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 pumpвЂ™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.
