How does the efficiency of a pump affect WHP calculations?WHP provides a theoretical value. A pump's efficiency determines how much actual power (BHP) needs to be provided to achieve the calculated WHP. Lower efficiency requires more BHP for the same WHP.Infant...

The Efficiency-Flowrate Curve at Centrifugal Pump Performance TestThe efficiency-flowrate (ƞ-Q) curve can be plotted based on measured values from combination of H-q curve and P-q curve and this formula ƞ=(P out of Pump)/(P input of Pump)=ρgHQ/(P input of pump) (ρ is ...
High pump efficiency – Europe’s largest wastewater treatment project The 51 km long Emscher sewer is considered to be the largest wastewater project in Europe and serves the sustainable restoration of the River Emscher in the Ruhr area of Germany. Today, 21 specially designed KSB pumps in two...
Machines with an adjustable resistance have a high efficiency. Checking the tower This is another important tip that should always be considered when purchasing a good machine. Rowers are made using high-quality materials to provide the much-needed grip. Apart from this, its slide track length ...
Also called a pump selection curve, pump characteristic curve, efficiency curve, or pump performance curve, a pump curve chart gives you the information you need to determine a pump's ability to produce flow under the conditions that affect pump performance. Reading pump characteristic curves more...
