Introduction 2. Centrifugal Pump Problems 3. Alfa Laval Solutions to Specific Centrifugal Pump Problems 4.

Centrifugal pumps should never be allowed to operate in the wrong direction of rotation. If the pump is not fitted with an impeller screw the impeller may unscrew from the shaft making contact with the casing, thereby causing seizure. To ensure correct direction of rotation the motor can be started and stopped momentarily to check the

gal pumps: radial flow, mixed flow and axial flow based on the direction the fluid enters the inlet (eye) of the impeller, see figure 1.2. Radial and mixed flow pumps are either single or double suction designs. A centrifugal pump produces head, H as a function of the rate of fluid flow, Q through the impeller, see figure 1.3. Head
