Many Common Applications and Classifications of Centrifugal Pump

by Indent Now All You Need, When You Need It.

Centrifugal pumps are one of the most common types of pumps used for the transferring of fluids. In the words of a layman, it can be described as a pump that uses a rotating impeller for the purpose of moving water or some other fluids by using a centrifugal force. These pumps would be a perfect choice for delivering liquid from one location to the other in multiple industries, including pharmaceuticals, power generation plants, municipal, petroleum and agriculture. People can easily check out Kirloskar Pumps Catalogue, or centrifugal pumps of other brands, online to find the ideal Centrifugal Pumps for their use. 

Centrifugal pumps are specially designed for liquids with relatively low viscosity and tend to pour like a light oil or water. Superiorly viscous liquids such as 10 or 20 wt. oils at 68-70 deg F will need a bit of additional horsepower for the centrifugal pumps to work. However, in case the viscous liquids are more than 30 wt. oils, positive displacement pumps should be used to transfer them instead of centrifugal pumps, so as to facilitate energy costs.

Applications of Centrifugal Pumps

Centrifugal Pumps are used extensively across multiple industries. They are effective in pumping water for domestic requirements, boosting pressure, water circulation, sewage drainage, assisting fire protection systems and supplying water. Here are some of the major sectors where centrifugal pumps are most commonly used:

  • Oil and Energy: It is used by power generation plants and refineries for the purpose of pumping slurry, crude oil, and mud.
  • Industrial and fire protection Industry: These pumps are used for boiler feed applications, pressure boosting, fire protection sprinkler systems, as well as heating and ventilation.
  • Waste Management, Agriculture and Manufacturing: The centrifugal pumps are common in municipal industry and wastewater processing plants, and is used for drainage, irrigation, and flood protection
  • Pharmaceutical, Chemical, and Food Industries: In the production process of beverages, petrochemical, cellulose, paints and hydrocarbons centrifugal pumps are commonly used.

Centrifugal pumps are additionally used purposes of cryogenics and refrigerants in multiple industries, such as aerospace, food production, manufacturing, pharmaceutical, and chemicals.

Types of centrifugal pumps

Depending on factors like service, application, design, and construction, centrifugal pumps can be classified into multiple types.  They can be classified in regard to compliance with a national or industry-standard as well. 

Depending on the number of impellers in the pump, centrifugal pumps can be categorized into the following:

  • Single Stage: Featuring one impeller pump, the single stage pumps are known for their easy maintenance features and easy design. They are perfect for low-pressure installations and large flow rates. They are quite commonly used in pumping services of high flow and low to moderate TDH or Total Dynamic Head.
  • Two-Stage: Popularly used for medium head applications, such pumps have two impellers operating side by side.
  • Multi-Stage: These pumps are meant for high head service and have three or more impellers in series.

Through the Kirloskar Pumps Catalogue or brochures of other pump brands, people can get detailed information about diverse types of centrifugal pumps available in the market and specifications, and subsequently purchase the products that they like the best.
