REVIEW OF EFFECTIVE METHODOLOGIES FOR OPTIMIZATION OF PUMP DISCHARGE CONDITIONS TO ENHANCE OPERATIONAL EFFICIENCY

Almost all industries has a Large use of Cetrifugal Pumps in all capacities .Usually most of the Manufacturing units deploy centrifugal pumps at various operations like Chilled water ,solution transfer ,effluents ,water ,chemicals ,etc .The Pump sizing Generally Designed for Higher Head and Flows considering Peak conditions during the operation. However most of the pump ,due to incorrect assumption fall in low efficiency zone because of Lesser actual Head or Flow requirement .The Review encompasses the three basic methods and their merits and demerits viz 1.Throttling 2.Use of VSD (Variable speed Drive 3.Impeller trimming .The strategy is selected on the basis of the application and load variation and facrots described Here further
