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. (Pump stalled)

•Outlet tube kinked or restricted.

•Operated without fluid for excessive period. (Dry run)

•Transfer tube and gas lines contaminated (syrup, rust, oil, etc.) [ensure clean gas supply, change 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).
