How to Read a Pump Performance Curve
A pump performance curve graphically relates flow rate to head, power, efficiency, and NPSH required. Learning to read these curves is essential for selecting…
Head vs Pressure: Why Pumps Are Rated in Feet Instead of PSI
Pump manufacturers express performance in feet of head because head directly represents the energy added to the fluid per unit weight, independent of fluid…
Pump Affinity Laws: How Speed and Impeller Diameter Change Flow, Head, and Power
The pump affinity laws are fundamental scaling relationships that predict how centrifugal pump performance changes when rotational speed or impeller diameter is varied. Flow…
