Pump #1 Calibration - USC LP2000 Operator's Manual

The following steps illustrate how to calibrate pump #1 on an LP series seed treater.
A stop watch will be needed in the calibration process.
If the seed treater is equipped with a flow meter, refer to the Flow
Meter operator's manual for pump calibration instructions.
1. Lock down the pump tubing in the Pump #1 pump head (page 23) and set the
dial above the pump head to the "3" setting.
2. Premix enough liquid for the amount of seed you will be treating and pour into
the 27 gallon stainless steel tank. It's always a good practice to mix up 20% ex-
tra slurry to help fill all the lines. Turn on the mix tank and allow liquid to mix.
3. Turn the "SEED TREATMENT SOURCE" valve to the "MIX TANK" position, the
"SEED TREATMENT" valve to the "CALIBRATE" position, and the valve on top
of the mix tank to "MIX TANK".
4. Turn the pump #1 direction switch to "FORWARD".
5. Turn the "Hand/Off/Auto" switch to the "Hand" position and set
the Pump #1 liquid adjust dial (right) to about "500" or half
speed. The liquid should begin re-circulating from the bottom of
the mix tank, through the pump, and back into the top of the mix
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 re-circulate you are ready to calibrate the
pump. Determine the number of ounces needed in one minute.
EXAMPLE: The seed treatment slurry rate is 4 ounces per cwt.
Seed Flow Rate = 12.24 cwt/min. x 4 oz./cwt. = 49 oz./min.
49 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 42 to find a
starting point.
EXAMPLE: The ounces needed in one minute = 49 oz/min. Assume we are
using a 2-200 Masterflex pump. An approximate starting point is 31.8
volts.
