  • 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 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.
