GB 19762-2025 Minimum allowable values of energy efficiency and energy efficiency grades for centrifugal pumps
Abstract
This document specifies the energy efficiency grades, energy efficiency limits, energy efficiency calculation methods, and testing methods for centrifugal pumps (including clean water centrifugal pumps and petrochemical centrifugal pumps).
This document is applicable to:
a) single-stage single-suction clean water centrifugal pumps, single-stage double-suction clean water centrifugal pumps, pipeline clean water centrifugal pumps, multi-stage clean water centrifugal pumps, and lightweight multi-stage clean water centrifugal pumps;
b) single-stage single-suction petrochemical centrifugal pumps, single-stage double-suction petrochemical centrifugal pumps, and multi-stage petrochemical centrifugal pumps used for transporting clean liquids and equipped with closed impellers.
This document is not applicable to non-metallic centrifugal pumps and rotary power pumps without shaft seals.
