Introduction
This document is the fourth part of a series of standards describing a methodology to evaluate energy
efficiency performance of submersible multistage pump units, comprising a rotodynamic pump part and
a submersible motor which is either directly fed from the grid or combined with a frequency converter
(CDM) to form a Power Drive System (PDS). For consistency purposes with other referred standards,
CDM is used in this document. VSD, for variable speed drive, is the term used in Ecodesign regulations.
Rotodynamic pump and motor are designed with outer diameters and special design features that enable
to install them in boreholes and operate them completely surrounded by the pumped liquid. The
methodology is based on a non-dimensional numerical value called Energy Efficiency Index (EEI). An EEI
value allows the comparison of different configurations by one common indicator. Physical influences
such as size and stage number of the incorporated rotodynamic pump, unit part-load operation, motor-
efficiency characteristic and frequency converter influence are implemented into this metric.
Specific requirements for testing and a calculation method for EEI, the so called semi-analytical model
(SAM) of submersible multistage pump units, specific flow-time profiles and reference pressure control
curves are given in this document.
EEI is an index to rate submersible multistage pump units according to their energy efficiency but does
not replace the need to do a life-time cost analysis regarding energy consumption over the lifetime of the
submersible multistage pump unit.
