Write short notes on Centrifugal pump. Ques10A Centrifugal Pump is a hydraulic machine used to raise the liquids from a lower to a higher level by creating a required pressure by means of centrifugal action. These are the machines which increases the pressure energy of a fluid. These may either lift the fluid or just boost the pressure in a pipe line.Centrifugal Pump Notes, Application, Methods,

How to operate centrifugal fire water pumps

For many process pumps, there have been requirements that head vs. capacity curves should be steep. There have been notes and warnings in different codes and specifications to avoid flat curves for many process or utility pumps. However, the case is totally different for a fire water pump. A relatively flat performance curve (head vs. capacity) is always encouraged for centrifugal fire water

Centrifugal Pump Principle, Parts, Working, Types

A centrifugal pump is the simplest machine which is used in various industries as well as in many daily applications to transfer fluid from lower head to higher head. In 1475, Italian engineer Franc di Giorgio Martini designated mud lifting machine as a centrifugal pump. But actual centrifugal pumps were not discovered until 17th century.

What is priming of a pump amp; Why it is important

Priming a pump is probably the first and one of the most important thing we should have to do before operating the centrifugal pump. It has been found that 8090 % of the pump gets damaged, just not by doing the proper priming of the pump. So first see, in a pump what priming means.
