Centrifugal pumps consist of a set of rotating
vanes, enclosed within a housing or casing, that are used to impart energy
to a fluid through centrifugal force.
About Centrifugal Pumps
Centrifugal pumps consist of a set of rotating vanes,
enclosed within a housing or casing, used to impart energy to a fluid
through centrifugal force. The pump has two main parts: a rotating element
which includes an impeller and a shaft, and a stationary element made up
of a casing (volute or solid), stuffing box, and bearings. Centrifugal
pumps operate using kinetic energy to move fluid utilizing an impeller and
a circular pump casing. The impeller produces liquid velocity and the
casing forces the liquid to discharge from the pump converting velocity to
pressure. This is accomplished by offsetting the impeller in the casing,
and by maintaining a close clearance between the impeller and the casing
at the cutwater. The fluid enters the pump near the center of the impeller
and is moved to its outside diameter by the rotating motion of the
impeller. The vanes on the impeller progressively widen from the center of
the impeller that reduces speed and increases pressure. This allows
centrifugal pumps to produce continuous flows at high pressure. By forcing
the fluid through without cupping it, centrifugal pumps can achieve a very
high flow rate.
Centrifugal pumps are used in many industries. Some of
their most common applications /media transferred include: general purpose
fluids, pure water, sludge and sewage, slurry, high viscosity fluids,
power generation, the paper industry, the petroleum industry, chemicals
and corrosives, gravel and solid materials, high temperature materials,
and marine applications.
Centrifugal pumps generate flow by using one of three
actions: radial flow, mixed flow, and axial flow. These classifications do
not rate the performance quality of the pump, they are merely groupings
based upon the pump’s action.
Radial flow pumps are centrifugal pumps in which the
pressure is developed wholly by centrifugal force. In mixed flow pumps,
the pressure is developed partly by centrifugal force and partly by the
lift of the vanes of the impeller on the liquid. Axial flow centrifugal
pumps develop pressure by the propelling or lifting action of the vanes of
the impeller on the liquid.
