Scope

This Standard specifies the basic requirements for petrochemical centrifugal
pumps (hereinafter referred to as “pumps”), efficiency calculation methods for
pumps, energy efficiency grades for pumps, minimum allowable values of
energy efficiency for pumps, target minimum allowable values of energy
efficiency for pumps, and evaluating values of energy conservation for pumps.
This Standard applies to single-stage single-suction pumps and single-stage
double-suction pumps with closed (maximum) impellers installed which deliver
clean liquids.
This Standard does not apply to clean-water centrifugal pumps, non-metallic
centrifugal pumps, and seal-less rotodynamic pumps.
