TROUBLE SHOOTING
Product discharged from air exhaust.
Check for diaphragm rupture.
Check tightness of (6) diaphragm nut.
Air Bubbles in product discharge.
Check connections of suction plumbing.
Check “O” rings between intake manifold and fluid caps.
Check tightness of (6) diaphragm nut.
Pump 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.

Pump blows air out main exhaust when stalled on either
stroke.
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 flow if high viscosity fluids are being pumped.
Suction hose must be non-collapsible type, capable of
pulling a high vacuum.
Check all joints on intake manifolds and suction connec-
tions. These must be airtight.
Inspect the pump for solid objects lodged in the dia-
phragm chamber or the seat area.
