SECTION 6 - TROUBLESHOOTING
WARNING
!
BEFORE DISASSEMBLING THE PUMP, check and consider all
probable causes and follow Pressure Relief Procedure on
page 5.
TEST PROCEDURE
No test is possible. Best economy is to assume o-
ring is faulty.
Visually observe. Start nearest the pump to
ascertain/locate all valves.
Visually observe. Start nearest the pump to
ascertain/locate all valves.
Recommended minimum air pressure regulator 20
psi (1.95 bar), depending on fluid being pumped.
Switch/interchange pilot valves to isolate faulty
pilot valve.
Check for constant exhaust air when pump is not
running.
Constant exhaust noise.
Check for spitting at fluid outlet.
Pump fast cycles on one end of stroke. Indicates
that side is bypassing.
Stall pump on prime stroke to isolate noise.
If noise stops on opposite stroke, only that
seal is faulty.
Pump fast cycles on one end of stroke. Indicates
that side is bypassing.
Check for slow air flow at muffler.
Pump reacts slowly.
Check for sluggish air control valve operation.
Deformed bellows noticed when maintenance
is performed. A damaged bellows may also
leak fluid which will be noticed during normal
operation.
