Shut off Pressure / Design Pressure Ratio
- Thread starter shahyar
- Start date
Steepness of centrifugal pump head-flow curves generally depends on pump specific speed with axial flow pumps of high specific speeds having the steepest curves and the highest shutoff to design flow head ratios which might approach or even exceed 2.0. See Stepanoff's plots for various head-flow versus specific speed characteristics.
