Energy Labelling of Glanded Pumps (Dry-Motor) Pump

摘要

Objective Small circulators are labelled according to the Europump aggreement from 2005. This paper present two new methods for labelling pumps (larger pumps) according to energy consumption. The new methods make it now possible to lable a large number of pumps-all of the kind single stage centrifugal. The labelling scheme implemented in the Danish market is expected to reduce the electricity consumption by 200GWh or almost 10 percent of all electricity consumed by pumps. Content The paper describes two different methods for labeling pumps: (1) This method is used for larger circulators in heating system. In principle it is the same method as
