Understanding Centrifugal Pump and Motor TorqueSpeed Curves

Oct 08, 20190183;32;A pumps torquespeed curve is produced by plotting the percentage of full load torque (FLT) vertically against the percentage of full load speed (FLS) plotted horizontally. An example is shown below. The torquespeed curve is similar for all centrifugal pumps due to simple math the pump torque varies as the square of its speed.

Understanding Centrifugal Pump and Motor TorqueSpeed Curves

Oct 08, 20190183;32;If a motor lacks enough torque to operate a pump, the pump may not start or may only operate at a reduced speed.
