TROUBLE SHOOTING
Product discharged from air exhaust.
S
Check for diaphragm rupture.
S
Check tightness of (6) diaphragm nut.
Air Bubbles in Product Discharge.
S
Check connections of suction plumbing.
S
Check band clamps on intake manifold.
S
Check O" rings between intake manifold and fluid caps.
S
Check tightness of diaphragm nut.
Pump blows air out main exhaust when stalled on either stroke.
S
Check U" cups on (111) spool in major valve.
S

Low output volume.
S
Check air supply.
S
Check for plugged outlet hose.
S
For the pump to prime itself, it must be mounted in the vertical posiĆ
tion so that the balls will check by gravity.
S
Check for pump cavitation - suction pipe should be 1/2" min. or
larger if high viscosity fluids are being pumped. Suction hose must
be nonĆcollapsible type, capable of pulling a high vacuum.
S
Check all joints on intake manifolds and suction connections.
These must be airtight.
S
Check for sticking or improperly seating check valves.
S
If pump cycles at a high rate or runs erratically, check (119) piston
O" rings for wear.
