TROUBLE SHOOTING
Productdischarged from exhaust outlet.
SCheckfor diaphragm rupture.
SChecktightness of bolt (14).
Airbubbles in product discharge.
SCheckconnections of suction plumbing.
SCheck“O” rings between intake manifold and fluid caps.
SChecktightness of bolt (14).
Pumpblows air out main exhaust when stalled on either stroke, a
typicalcause of pump malfunction can be attributed to problems
with“O” rings.
SSegmentsof broken “O” rings can move around or lodge in areas of
theair motor valve section.
SSwollen“O” rings can cause valve parts to stick or seize. Solvents
canruin the “O” rings.
SDonot use contaminated air supply.
SDonot use light weight oil in air supply,it will wash the Key-Lube
greaseout of the air motor section.
SDonot use air line additives containing solvents.
SDonot spray pump off with solvents, wipe clean only.
SCheck“O” rings on (111) spool in major valve.
SCheck(103) sleeve and (2) “O” ring on (1) rod.
SCheck(168) “O” rings on (167) pilot piston for wear.
Lowoutput volume.
SCheckair supply.
SCheckfor plugged outlet hose.
SForthe pump to prime itself, it must be mounted in the vertical posi-
tionso that the balls will check by gravity.
SCheckfor pump cavitation -- suction pipe should be 1” minimum or
largerif high viscosity fluids are being pumped. Suction hose must
benon-collapsible type, capable of pulling a high vacuum.
SCheckall joints on intake manifolds and suction connections. These
mustbe airtight.
SCheckfor sticking or improperly seating check valves.
SIfpump cycles at a high rate or runs erratically,check (168) “O” rings
forwear.
