Automatic firefighting unit 1 KDN Compact EN 12845

Diesel and electric motor fire-fighting sets, ideal for automatic sprinkler systems and/or hydrants of commercial buildings. Designed to be coupled with each other, in order to obtain all the versions and meet all the requirements of the EN 12845 and UNI 10779 standards. By means of a elastic spacer coupling, the pump is coupled to an electric (efficiency level IE3) or Diesel motor capable of providing the power absorbed by the pump at any pump load condition, from no-load, to a load corresponding to NPSH16m (as requested by section 10.1 of the UNI EN 12845 standard). • Modular design: The UNI EN 12845 DAB fire-fighting sets are supplied in modular version. This setup facilitates transport, and the installation of DAB fire-fighting pump sets in pump rooms, even with narrow access doors. Thanks to a coupling kit (supplied as accessory), it is possible to obtain all the compositions contemplated by the standard (one, two, or three electric or Diesel pumps, with or without jockey pump). FLOODED SUCTION INSTALLATION The standards set down, in order of preference, the various ways in which a pump for a fire-fighting set can be installed. End-suction horizontal pumps must be installed with flooded suction whenever possible, and the standard EN12845 clearly defines the parameters for flooded suction installation:- at least two thirds of the actual suction tank capacity must be above the level of the axis of the pump;- the axial line of the pump must not be more than 2 m above the minimum level of water in the supply tank.
