TROUBLE SHOOTING
Product discharged from exhaust outlet.
Check for diaphragm rupture.
Check tightness of (14) bolt.
Air bubbles in product discharge.
Check connections of suction plumbing.
Check “O” rings between intake manifold and uid caps.
Check tightness of (14) bolt.
Motor blows air out main exhaust when stalled on
either stroke.
Check “U” cups on (111) spool in major valve.
Check (141) valve plate and (140) insert for wear.
Check (169) “U” cup on (167) pilot piston.

Low output volume.
Check air supply.
Check for plugged outlet hose.
For the pump to prime itself, it must be mounted in the
vertical position so that the balls will check by gravity.
Check for pump cavitation - suction pipe should be sized
at least as large as the inlet thread diameter of the pump
for proper ow if high viscosity uids are being pumped.
Suction hose must be a non-collapsing type, capable of
pulling a high volume.
Check all joints on the inlet manifolds and suction con-
nections. These must be air tight.
Inspect the pump for solid objects lodged in the dia-
phragm chamber or the seat area.
