Standards

SAINT-GOBAIN PAM underground fire hydrant DN100 is in accordance with Standards NF EN 14339, NF S 61211/CN.

The surface box is designed for a resistance to the live loads defined by the class C 250 according to the standard NF EN 124.

Marking

  • Foundry marking on the body : DN100 PN16
  • Foundry marking on the cap: SG PAM logo Arrow indicating the opening direction Number of turns necessary to obtain a complete opening
  • On an aluminium plate stuck on the cap: Commercial reference The year of manufacture
  • On a label stuck on the body: the good position of the pipe in order to guarantee the position of KEYSER outlet and thus the correct assembly with the material of the firemen (bends).

Alimentarity

The hydrant is in conformity with the French regulation: alimentary certificate (ACS).

Technical characteristics

  • Operating of the hydrant: Operating square cap 30 x 30 mm
  • Closing direction: clockwise
  • Operating turns: 13
  • Kv Coefficient: 190 mini
  • Outlet Type Keyser 4’’
  • Flanges ISO PN10/16
  • Maximum allowable pressure (PFA):
  • Factory test pressure: body: 25 bars shutter: 17,6 bars

Hydraulic characteristics

The system of obturator is especially designed so that the flow is established in a progressive way with the opening, thus avoiding the risks of water hammer.

Independent surface box without maintenance

The system of opening of the surface box (patented): the complete absence of hinge allows many openings and closings of the surface box without particular maintenance.

The strains on the surface box which is completely independent are entirely absorbed by the ground and not by the hydrant. The sealing of the junction with the water pipeline is kept.

The surface box is in conformity with the European Standard EN 124. Class C 250 (load 250 kN)
