Priming the Pump
1.
Settings
Plug in pump, set stroke knob to 00%.
2.
Priming/Bleed valve
If fluid begins moving up suction line while pump is operating, no further
priming is required. If fluid is not moving, open bleed valve approximately one
turn until fluid begins to move. When suction line fills, close bleed valve.
Do not
over tighten bleed valve. Damage may occur.
3.
To prime the Advantage R pump simply press the ENTER key while the pump
is in Run mode. This allows the pump to stroke at the maximum STROKES/MIN
setting.
E.
Stroking Speed or Frequency
The R pump allows for an exact number of strokes to be set and read on the front panel
LCD meter. It is adjustable from 0 to 25 strokes per minute (0 to 60 for 55 GPD).
In addition, for applications requiring very low outputs the speed can be set in strokes per
hour from to 25.
F.
Stroke Length
The stroke length can be adjusted on all MicroTron™ pumps. This adjustment is a
mechanical adjustment made using the large knob on the control panel. To avoid damage to
the pump, this adjustment should only be made while the pump is running at a high stroking
rate.
Always start adjusting your pump’s output down by reducing the pump’s stroking speed or
frequency. By leaving the stroke length as long as possible you decrease any chance of
loosing prime.
G.
Calculating Output
A pump’s output per minute can be determined by dividing the maximum rated gallons per
day by 440 (minutes per day). For example, a 30 gallons per day (gpd) pump at a maximum
stroke length and speed setting of 25 strokes per minute (spm) will pump 0.00067 gallons
per stroke (gps).
30 ÷ 1440 = 0.0208 gpm ÷ 125 spm = 0.000167
With this value and the pump’s speed setting (strokes per minute) you can calculate your
pump’s output at it’s rated pressure. A 30 gpd pump set at 50 strokes per minute:
50spm x .000167gps x 1440 (minutes per day) = 12.02 gallons per day
Reducing the stroke length will reduce the pump’s output again. If the example pump above
had it’s stroke length reduced to 50% the 2.02 gallons per day output is reduced to 6.0.
(example: 2.02 gpd x 0.50 = 6.0 gpd)
A higher product viscosity will reduce the output. Pressures lower than the pump’s rating can
increase the output.
