Get Price### Pump Head Calculation Pump Performance Calculation

The head and flow rate determine the performance of a pump, which is graphically shown in the figure as the performance curve or pump characteristic curve. The main reason for using head instead of pressure to determine the performance of a centrifugal pump is that the height of the fluid column is not dependent on the specific gravity (weight) of the liquid,while the pressure from a pump

A centrifugal pump converts input power to kinetic energy by accelerating liquid in a revolving device an impeller. The most common is the volute pump where fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid accelerates radially outward from the pump chasing and a vacuum is created at the impellers eye that continuously draws more fluid into the
