Centrifugal Pump is widely used in Pumping of Water Application

The operation of
a Centrifugal Pump can be explained by using the flow velocity triangle. It
shows how a centrifugal pump works by transforming dynamic mechanical energy
from a motor into kinetic energy within pumped liquids. Some of this energy is
converted into potential energy as fluid pressure against gravity. During a
pump operation cycle, liquids enter the pump through the suction flange and
travel through the rotating impellers, increasing their velocity as they pass
by.
The design of
the pump plays a vital role in determining its efficiency. A multistage pump
may require a sump pit or barrel that costs a lot of money to construct. A
multistage pump can lead to mechanical seal problems and entrained gas
accumulating on the top of the stuffing box or seal chamber. Therefore, it's
crucial to choose a pump with good-quality components for high efficiency and
long-term durability. Centrifugal
Pump are produced by a variety of manufacturers, each offering a
different range of designs and capabilities. The head of a centrifugal pump is
a combination of the weight and pressure of the fluid it is pumping. The Head
is the height the pump can lift liquid. The impeller design of different pumps
varies as well. A single-suction pump, for example, only allows liquid to enter
through one side of the impeller and has a higher axial thrust imbalance. A double-suction
pump, on the other hand, has a lower net positive suction head.
In addition to
pumping water, these pumps can also be used for the transfer of solvents, oils,
and thin liquids. However, they do not work well with high-viscosity liquids
and require a lot of horsepowers. Positive displacement pumps, on the other
hand, operate at lower speeds, which helps to reduce the pump's energy
requirements. And finally, positive displacement pumps are more
energy-efficient than these pumps.
