Hydraulic performances
Flow of the pillar hydrant C9 + 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
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.
