What is the full load torque ?

The torque applied by a centrifugal pump at full load is called full load torque. It can be calculated from the pump power and its speed.

How to calculate a centrifugal pump full load torque ?

The full load torque of a centrifugal pump can be calculated the following way, it gives the relation in between the pump torque and the pump speed :

T = 30.P / (π.n)

With :
T = Full load torque in kNm
P = Pump power at full load in kW
n = Pump speed at full load in rpm
