How To Find The Stroke Setting
NOTE: Read this procedure, then study the example be-
fore determining the stroke setting.
1. Set the adjuster to 480 on the indicator (12). Operate
the pump to measure the Maximum Full Stroke
Output of the displacement pump, measure the out-
put in
ounces.
2. Multiply the Maximum Full Stroke Output by 0.375
(37 1/2% – a constant number) which gives the Mini-
mum Output Possible.
3. The Output Range is all of the numbers between the
Minimum Output Possible and Maximum Full Stroke
Output.
4. Determine the Lowest Number in the Output Range
which can be evenly divided into the Container Size,
and then divide that number into the total ounces of
the container to get the Ounces Per Cycle.
5. Subtract the Minimum Output Possible from the
needed Ounces Per Cycle to determine the Vari-
able Number.
6. Subtract the Minimum Output Possible from the
Maximum Full Stroke Output to determine the
Output Range Number.
7. Divide the Variable Number by the Output Range
Number to determine the Percent of Range.
8. Multiply the Percent of Range by 4.83 (a constant
number) to determine the Trial Setting.
EXAMPLE:
1.
In this example, the Maximum Full Stroke Output
is 8 oz. The Container Size is 20 oz.

(YOUR TRIAL SETTING)
NOTE: Remember, the pump exhausts twice each
cycle, so in this case, set the counter to 8 (2 x 4)
rather than 4 which is the lowest number in the
output range which divides evenly into the con-
tainer size.
