Dry Pillar Fire Hydrants (UL/ FM Approved)

• NAFFCO Fire Hydrants are designed to comply with ANSI/ AWWA C502.
• Dry barrel design eliminates damage to the hydrant caused by freezing of the upper part.
• NAFFCO Fire Hydrants are designed for high performance and easy to install, maintain and repair.
• Excellent and proven flow characteristics.
• 2 x 2½” NH thread connectors for soft hose connection.
• 1 x 4½” NH thread pumper connection for fire trucks.
• 6” inlet connection complying to mechanical joint ANSI/ AWWA C111/A21.11 or flange connection ASME 5 Class 150.
• Operation threads are corrosion protected and for easy operation.
• NAFFCO fire hydrants are high pressure rated to 250 psi compatible with today’s trends.
• Internal epoxy paint system gives high corrosion protection to hydrants.
• Advanced safety couplings and flange design reduces traffic damage to hydrant.
• Main valve is easily removed from either the bonnet flange or ground line flange.

DESIGN FEATURES

• Body Material: Ductile Iron.
• Nominal Pressure 250 PSI , Test Pressure: 500 PSI.
• O-ring sealed flanges at the bonnet ground line and shoe simplify maintenance by eliminating gasket adhesion at these points, making disassembly The O-rings are easier than flat gaskets to position during reassembly, and provide superior pressure handling.
• Hold-down nut - features integral weather seal. Prevents unauthorized removal of hold-down nut or operating nut. Resilient wiper seal prevents water entry and protects from freezing; material resistant to sunlight O-ring provides second level seal.
• Safety flange - breaks cleanly to help prevent barrel damage, but strong enough to withstand normal Allows economical repair, adding of extension section, rotation or changing of upper barrel without excavation.
• Full flow openings - large, smooth radius hose and pumper openings reduce friction loss.
