Nowadays, centrifugal pumps are often controlled by adjusting their rotational speed, which affects the resulting flow rate and output pressure of the pumped fluid and the changing rotation speed is the most effective and economical way of improving the pump efficiency. In this paper it is proved that the variable frequency drive induced in the stepper motor of the centrifugal pump do affect the discharge of the centrifugal pump. The motor speed here is varied between 2200-3100 rpm and the change in value of discharge is plotted in a graph. The value of discharge increases with increase in speed in motor of centrifugal pump.
