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
as amended.
For relationship with EU Regulations see informative Annex ZA, which is an integral part of this
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.

4.1.1 Working pressure
4.1.1.1 The pump shall meet the requirements of 4.1.1.2 to 4.1.1.4.
The performance shall be expressed as the working pressure in bar.
4.1.1.2 The maximum allowable casing working pressure shall be specified by the manufacturer and
shall be at least equal to the closed valve pressure at maximum rotational speed and maximum impeller
diameter plus maximum inlet pressure.
4.1.1.3 The assembled pump shall withstand internal hydrostatic pressure and meet the requirements
of EN 12162:2001+A1:2009 when tested in accordance with 5.1.1.1.
4.1.1.4 The pump casing shall withstand the hydrostatic pressure test without rupture in accordance
with EN 12162:2001+A1:2009 when tested in accordance with 5.1.1.2.
