Why do the inlet and outlet pipe diameters of a centrifugal pump need to be reduced?

Reply #22017-11-05

Since the pressure of the medium at the inlet is lower than that at the outlet, the outlet head is much higher than the inlet pressure. The larger diameter of the inlet pipe results in less suction resistance, which facilitates the pump’s absorption of the medium, while the smaller diameter of the outlet pipe helps to maintain the pressure at the pump’s outlet.
