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 connections.
These must be air tight.
Inspect the pump for solid objects lodged in the diaphragm
chamber or the seat area.
