CENTRIFUGAL PUMP
Centrifugal pumps are the most commonly used pump on plants and platforms. They have a low
initial cost compared to other types of pump and are easily maintained due to their simple
construction and small number of moving parts. All centrifugal pumps need to have a flooded
suction which means that liquid must fill the suction of the pump for it to operate properly.
Centrifugal pumps use centrifugal force to move fluids. Liquid flows into the pump by the inlet or
suction port into the center (the eye) of the impeller. As the liquid moves from the eye to the rim
it causes a low-pressure area in the eye which draws more liquid into the pump.
The rotation of the impeller increases the kinetic energy of fluid.
When the liquid flows through diffuser of volute, the kinetic energy of the liquid converts into
pressure energy. The liquid is discharged from the casing through the discharge port of the pump.
