Troubleshooting

Problem

Cause

Solution

Pump does not run.

There is no fluid demand.

In a closed-end system, the pump 
runs only when there is demand for 
fluid.

Air supply is insufficient.

Check air supply. Increase air 
pressure or volume.

Fluid outlet line or intake valve is 
clogged.

Relieve the pressure, 

page 7

.

 

Check and clear obstacles.

Air motor parts are worn or 
damaged.

Check the piston o-rings (15a*, 
15b*) and exhaust plate (15c*) for 
swelling. Replace if necessary. See 
Service instructions beginning on 
page 9.

Check the piston assembly (15). Be 
sure its screws are properly torqued 
(10 to 14 in-lb [1.3 to 1.6 N•m]) and 
that the assembly is hand-tightened 
onto the piston rod.

Check the springs (8, 17) for wear or 
damage and replace as needed.

Pump speeds up or runs erratically.

Material viscosity is too high.

Reduce viscosity. Reduce pump 
speed when running viscous 
materials.

Pump throat packings, piston or 
piston packings, or intake valve is 
worn.

Relieve the pressure,

 page 7. 

Check and repair. See Service 
instructions beginning on page 9.

Pump slows down or runs erratically.

Air motor is icing.

Shut off pump and allow to warm up. 
Run pump at a lower air pressure.

Pump runs, but output is low on up 
or down stroke.

Pump piston and/or intake valve is 
worn.

Relieve the pressure,

 page 7. 

Check and repair. See Service 
instructions beginning on page 9.

Pump runs, but output is low on both 
strokes.

Air supply is insufficient.

Check air supply. Increase air 
pressure or volume.

Fluid outlet line, intake valve, or 
dispense valve is clogged.

Relieve the pressure,

 page 7. 

Check and repair.
