Series 1250 Pneumatic Chemical Injection Pump
Operating Manual
To ensure accurate stroke rate measurement, allow sufficient measurement duration. Count all
exhaust discharges for at least thirty (30) seconds, then convert to a stroke per minute rate. When
attempting to control the pump at a frequency lower than 2 strokes per minute, time at least three
strokes, then divide by the number of minutes to calculate the stroke per minute rate.

Finally, ensure that the Target Stroke Rate does not exceed the maximum recommended stroke rate. If the
Target Stroke Rate exceeds the maximum recommended stroke rate for the type of service you intend, it will be
necessary to use a larger plunger size:

Assuming your pump is correctly sized, simply adjust the speed control valve on your pump until the Target
Stroke Rate is achieved.
