On December 29, 2022, the Standardization Administration of China (SAC) released a batch of mandatory national standards on energy efficiency, as below:

The main revised contents on pumps are summarized as below:

GB 32030-2022 Minimum allowable values of energy efficiency and energy efficiency grades for submersible motor-pumps

This standard applies to the small, medium, and large size submersible motor-pumps, waste submersible motor-pumps, submersible motor for deep well and mined flow submersible motor-pump. Comparing with the existing three standards, the main modifications include:

·   Changed the efficiency grade value and minimum allowable value for small-size, waste and deep well pumps, and add those for medium and large size, as well as mined flow pumps.

·   Modified the basic requirement for submersible motor-pumps.

·   Changed some definitions and terms.

·   Cancelled the chapters related to energy-saving assessment value, testing rules and energy efficiency marking.

There was no indication of any international standards being cited by the GB 32030-2022. This standard is China national specific standard without any connection of IEC standard.

Foreign manufacturers are advised to verify whether the applying scope change would affect current products, as well as if any possible impacts would be caused by the revised requirements.

As the standard is different from IEC standards, the overseas manufacturers should read these standards carefully to check if your products comply with them.
