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.

Liquid pumps and pumps units - Noise test code - Grades 2 and 3 of accuracy (ISO 20361:2019)
SIST EN ISO 20361:2019

This document specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.
Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for
—          declaring the noise emission values, and
—          purpose of noise control at source at the design stage.
The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market.
The use of this document ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to this document are engineering methods (grade 2) and survey methods (grade 3).
This document does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.
NOTE       This document is specified in EN 809+A1 for noise measurements of the pump (or pump unit).

Pumps - Methods of qualification and verification of the Energy Efficiency Index for rotodynamic pump units - Part 1: General requirements and procedures for testing and calculation of Energy Efficiency Index (EEI)
SIST EN 17038-1:2019

This document describes a methodology to evaluate energy efficiency performance of pump units based on a non-dimensional numerical value called Energy Efficiency Index (EEI).
This document covers pump units consisting of:
-   one single or several rotodynamic water pump(s), including where integrated in other products, and driven by a motor system, consisting of an electrical motor, and either:
-   a terminal box which only enables to operate the pump unit at constant motor stator frequency and thereby (nearly) constant rotational speed, or
-   a CDM (Complete Drive Module) which enables to operate the pump unit at variable rotational speed depending on a varying demand of flow rate and/or discharge or differential pressure.
NOTE   A CDM is also often called VSD (Variable Speed Drive).
Pump units as defined above are treated as extended products in respect to their energy efficiency.

Pump system energy assessment (ISO/ASME 14414:2019)
SIST EN ISO 14414:2019

This document sets the requirements for conducting and reporting the results of a pumping system energy assessment (hereafter referenced as "assessment") that considers the entire pumping system, from energy inputs to the work performed as the result of these inputs.
The objective of a pumping system energy assessment is to determine the current energy consumption of an existing system and identify ways to improve system efficiency.
These requirements consist of
—          organizing and conducting an assessment,
—          analysing the data from the assessment, and
—          reporting and documenting assessment findings.
This document is designed to be applied, to open and closed loop pumping systems typically used at industrial, institutional, commercial, and municipal facilities, when requested.
This document is focused on assessing electrically-driven pumping systems, which are dominant in most facilities, but is also applicable with other types of drivers, such as steam turbines and engines. The document does not
a)    specify how to design a pumping system,
b)    give detailed qualifications and expertise required of the person using the International Standard although provides a list of body of knowledge in Annex C,
c)    address the training or certification of persons,
d)    specify how to implement the recommendations developed during the assessment, but does include requirements for an action plan,
e)    specify how to measure and validate the energy savings that result from implementing assessment recommendations,
f)     specify how to make measurements and how to calibrate test equipment used during the assessment,
g)    specify how to estimate the implementation cost or conduct financial analysis for recommendations developed during the assessment,
h)    specify specific steps required for safe operation of equipment during the assessment. The facility personnel in charge of normal operation of the equipment are responsible for ensuring that it is operated safely during the data collection phase of the assessment,
i)     address issues of intellectual property, security, confidentiality, and safety.

Centrifugal pumps - Test procedure for seal packings
SIST EN 16752:2015

This European Standard gives details of a test procedure for packings to be used to seal the stuffing boxes of centrifugal pumps. It gives provisions on the design of test equipment, standard test parameters and reporting criteria. It does not specify performance criteria which should be agreed between supplier and customer, but does define 3 tightness classes.
When necessary, this European Standard is also applicable to packings used on other rotary equipment such as mixers and agitators.
