A catalogue is where selection starts and the common language of international inquiry.

Read the performance curve

Horizontal axis is flow Q (m³/h), vertical is head H (m). The duty point should sit near the best-efficiency zone.

Check NPSH and power

The NPSHr curve sets the installation height; the power table sets the motor and running cost.

Engineer's tip
State flow/head/medium/temperature/pipe size in your inquiry for an accurate quote.
