8.0 Calibration

Once installation is complete and the approximate output

has been determined, the pump should be calibrated to adjust

speed and stroke for your actual desired output. (Calibration

cylinders may be purchased from your local LMI distributor,

ref. publication 1798.)

. 1. Be sure the pump is primed, and discharge tubing and Injec-

tion Check Valve are installed as they would be in normal

service (i.e., including factors such as injection pressure,

uid viscosity, and suction lift).

2. Place the Foot Valve in a graduated container with a volume

of 1000 ml or more.

3. Plug in and switch pump to Internal Mode. Pump until all

the air is exhausted from the suction line and head.

4. Turn the pump off. Rell graduated container to a level

starting point.

proceeding.

5. Using a stopwatch or timer, turn the pump on for a measured

amount of time (50 pump strokes minimum). The longer the

time period, the more condent you can be of the results. Be

sure to count the number of strokes during the calibration

period when making comparisons.

6. Turn the pump off. Note the time elapsed in relation to vol-

ume displaced in the graduate. Now, calculate the output in

the time unit you choose (minutes, hours, days, etc.).

7. If the output is too low or too great, adjust speed and or stroke,

estimating required correction and repeat steps 1-7.
