The Service Dealer “New Pump Curve” Procedure
This page allows the user to create a pump curve. At the bottom of the screen, there are 3 buttons:
- Reset: Clears the data of the pump curve in progress.
- Auto: Uses needed types of transducers to create the pump curve (Discharge pressure, Suction pressure and
Flow sensor need to be installed.)
- Save: Saves the pump curve and update the pump curve chronological order as displayed in the “History > Pump
Curves” page.
The first line of the legend displays the system units for every column. The second row of the legend describes the
parameters represented and the third line of the legend displays the actual value of these parameters for quick
reference. The scroll bar on the right of the table allows the user to move downward in the table, up to the 10th
point. The new pump curve data will become invalid if the Flow of Pressure units are changed during the input
procedure or if no Flow or Pressure data is entered. In that case, click on the reset button. The Save button must be
used in order to record the pump curve into the ViZiTouch memory.
- Pdis: Discharge Pressure
- Psuc: Suction Pressure
- Pnet: The Net Pressure is calculated by subtracting the Suction Pressure from the Discharge Pressure. In Manual
Mode, it must be entered manually.
- Flow: Flow
- Rpm: Rpm if enable or manually entered.
“Manual Mode”
To manually create a pump curve, data must first be entered on the first row and then on subsequent rows. There
are a total of 10 rows available, but there is no minimum required to get a curve. Of course, more rows improve
precision.
In each column the user must input every following value for maximum information, readability and future reference.
It is possible to create a quick pump curve, but it is not recommended since future references might be less
accurate. In that case, only fill the Pnet and the Flow values. The first row of data must set the “Flow” to 0 and the
last row of data must have a Pnet of 0. These values will ensure the pump curve is fully represented on the graph,
for all pressure and all flows.
When the required number of points are entered, just click on the “Save” button to record the pump curve and exit
this page. You will be redirected to the “History > Pump Curve” page.
