Centrifugal pumps are one of the most popular and commonly used pumps in India. They are used for several applications ranging from domestic to industrial. The versatility and flexibility of these pumps make them the number one choice for displacing fluids in a variety of industries like agriculture, wastewater plants, municipal water treatment plans, power generation plants, pharmaceutical, chemical, mining, petroleum and several others.
Centrifugal pumps work on the action of a centrifugal force. At Sintech, the best pump dealer in India, we offer a wide range of centrifugal pumps for various industrial applications. In this article, we highlight the principle, working and major applications of centrifugal pumps in India.
Working Principle of a Centrifugal Pump
Centrifugal pumps are used to displace (raise) a liquid from low levels to high levels. The working mechanism of centrifugal pumps are quite simple but highly efficient. It converts rotational energy to kinetic energy, with the help of a motor. The energy conversion occurs due to two main parts of the pump:
The impeller &
The rotating part of the centrifugal pump is known as the impeller and the static part that surrounds the impeller is the casing.
How do centrifugal pumps work?
The displaced liquid enters the casing and falls on the blades of the impeller. This causes the impeller to rotate creating a centrifugal force that displaces the fluid outward. The process repeats until the fluid leaves the impeller and reaches the diffuser end of the casing. The fluid gains both velocity and pressure as it passes via the impeller to the casing. This causes the fluid to flow from a low-level area to a high-level area, creating the desired motion.
Major Industrial Uses of Centrifugal Pumps in India
The versatility of centrifugal pumps and simple operation make them the perfect choice for a wide range of industrial applications like:
Agriculture and irrigation
Petroleum and chemicals
Food processing & beverages
Boiler feed applications
Pharmaceutical and more
Centrifugal pumps are used in industries where little or no suction lift is required. Besides industrial applications, centrifugal pumps are also used for numerous domestic applications. They are the primary pumps used for pumping municipal water in residential buildings.
Additionally, the design of centrifugal pumps makes them suitable for applications involving slurries and sewage. Since centrifugal pumps can handle liquids with high viscosity, they are also used in food and beverage applications, milk processing and dairy industries, etc.
Some Popular Applications of Centrifugal Pumps in India include:
Chemical Processing Industries
Centrifugal pumps are used in chemical processing industries like paints manufacturing, cellulose making, petrochemicals, etc.
Centrifugal pumps are used in the mining industry as froth pumps to separate bitumen and other minerals from sand and clay.
As Booster Pumps
Centrifugal pumps help in boosting pressure by taking the pressure from the main channel and transfer it further ahead. When switched on, these booster pumps can run automatically during set periods.
As Daily water pumps
Centrifugal pumps are used to transfer water in day-to-day applications that do not require much suction lift. They are mostly used in pneumatic and overhead water systems. For centrifugal pumps to function efficiently, they need to have a suction line with an attached valve. It can provide suction lifts up to 15 feet.
As Fire-protection Systems
Centrifugal pumps are used for hot water circulation in closed systems. Their flexibility and low head, make them a great fit here.
For Sump Drainage
Centrifugal pumps are used in sewage applications to drain the slurry and sewage. The pump can be mounted either vertically or horizontally, depending on the application.
The versatility, uncomplicated design, few moving parts and low maintenance – make centrifugal pumps the primary choice for industrial applications.
