Centrifugal pumps Power consumption of the pump pump efficiency Step 3: Find t he power consumpt ion of t he pump at t he point in t he diagram where t he power curve of t he impeller used meet s t he design f low rat e. Select the motor with the next higher power rating. Power consumption according to the diagram: N = 26 kW selected motor: 30.0 kW Step 4: Check t he ef f iciency η = Q H η = × × ρ 367 × N 90 × 75 × 1 367 × 26 Q [m≈/h] H [m] N [kW] ρ [kg/dm≈] ρ water = 1 kg/dm≈
Step 5: Check if NPSH plant > NPSH Pump Resulting NPSH value of the pump from the diagram = 2.4 m Centrifugal pumps Check NPSH value
