Pump Calibration - Graco ProMix 2KE Operation

Pump Calibration

Calibrate the pump:
• The first time the system is operated.
• Whenever new materials are used in the system,
especially if the materials have viscosities that differ
significantly.
• At least once per month as part of regular mainte-
nance.
• Whenever a pump is serviced or replaced.
NOTE:
• Pump factors on Calibration 1 (Screen 22) are
updated automatically after the calibration pro-
cedure is completed. You also may manually
edit them if desired.
• All values on this screen are in cc or cc/in., inde-
pendent of the units set in Configure 4 (Screen
21).
1. Before calibrating pump A or B, prime the system
with material. See Prime the System, page 26.
2. On the Display Module, press
screens.
3. Press to display Calibrate 1 (Screen 22).
K-factors are shown for Pump A and Pump B.
4. Press to move to Calibration 2 (Screen 23).
5. Press to highlight the pump you wish to cali-
brate. An X displays in the box. Press
6. Press to start the calibration on the highlighted
pump (A or B). Press
7. Trigger gun into a graduated cylinder. Dispense
about 200-300cc of material.

NOTE: Stop triggering the gun when desired amount is
reached. Do not press
tion.
8. The volume that the ProMix measured displays on
the Display Module.

9. Compare the amount on the Display Module to the
amount in the graduated cylinder.
NOTE: For maximum accuracy, use a gravimetric
(mass) method to determine the actual volumes dis-
pensed.
10. If the screen and actual volumes are different, enter
the actual dispensed volume in cc for the A or B
field, and press
If the value was substantially different, repeat the
calibration process.
11. After the volume for A or B is entered, the ProMix
2KE controller calculates the new pump factor and
shows it on Calibration 1 (Screen 22) and Calibra-
tion 2 (Screen 23).
12. Before you begin production, clear the system of
solvent and prime it with material.
a. Go to Mix mode.
b. Trigger the gun into a grounded metal pail until
mixed material flows from the gun nozzle.
c. To begin operation, see Spraying, page 27.
