UNDERSTANDING & IEC STANDARDS WASTEWATER PUMP MOTOR EFFICIENCIES

摘要

Today pumps account for no less than 10% of the world's consumption of electricity, and two-thirds of all pumps use up to 60% too much electricity. As a consequence, reducing energy costs through the development of more energy efficient electric motors has become a priority for end-users, environmental legislators, governments and manufacturers. Over the past decade a substantial effort has been put into harmonising the different test and classification standards around the globe, and the subsequent labelling schemes in use. The International Electrotechnical Commission (IEC) has worked together with NEMA, CEMEP, IEEE and other international organizations and this work resulted in the publication of two major standards.
