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 “O” rings between intake manifold and fluid caps.
S Check tightness of (6) diaphragm nut.
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 (169) “U” cup on (167) pilot piston.
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 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-col-
lapsible type, capable of pulling a high vacuum.
S Check all jointson intake manifolds andsuctionconnections. These
must be airtight.
S Inspect thepumpfor solid objectslodgedin the diaphragm chamber
or the seat area.
