Duty point

Duty point 18-3

This is the point where the pump curve and the system curve intersect. If nothing changes, the centrifugal pump will pump at this point. Hopefully this will be within 10% of the pump’s best efficiency point. (BEP).

If the pump curve does not intersect the system curve at or near the BEP, you can:

  • Adjust the pump speed by using a variable frequency drive  (VFD)
  • Adjust the system curve by throttling the system curve.
