Troubleshooting
Pump indications
Pump does not cycle.
Pump will not prime.
Pump cycles rapidly.
Pump cycles continuously, or slowly (once or
twice/hour).
External leaks
Product leakage visible at torque hole or bottom
of packing screw (12).
Product leakage visible at top of body (23).
Product leakage visible at bottom of body (23).
Product leakage visible at top of foot valve (40).
Internal leaks
Pump does not prime or cycles continuously, or
slowly (once or twice/hour).
Possible problems
1. Packing screw (12) too tight.
2. Air motor not operating properly.
3. Pump tube jammed and/or contains loose
components.
4. Insufficient air pressure.
1. Excessive cycling speed.
2. Pump leaking internally.
Product source empty.
1. Pump leaking internally.
2. Pump leaking externally.
3. Distribution system leaking.
1. Packing screw (12) not sufficiently tight.
2. Worn or damaged v-packings (19).
3. Damaged piston (11).
1. Gland screw (16) not sufficiently tight.
2. Damaged gasket (22).
1. Pump tube not sufficiently tight.
2. Damaged gasket (22).
1. Foot valve (40) not sufficiently tight.
2. Damaged gasket(s) (22).
1. Foreign material between ball (39) and foot
valve (40).
2. Foreign material between valve (37) and valve
seat (36).
3. Worn or damaged ball (39).
4. Worn or damaged foot valve (40).
5. Worn or damaged valve (37).
6. Worn or damaged valve seat (36).
7. Worn or damaged cup packing (32).

Solution
1. Loosen packing screw (12). Continue to adjust
packing screw until pump begins to cycle at
15 psi (1 bar).
2. Inspect air motor and rebuild or replace as
necessary.
3. Rebuild pump tube.
4. Increase air pressure.
1. Reduce air pressure.
2. → Internal leaks.
Replenish product.
1. → Internal leaks.
2. → External leaks.
3. Correct leak.
1. Tighten packing screw (12) with use of torque
bar.
2. Replace v-packings (19).
3. Inspect piston (11) and replace as necessary.
1. Tighten gland screw (16).
2. Replace gasket (22).
1. Tighten pump tube assembly.
2. Replace gasket (22).
1. Tighten foot valve (40) into cylinder (24).
2. Replace gasket(s) (22).
Locate and eliminate source of foreign material.
Disassemble pump tube, clean, inspect and
replace worn or damaged components.
