Pumps are those devices
which move fluids with the help of mechanical action. Pumps have been
made highly advanced over the years with the help of latest
technology skills. There are various kinds of pumps used worldwide.
However, the most common type used in water distribution applications are the Centrifugal Pumps. A Centrifugal Pump is employed broadly
in the modern process plants which are known for giving a smooth and
continuous flow of liquids with simple operation. It has the ability
to operate under a large diversity of conditions.
A vast variety of pumps have
been developed over the years, which are used largely in several
major applications for rendering distinct services. Some of them are-
- Drainage Pump- Used to remove accumulated water in a water-collecting sump basin, or basements of homes.
- Flood Control Pump- Specializes in preventing the occurrence of pumps and protecting the areas by pumping away large volumes of water.
- Propeller Pump- Driven by a motor, this device is used to flow water through a linear path, along with the impeller situated below the water level.
- Fire Fighting Pump- They are efficiently used in the absence of local municipal water system to provide the needed pressure in order to meet the hydraulic requirements of the fire sprinkler system.
Centrifugal Pumps also known
as Roto-Dynamic Pumps comprises of axial, radial, and mixed flow
units, and can be classified further as-
- Submersible Pumps
- End Suction Pumps
- In-Line Pumps
- Axial-Flow Pumps
- Horizontal Multistage Pumps
- Vertical Multisatge Pumps
- Self-Priming Pumps
- Double-Suction Pumps
- Regenerative Pumps
Centrifugal Pumps are
the most inexpensive pumps, employed in municipal, agricultural,
petroleum, and power generation industries. This device consists of a
number of components such as Impeller, Casing, Shaft, Shaft Sealing,
Bearings, etc., which are designed to perform specific tasks. The
pump when operated creates an increase in the fluid pressure from the
pump inlet to its outlet, the difference in pressure then moves the
fluid through the system. So now, we know why Centrifugal Pump is
chosen over any other pump.
