TROUBLE SHOOTING
Product discharged from exhaust outlet.
S
Check for diaphragm rupture.
S
Check tightness of bolt (14).
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 bolt (14).
Pump blows air out main exhaust when stalled on either stroke, a
typical cause of pump malfunction can be attributed to problems
with “O” rings.
S
Segments of broken “O” rings can move around or lodge in areas of
the air motor valve section.
S
Swollen “O” rings can cause valve parts to stick or seize. Solvents
can ruin the “O” rings.
S
Do not use contaminated air supply.
S
Do not use light weight oil in air supply, it will wash the Key-Lube
grease out of the air motor section.
S
Do not use air line additives containing solvents.
S
Do not spray pump off with solvents, wipe clean only.
S
Check “O” rings on (111) spool in major valve.
S
Check (103) sleeve and (2) “O” ring on (1) rod.
S
Check (168) “O” rings on (167) pilot 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 be 1” minimum or
larger if high viscosity fluids are being pumped. Suction hose must
be non-collapsible 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 (168) “O” rings
for wear.
