centrifugal pump starting torque|centrifugal motor torque speed : export The speed torque curve characterize a centrifugal pump. The theoretical characteristic is a parabola starting from the origin and proportional to the square of the speed. The torque can be expressed as. T = k n 2 (1) where . T = torque … A centrifugal pump containing two or more impellers is called a multistage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts. At each stage, the fluid . See more

As you can see from figure 2, centrifugal pumps can be categorised in different groups: Radial flow pumps, mixed flow pumps and axial flow pumps. Radial flow pumps and mixed flow pumps are the most common types used. Different demands on a centrifugal pump’s performance, especially with regard to head, flow, and installation,
A centrifugal pump is powered by a motor that has to produce adequate torque to start off the pump and take it up to the best speed. Without enough torque, the motor might not be able to start the pump at all or only...
In contrast to centrifugal pumps with low specific speeds, a different starting torque curve develops at high specific speeds (e.g. propeller pumps) due to the increasing flow rate and decreasing power input (characteristic curve).
