Operating range charts

The graphs shown bellow, indicate the range of operation for DELTA axial and mixed flow pumps from 500 to 1250 mm in diameter. The three digit figures shown on the graphs represent the model diameter (050 means a 500 mm diameter pump).

For pumps sizes different from those shown on the graphs, or for complete performance curves showing capacity, head, rpm, efficiency, and NPSHR, please contact us.
