3.2.3 Start-Up/Priming for AUTOPRIME™
Heads (LE-XXXAX or LE-XXXHX)
READ THIS ENTIRE SECTION
COMPLETELY BEFORE PRO-
CEEDING.
When all precautionary steps have been taken,
the pump is mounted, and the tubing is securely
attached, you may prime the pump.
1. Plug in or switch on the pump.
2. While the pump is running, set the speed knob
and the stroke knob at 100%.
3. The suction tubing should begin to fill with
solution from the tank as the AUTOPRIME™
valve purges air from the pump head.
4. Once the solution begins to exit the pump
head through both the discharge valve and
the AUTOPRIME™ valve,
SHUT THE PUMP
OFF
.
5. The pump is now primed.
6. Proceed to output adjustment, Section 3.3.
3.3 OUTPUT ADJUSTMENT
Once the pump has been primed, an appropriate
output adjustment MUST be made. Pump output
should be calculated and adjustments made
accordingly.
3.3.1 Total Pump Output
Calculate the approximate output of the pump as
follows:
PUMP OUTPUT :
MAX PUMP OUTPUT X % SPEED X % STROKE
Example: AD251-938SI
Use Max Output (from dataplate on side of pump)
= 1 GPH (1 gallon per hour).
If the pump is set at 60 strokes per minute
(out of a possible 120 SPM) and 70% stroke length,
the approximate pump output is:
1.0 x 60/120 x 0.70 = 0.35 GPH.
Multiply by 24 (hours in one day) to calculate in
gallons per day.
Note:
When converting between different units,
remember these conversion factors:
1 Gallon = 3.785 Liters
1 Day = 1,440 Minutes
120 SPM = 7,200 SPH
IT IS IMPORTANT TO NOTE THAT
THIS IS ONLY AN APPROXIMATE
OUTPUT AND IT DOES NOT ACCOUNT FOR TOLERANCE
VARIATIONS IN PUMP COMPONENTS OR FLOW VARIATIONS
DUE TO PRESSURE SENSITIVITY, OR VISCOSITY EFFECTS.
VARIATIONS DUE TO THESE EFFECTS CAN BE SIGNIFICANT,
NECESSITATING CALIBRATION FOR YOUR PUMP.
