Troubleshooting

WARNING

Relieve the pressure before checking or servicing 
the equipment.

Check all possible problems and causes before 
disassembling the pump.

To reduce the risk of serious injury whenever you are 
instructed to relieve pressure, always follow the 

Pressure Relief Procedure

 on page 12.

PROBLEM

CAUSE

SOLUTION

Pump cycles at stall or fails to 
hold pressure at stall.

Worn check valve balls (301), seats 
(201) or o-rings (202).

Replace. See page 18.

Pump will not cycle, or cycles 
once and stops.

Air valve is stuck or dirty.

Disassemble and clean air valve. See 
pages 16 to 17. Use filtered air.

Check valve ball (301) severely worn 
and wedged in seat (201) or manifold 
(102 or 103).

Replace ball and seat. See page 18.

Check valve ball (301) is wedged into 
seat (201), due to overpressurization.

Install Pressure Relief Valve (see page 
10).

Dispensing valve clogged.

Relieve pressure and clear valve.

Pump operates erratically.

Clogged suction line.

Inspect; clear.

Sticky or leaking balls (301).

Clean or replace. See page 18.

Diaphragm ruptured.

Replace. See pages 19 to 21.

Restricted exhaust.

Remove restriction.

Air bubbles in fluid.

Suction line is loose.

Tighten.

Diaphragm ruptured.

Replace. See pages 19 to 21.

Loose inlet manifold (102), dam- aged 
seal between manifold and seat (201), 
damaged o-rings (202).

Tighten manifold bolts (106 or 112) or 
replace seats (201) or o-rings (202). 
See page

 18.

Loose fluid side plate (105).

Tighten or replace (pages 19 to 21).

Damaged o-ring (108).

Replace. See pages 19 to 21.
