SECTION 3 - OPERATION
3.2.2 Start-Up / Priming for Pump Supplied
with 4-FV
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 now start priming the pump.
1. Plug in or switch the pump ON.
2. While the pump is running, set the Speed
Adjustment Knob and the Stroke Adjustment
Knob at 100%.
3. Open the relief side (black knob) of the 4-FV by
turning to the stop (about 1/8 turn).
4. The suction tubing should begin to fill with
solution from the tank.
5. A small amount of solution will begin to
discharge out the return line of the 4-FV. Once
this happens, return the knob to the 12:00
position and
SHUT THE PUMP OFF
.
6. The pump is now primed.
7. Proceed to output adjustment,
Section 3.3
.
NOTE:
If the pump does not self-prime, remove the
4-FV on the discharge side of the pump head.
Remove the check valve and pour water or
solution into the port until the head is filled.
Replace valve, then follow start up / priming
steps.
3.2.3 Start-Up / Priming Without 4-FV
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.
4. Once the solution begins to exit the
pump head on the discharge side,
SHUT THE PUMP OFF
.
5. The pump is now primed.
6. Proceed to output adjustment,
Section 3.3
.
NOTE:
If the pump does not self-prime, remove the
discharge check valve and pour water or
solution into the port until the head is filled.
Replace valve, then follow start up / priming
steps.
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: A151-928SI
Use Max Output (from data plate on side of pump)
= 1 GPH (1 gallon per hour).
If the pump is set at 60% speed and 70% stroke
length, the approximate pump output is:
1.0 x 0.60 x 0.70 = 0.42 GPH.
Multiply by 24 (hours in one day) to calculate in
gallons per day. If pump is not equipped with speed
adjustment, calculate by
Max Pump Output x
% Stroke only
.
NOTE:
When converting between different units,
remember these conversion factors:
1 Gallon = 3.785 Liters
1 Day = 1,440 Minutes
240 SPM = 14,400 SPH
