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).
