ball cavity should be pointing downward.
Caution!
When positioning band clamps use soapy water or a compatible lubricating spray on the inside of band
clamps to aid assembly. Tap with a mallet on the outside of clamp to help position the clamp while tightening
the fasteners.To prevent galling always apply an anti-seize compound to the thread.
Tighten all external fasteners to final torque requirement after pump is completely assembled.
8. Position the reassembled manifolds making sure of the proper orientation in relation to the air valve for your
application. Also make sure that the valve seat o-rings do not shift from their grooves during reassembly. Flat
washers should be placed under the head of each cap screw and nut. Tighten all external fasteners to final
torque requirement after pump is completely assembled.
8a. Metallic pumps: Position manifold/elbow sections making sure that the valve seat o-rings do not shift from their
grooves. Tighten fasteners on bolts loosely.
3.8.3 External fastener torque requirements
Caution!
When reassembling, loosely tighten all external fasteners adjusting and aligning and gradually, in an alternat-
ing fashion, tighten to torque requirements listed below.
Band clamps (outer chamber – all versions) 8 Nm
Band clamps (manifolds and elbow) 9 Nm
Metallic pumps (elbow and chamber bolts) 50 Nm
