BS EN 16480:2021

This standard BS EN 16480:2021 Pumps. Rotodynamic pumps. Minimum required efficiency of water pumps and determination of Minimum Efficiency Index (MEI) is classified in these ICS categories:

• 23.080 Pumps

This document specifies performance requirements (methods and procedures for testing and calculating) for determining the Minimum Efficiency Index (MEI) of rotodynamic glanded water pumps for pumping clean water, including where integrated in other products.

The pump types and sizes covered by this document are described in the Annex A. These pumps are designed and produced as duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, for all pumps designed for fluid temperatures between ?10 °C and +120 °C. Also covered are 4” (10,16 cm) and 6” (15,24 cm) submersible multistage pumps designed for fluid temperatures between 0 °C and 90 °C.
