This document specifies methods and procedures for testing, calculating and determining the energy efficiency index (EEI) of booster sets.
A booster set is either a single pump unit or an assembly of pump units connected in parallel with a maximum hydraulic power of 150 kW, a minimum rated flow of 6 m3/h (0,001 667 m3/s), operated with backflow prevention and additional components influencing hydraulic performance and with components necessary to control pressure or provide flow in open loops inside buildings and which is placed on the market and/or put into service as one single product and its intended use is to pump clean water and does not have a self-priming functionality.
A booster set with a rated flow below 6 m3/h is composed using pumps that comply with EN 17038 2.
