  • Maximum Working Pressure : 17.5 Bar (250 Psi)
  • Mounting : Vertical

Dry Type Pillar Fire Hydrants

DISCRIPTION

  • 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 B16.5 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.

SPECIFICATION

  • 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 easier. 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 deterioration. O-ring provides second level seal.
  • Safety flange – breaks cleanly to help prevent barrel damage, but strong enough to withstand normal handling. 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.
