A good choice on a long term period

SG PAM Fire Hydrants are designed to last in time without particular intervention; their functionalities are kept even after many years of use.

The product was qualified in our PAM Laboratory accredited COFRAC.

The product offers higher performances compared to the requirements of the standards:

• a number of opening and closing higher than the 1,000 necessary cycles;

• a resistance of the envelope to the pressure higher than 25 bars;

• easily manoeuvrable with operating torques lower than 80 Nm.

A pleasant design

SG PAM designed the Fire Hydrant ATLAS + to integrate perfectly the urban landscape and to bring a little modernity and a contemporary design: slim and purified lines, soft and continuous forms, alliance of the red and the metallised grey.

Technical characteristics

Fire hydrant operating:

  • Square: 30 x 30mm
  • Closing direction: clockwise
  • Number of revolutions: 13
  • Kv coefficient: 160 (on the central outlet)
  • Outlets diameter: 2 outlets Ø65 and 1 outlet Ø100 symmetric
  • Connecting flange: drilling ISO PN10/16
  • Allowable operating pressure (PFA): 16 bars
  • Factory test pressure: - Body: 25 bars - Plug: 18 bars

Hydraulic performances

Flow of the pillar hydrant ALTAS + non traffic DN100 according to the number of operating revolutions and creating a pressure loss of 1 bar with full opening.

Reliable and perennial closing system

The closing system used with the products of the fire network was designed to guarantee the maximum security.

Easy draining without maintenance

Automatic draining.

The fire hydrant equipped with a plug must be completely empty after use to avoid the risks of freezing in winter. SG PAM developed a completely automatic system of draining made up of a simple opening integrated in the ductile iron of the valve box.

Single design without component: no maintenance, perennial operation, no spare parts.

Fire hydrant in closed position (drawing 1) : the valve releases the opening of draining and water is evacuated gravitationally.

Fire hydrant in opened position (drawing 2) : the valve closes the draining from the beginning of the opening to the total opening. There is no loss of water during the opening operation.

Progressive and durable valve

Valve made up of two ductile iron parts covered with EPDM. This technology enables a perennial tightness.

During the closing operation, the two parts approach by compressing the EPDM to have a durable tightness.

The closing system has been studied so that the flow is established in a progressive way at the opening and closing of the fire hydrant to avoid any risks of water hammer (sinusoidal tightness line).

Closing system with right geometry to avoid its blocking by possible foreign elements contained in water (stones for example) which could involve a tightness defect.

A great simplicity of installation and use

The fire hydrant was designed with a mobile flange at the level of the duckfoot bend to be able to adjust the fire hydrant direction compared to its environment.

Installation of the fire hydrant in conformity with Standard NF S 62 200 and the regulations of the Book of the General Technical Specifications at the Public Markets of Works (fascicule 71)

Earthwork is not necessary and the fire hydrants are directional on 360°.

The smooth barrel without bolt avoids the problems of corrosion of the fire hydrant, and is integrated directly in the ground, which makes it possible to simplify works of completion or landscape installation surrounding.

On this drawing it’s necessary to underline:

  • the use of an adjustment ‘S’ Bend in order to put the hydrant at the good level ;
  • the draining material around the drain ;
  • the block of the duckfoot bend ;
  • the short flanged pipe or a piece of pipe with assembling pieces to respect a distance of 1 m minimum (from axis to axis) between the fire hydrant and the valve or 3 m minimum if the valve is in the axis of the front outlet of the fire hydrant.
