This European Standard deals with the special technical safety requirements for liquid pumps and pump units operating with agrifood-stuff. This European Standard is intended to be used with EN 809 to give the additional requirements for hazards arising from the pumping of substances intended for human and domestic animal consumption (see Clause 4).This European Standard also establishes requirements and/or measures for the reduction of risks during use, including misuse foreseeable by the manufacturer.This European Standard is not intended to be used for pumps and pump units at any stage in the public water supply, nor for pumps handling pharmaceutical products, nor for any other application for which more appropriate standards exist.The pumps and pump units covered by this European Standard are the following:- rotodynamic pumps;- rotary positive displacement pumps;- reciprocating positive displacement pumps.Pumps dealing with agrifood-stuff which are not indicated in this scope are potentially covered by EN 1672-2:2005+A1:2009.This document is not applicable to liquid pumps for agrifoodstuff applications which are manufactured before the date of its publication as an EN.
