  With maximum efficiency a centrifugal pump generally work. Centrifugal pump perform in various way when the pump is run at different condition at different conditions from it’s design conditions. The pump under various conditions to symbol of   the behavior such as speed, tests, powers, discharges, heads are usually conducted. If we plot this result of a characteristics of a pump in graph paper we find a curve which is called characteristics curve. About the performance of a pump in it’s installation these curve provide important information. For centrifugal pump one can make various types of characteristics curve such  as 1.       Constant discharge curve 2.         Constant head curves 3.       Main characteristics curve 4.       Constants efficiency curves 5.       Operating characteristics curve 6.       Muschel curves                              Merits of Centrifygal Pump   Classification of Centrifugal Pump    

  For high heads and small discharges the reciprocating pumps are still employed of higher efficiency. High pressure can be build up by a reciprocating pump. It also be used for lifting oil from very deep oil wells. 1.       Output from the pump is uniform 2.       On the power source the torque is uniform 3.       Centrifugal pump cost is lower then it parts 4.       Capability of discharge is greater than of a reciprocating pump 5.       It can be employed for lighting highly viscous liquid such as paper pulp, muddy and sewage water, oil, sugar and molasses etc. 6.       Maintenance and installation is cheaper and easier. 7.       It is hands and compact is smaller size and weight for same capacity for the energy transfer. 8.       An oil engine or an electric motor it can be coupled directly. 9.       Characteristics are superior of it’s performance 10.   Without any danger cavitation and separation it can be operated very high speed.  

Centrifugal Pump    A centrifugal pump is a contrivance which provides energy to a fluid in a fluid system. It assist to increase the pressure energy or kinetic energy or both of the fluid by converting the mechanical energy.   What is basic difference   between   a Turbine and The Pump?   The basic difference between a turbine and   the pump, from hydrodynamic point of views. Is that in the former flow takes place from the high pressure side to low pressure side. Whereas in pump flow take place from the low pressure towards the high pressure. Thus in a   turbine there is accelerated flow,   while the pump the flow is decelerated.   Why transformer is rated in KVA?                                                                             How and Why an increase in secondary or load current causes an increase in primary current?                                                What is the difference between dynamo breaking a
