TROUBLE SHOOTING
Product discharged from air exhaust.
S Check for diaphragm rupture.
S Check tightness of (14) bolt.
Air Bubbles in product discharge.
S Check connections of suction plumbing.
S Check “O” rings between intake manifold and fluid caps.
S Check tightness of (14) bolt.
Pump blows air out main exhaust when stalled on either stroke.
S Check “U” cups on (111) spool in major valve.
S Check (141) valve plate and (140) insert for wear.
S Check (103) sleeve and (2) “O” ring on diaphragm connecting rod.
S Check (119) “O” rings on (118) piston for wear.
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 posi-
tion so that the balls will check by gravity.
S Check for pump cavitation -suction pipe should be1/2” minimum or
larger if high viscosity fluids are being pumped. Suction hose must
be non-collapsible type, capable of pulling a high vacuum.
S Checkall jointson intakemanifolds andsuction 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.
