CEN/TC 197/SC 4/WG 1 - Circulation pumps

This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators with pump housing having a rated power input P1 ≤ 200W, intended to be used in heating installations, domestic hot water service installations and cooling systems, and is limited to glandless circulators with threaded connections of 11/2 inch. The test code comprises the test rig, the measurement method and the test conditions.
This European Standard applies to glandless circulators, which are manufactured after the date of issue of this European Standard.
The characterization principle is based on measuring the structure-borne and the fluid-borne power transmitted respectively by vibration and pressure fluctuations in the pipe connected to a glandless circulator.

This European Standard specifies general performance requirements and general requirements and procedures for testing and calculation of the energy efficiency index (EEI) for glandless circulators having a rated hydraulic output power of between 1 W and 2500 W designed for use in heating systems or cooling distribution systems.
All known hazards which are likely to occur at normal installation and operation are covered by the European Standards EN 809 and EN 60335-2-51.
As regards safety for electro-technical parts of circulators, EN 60335-2-51 applies.

This European Standard specifies the procedure for calculating the energy efficiency index (EEI) of circulators integrated in products.

This European Standard specifies the procedure for calculating the energy efficiency index (EEI) of standalone circulators.

Specifies the main parameters and describes the pump designation which consits of three numbers. The table covers flange sizes from 50 mm up to and including 200 mm. A figure shows the side view and the front view of the pump.

Specifies basic dimensions and gives alternative numbers and locations of baseplate fixing holes to suit individual installations. Covers the baseplate numbers from 2 to 9. The data given are intended primarily for use with pumps in accordance with ISO 2858, coupled to foot-mounted electric motors for installation on a foundation.

CMC/TC - Title page/Foreword - Deletion of the superseding note, mistake happened by writing the comment "Revision of EN 1151:1999 into 2 parts (see also WI 053)." into the database. The superseding notes have been added and extended during each publication step and it has always been missed to correct even during CA/7 publication.

This part of EN 1151 specifies a test code for the vibro-acoustic characterisation of circulation pumps as defined in EN 1151-1, and is limited to circulation pumps with threaded connections of 1½ inch. The test code comprises the test rig, the measurement method and the test conditions.
The characterisation principle is based on measuring the structure-borne and the fluid-borne power transmitted respectively by vibration and pressure fluctuations in the pipe connected to a circulation pump.

This part of EN 1151 establishes general principles for the construction, use and testing of circulation pumps of the glandless type, having a rated power input P1 £ 200 W, intended to be used in heating installations and domestic hot water service installations.
NOTE   The requirements of this document may apply to circulation pumps for domestic use having a rated power input above 200 W up to and including 300 W. However, this decision depends on agreement between the supplier and purchaser.
Circulation pumps with a rated power input above 200 W for professional/commercial use are excluded from the scope of this document.
This document applies to:
a)   A.C. circulation pumps having a rated power input P1 £ 200 W intended for use in ordinary heating water systems with a maximum permissible inlet temperature of TF £ 110 °C and a maximum outlet working pressure p2max o £ 6 bar.
b)   A.C. circulation pumps having a rated power input P1 £ 200 W intended for use in domestic hot water installations with a permissible inlet temperature of TF £ 65 °C and a maximum outlet working pressure p2max o £ 10 bar.
This document applies to circulation pumps, which are manufactured after the date of issue of this document.
This document covers the performance for circulation pumps. All known hazards which are likely to occur at normal installation and operation are covered by the European Standards EN 809 and EN 60335-2-51:2003.
As regards safety for electrotechnical parts of circulation pumps, EN 60335-2-51:2003 applies.
