Pillar fire hydrants for a safer environment
All PAM cast iron fire hydrants are in strict compliance with standards NF EN 14384, NF S 61213/CN and the CE mark. A casing made entirely of ductile iron protects them from impact, whether accidental or otherwise, and operational hazards such as water hammers. Their internal and external coatings are a 250-micron thick layer of epoxy powder, while the resistance of the final coat to ultra-violet light protects the pillars against external pressures.
We equip all of our pillar fire hydrants with a sealing check valve, which is fully encapsulated in elastomer to protect it from corrosion and abrasion. Its shape prevents the retention of sand or gravel, thus avoiding damage, and ensures that the flow rate at opening and closing is progressive so that water hammer is avoided.
The complete range of PAM pillar fire hydrants comes in two versions – collapsible and non-collapsible. Impacts that knock the pillar hydrant over are not detrimental to it, as it is equipped to remain watertight. Only the assembly wedges are damaged in this instance and the hydrant can be put back into service quickly, easily and economically. The fire hydrants are built to prevent any leakage, which could lead to erosion or black ice.
