Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: trap a fixed amount of fluid and then force it into a discharge pipe.

• Axial flow pumps: move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial flow
