GB 19762-2007 The minimum allowable values of energy efficiency and evaluating values of energy conservation of centrifugal pump for fresh water (English Version)
This standard specifies the basic requirements, pump efficiency, pump energy efficiency limit value, pump target energy efficiency limit value, and pump energy-saving evaluation value of clean water centrifugal pumps (hereinafter referred to as pumps). This standard applies to single-stage single-suction clean water centrifugal pumps, single-stage double-suction clean water centrifugal pumps, and multi-stage clean water centrifugal pumps. This standard does not apply to other types of pumps.
