Pressure loss Pump Curve  


System curve and pump curve
Pump Curve 5





Define your pump curve in 5 steps
  1. Upload your pump curve as .txt file if you saved it in the past from TECCINESS.
  2. Enter title and medium. Choose between turbo-machine (centrifugal pump) and positive displacement pump.
  3. Enter flow, head and power (optional) for at least two points of the pump curve. For positive displacement pumps often 2 points are sufficient since the pump curve can be nicely approached by a straight line.
  4. If the pump is run with a variable frequency drive up to 3 frequencies can be evaluated. Pumps an series and in parallel can be simulated.
  5. Save your data.
