LPH800 TREATER
The following steps illustrate how to calibrate pump #2 on an LP series seed treater.
A stop watch and measuring cup will be needed in the calibration process.
1. Lock down the pump tubing in the Pump #2 pump head. (page 22)
2. Premix enough liquid for the amount of seed you are treating and pour into the
5 gallon poly tank. It’s always a good practice to mix up 20% extra slurry to help
fill all the lines.
3. Turn the INOCULANT valve to the CALIBRATE position, and the Calibration Valve
to RECIRCULATE.
4. Turn the pump #2 direction switch to FORWARD.
5. Turn the HAND / OFF / AUTO switch to the Hand position and set
the Pump #2 liquid adjustment dial (right) to about 500 or half
speed. Liquid should begin circulating from the bottom of the mix
tank, through the pump, and back into the top of the tank.
6. Allow pump to re
-
circulate liquid for approximately 15 minutes to
ensure all air has been removed from the liquid lines. This will also
help break
-
in the pump tubing, which is critical before checking
pump calibration.
7. After you have allowed the liquid to circulate you are ready to calibrate the liquid
flow. Determine the number of ounces needed in one minute.
EXAMPLE: The seed treatment slurry rate is 5 ounces per cwt.
Seed Flow Rate = 6.41 cwt/min. x 5 oz./cwt. = 32.1 oz./min.
32.1 oz. is the rate the pump should be pumping in one minute.
8. Set the Liquid Adjustment Dial . You can use the chart on page 34 to find a starting
point.
EXAMPLE: The ounces needed in one minute = 32.1 oz/min. Assume we are
using a 6
-
600 Masterflex pump. A good starting point is approximately
39.4 volts.
9. Using the stop watch and measuring cup, determine the pump flow rate. Hold the
measuring cup under the calibration hose next to the Side Valve.
10. Keeping the pump running, position the Calibration Valve to CALIBRATE.
When liquid begin timing for one minute as soon as liquid begins flowing into the
measuring cup.
