BS EN 1151-1:2006 Pumps — Rotodynamic pumps — Circulation pumps having a rated power input not exceeding 200 W for heating installations and domestic hot water installations — Part 1: Non-automatic circulation pumps, requirements, testing, marking
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.
As regards safety for electrotechnical parts of circulation pumps, EN 60335-2-51 applies.
