Pump Troubleshooting

DOES NOT OPERATE / GAS APPLIED / DISPENSER VALVE OPEN

• B-I-B empty or inlet tubing pinched off activating vacuum "sold-out".
Gas regulator over-pressurizing.
•
• Outlet tube kinked or restricted.
Operated without fluid for excessive period.
•
Transfer tube and gas lines contaminated
•
out all contaminated pumps]
• Internal damage of control cover.

OPERATES BUT WILL NOT PRIME / DISPENSER VALVE OPEN

[consult Start-up Procedure for proper priming]
• Pump valves have no moisture/dry (add water/syrup to the inlet port with pump stroking slowly).
• Vacuum leaks at Q.D., barb fitting clamps, or inlet fitting o-ring.
• Debris in valve seats or warped/swollen valves.

DOES NOT ACHIEVE SOLD-OUT WITH EMPTY B-I-B

• Vacuum leaks at Q.D., barb fitting clamps, or inlet fitting o-ring.
• Excessive amount of air in B-I-B from improper packaging.
• Air trapped in outlet tubing and/or pump fluid chambers.

AIR IN INLET AND/OR OUTLET TUBING

• Vacuum leaks at Q.D. o-ring or barb fitting clamps.
• Vacuum leaks at inlet fitting; o-ring pinched or missing.
• Large amounts of air noticed only in the outlet tubing when pump operates (diaphragm/piston assem-
blies ruptured).

STROKES WITH DISPENSER VALVE CLOSED

• Air trapped in outlet tubing and/or pump fluid chambers (open outlet and purge air, check for vacuum
leaks, or air in B-I-B).
• Debris in outlet valves or warped/swollen valves.

FLUID FROM EXHAUST OR VISIBLE WITHIN GAS INLET TUBING

• Carbonator check valve.
• Ensure clean gas supply.
• Diaphragm/piston assemblies ruptured.
• [change out all contaminated pumps]

GAS BLOWING FROM EXHAUST CONTINUOUSLY

• Control cover subjected to contaminated gas supply or damaged (ensure clean gas supply, change
out all contaminated pumps).
