STANDARD SPECIFICATION Size: 6NHDH - 6" discharge x 6" suction with 125# cast iron flanges. Impeller - Semi-open, 2 vane: handles 3" solids Volute - Right hand tangential and centerline discharge, eight positions Mechanical Seal or Traditional Packing - Single, type 2, silicon carbide/tungsten carbide mechanical seal: Cycloseal® design, Run-dry available Materials of Construction - Cast iron casing, cast iron impeller - Other materials available, including corrosion resistant materials FEATURES & BENEFITS • Semi-open Impeller • handles difficult to pump liquids, rags, wet straw and other difficult to pump slurries and sludges that other pumps can not handle. • smooth vanes prevent hang-up or “pinning” of stringy materials. • handles slurries and sludges with abrasive partlcles. • no wear rings are required. • no axial clearance adjustments are required. • aids in passing solids through the pump and breaking up larger solids. • resists ragging • TDH to 110 ft., speeds to 1800 RPM or more • handles high head situations and flow rates to 1,800 GPM. • High Efficiencies • due to higher efficiencies, these pumps can often provide significant energy savings and lower operating costs. • Impeller Options • available in 2 or 3 vane impeller design. • Mounting Options • available in a variety of mounting configurations.
