M/469 - Circulators

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 the procedure for calculating the energy efficiency index (EEI) of standalone circulators.

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

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.
