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.
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) (F
IG. 9).
NOTE: Piston stroke length set near zero may cause an
inconsistent flow.
Calculating Output Capacity
The number of drops observed falling in the sight well
equals the amount of oil discharged by the pump. The
pump volume can be adjusted using the adjusting screw
(8) (F
IG. 9) to change the piston stroke. (See Adjusting
the Pump.)
Calculating Pints per Day
Calculating Minimum or Maximum Pump Output
Capacity in Pints per Day
* 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:
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.
