Description / Abstract:
This Practice describes how to use hydraulic and mechanical
criteria to determine a recommended safe operating flow range for
centrifugal pumps. This Practice does not provide hard limits for a
pump's flow range because of factors that cannot be defined
precisely.
Purpose
This Practice provides recommended minimum and maximum flow
rates for conventional centrifugal pumps (i.e., pumps with
mechanical seals) to achieve safe operation while optimizing
operating costs.
