3.For Suction Fed and Gravity Fed models only: With the lubricator operating, count the drops from the drip tube (4) falling into the sight well (2) for one minute.
Calculating Pints per Day

FIG. 10
The number of drops seen falling in the sight well equals the amount of oil discharged by the pump. See Specifi- cations, page 10 for additional information on converting drops to volumetric output.
For Pressure Fed models only: Measure the output volume at the lube point.
4.If any further adjustment is necessary, repeat Steps 2 and 3.
5.Once the pump is adjusted to the proper specifica- tion, tighten the adjusting screw locknut (9) (FIG. 9).
NOTE: Piston stroke length set near zero may cause an inconsistent flow.

*Minimum and Maximum drops per stroke listed in Specifications, page 10.
Example:
The following example calculates the maximum and minimum flow for a 1/4 inch pump model with an electric motor and 300:1 gear ratio.
To calculate the Maximum Flow:
1725 RPM | X | Max 12 drops | X | 1440 min. |
| per stroke | |||
300:1 Gear Ratio |
|
| Max 6.88 | |

= Pints/day
14438(Number of Drops in a Pint)
To calculate the Minimum Flow:
Replace the maximum 12 drops per stroke (used in the equation above) with the minimum 2 drops per stroke = 1.17 minimum pints per day.
