UL FM fireriser dry barrel fire hydrant, 250 psi working pressure. Ductile iron barrel, nozzle, bonnet and base with stainless steel stem coupling; multiple bury depths; standard pumper and hose nozzles; internal and external polyester coating RAL3002, flanged to ANSI / EN1092-2 PN16 for municipal and industrial fire protection systems.
The UL FM Fireriser Dry Barrel Fire Hydrant 250PSI is designed for reliable fire water supply in harsh outdoor climates. The dry barrel construction keeps the main valve and upper barrel free of standing water when the hydrant is closed, reducing the risk of freezing and internal corrosion.
The hydrant design complies with AWWA C502, FM1510 and UL246, using standard pumper outlets (4" / 4.5") and threaded hose nozzles (2.5") with NFPA1963 thread standard. Multiple bury-depth options allow the same hydrant model to suit different pipe cover requirements, while internal and external polyester coating to RAL3002 provides long-term corrosion protection.
Mechanical joints are designed to ANSI / AWWA C111 / A21.11 and AWWA C153 / A21.53. The inlet flange is drilled to ANSI B16.1 Class 125 / ANSI B16.5 Class 150 / EN1092-2 PN16, making the hydrant compatible with common global piping standards.
With a working pressure of 250 psi and temperature range from –10°C to 100°C, this UL Listed and FM Approved dry barrel fire hydrant is ideal for city mains, industrial plants, tank farms and campus networks supplied by a professional China fire hydrant manufacturer.
