European foreword
This document (prEN 12259-12:2017) has been prepared by Technical Committee CEN/TC 191 “Fixed
fire fighting systems”, the secretariat of which is held by BSI.
This document is currently submitted to the Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports basic work requirements of Regulation (EU) 305/2011

document.
1 Scope
This part of EN 12259 specifies requirements, test methods, evaluation of conformity and marking of
single stage and multi stage pumps with mechanical seal or soft packing intended to be used in
automatic sprinkler and water spray systems according to EN 12845 and CEN/TS 14816.
This European Standard is applicable for pumps made of the following materials:
• Body: cast iron, cast steel, stainless steel, bronze or aluminium bronze.
• Pump shafts: stainless steel.
• Protective sleeves for shafts, metal parts of mechanical seals, impellers, impeller fastenings
(impeller nuts, locking plates or washers and adjusting springs) and wear rings, including their
counterparts: bronze or stainless steel.
This European Standard is applicable for:
• end suction pumps;
• axial horizontal split case pumps;
• ring section pumps;
• inline pumps (Vertical shaft pump with inlet and outlet in line);
• vertical turbine pumps;
• submersible motor pumps.
