GB 19762-2005 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 energy efficiency limit value, energy saving evaluation value and test method of clean water centrifugal pump (hereinafter referred to as pump). This standard applies to single-stage clean water centrifugal pumps (single-suction and double-suction), multi-stage clean water centrifugal pumps, long-shaft centrifugal deep well pumps and centrifugal pumps with media similar to clean water. This standard does not apply to other types of pumps.
