Abstract
This paper describes how pumps must be matched to operating conditions and power units to provide the desired performance and efficiency. We have recently seen installations where one or more components are not properly matched causing higher than necessary pumping costs. Inspection and maintenance of systems and measurement of flow and pressure will go a long way toward monitoring if the proper conditions are being met. This paper also covers types of pumps, pump components, pump curves, impeller speed and trim, pump staging, affinity laws, pump drives, power units, cavitation, and net positive suction head.
