Understand The Basics Of Centrifugal Pump Operation
Centrifugal pumps operate within ranges of head and ve-locity. Operating outside of these ranges may require using a of about 10% for a small centrifugal pump, to a high of 80% for a large cooling-water type pump. Another item to consider is pump failure. ... View Document
