Abstract

This draft European Standard establishes general principles for the construction, use and testing of circulation pumps having a rated power input P1 <= 200 W, intended to be used in heating installations and domestic hot water service installations. The requirements of this European Standard 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 not covered by this European Standard. Together with EN 809:1998 this European Standard covers the mechanical aspects of safety and performance for circulation pumps. As regards safety requirements for electrotechnical parts of circulation pumps EN 60 335-2-51:1991 applies. All known hazards which are likely to occur at normal installation and operation are covered by this European Standard. This European Standard does not contain any requirements and tests for airborne and structureborne noise emission. These items are going to be dealt with in an amendment. This European Standard applies to: a) A.C. circulation pumps having a rated power input P1 <= 200 W intended to be used in ordinary heating water systems with a maximum permissible inlet temperature of TF <= 110 °C and a maximum outlet working pressure p2maxo <= 6 bar. b) A.C. circulation pumps having a rated power input P1 <= 200 W intended to be used in domestic hot water installations with a permissible inlet temperature of TF <= 65 °C and a maximum outlet working pressure p2maxo <= 10 bar. The technical specifications given in this European Standard are limited to apply only to circulation pumps of the glandless type. This European Standard applies to circulation pumps which are manufactured after the date of issue of this European Standard.
