FEATURES:
Discharge: Heavy-duty cast iron construction provides smooth water passage to column pipe. NPT threads standard.
Pump Bowls: Highly efficient hydraulic design…threaded bowl design in gray cast iron.
Impellers: 20% glass-reinforced Noryl to resist abrasives and provide smooth water passage for minimal friction loss.
Upthrust Bearing: Nylatron upthrust bearing provides positive momentary upthrust protection during start-up.
Diffuser Bearing: Bearings at each stage provide radial protection and stability, and excellent resistance to sand damage.
Bowl and Intake Bearings: Fluted, cutless rubber type assures superior abrasive handling characteristics, located at each stage.
Stainless Steel Pump Shaft: Stainless Steel Pump Shaft: 300 grade “treated” stainless steel pump shaft is corrosion-resistant. The hex shape offers generous impeller drive surfaces.
Intake Screen: Stainless steel material offers maximum corrosion resistance… protects against damaging solids entering the pump assembly.
Motor Bracket: Incorporates an efficient hydraulic design for maximum volume and access to motor mounting nuts.
Pump/Motor Coupling: Pressed-on, sintered 300 grade stainless steel for maximum corrosion resistance provides trouble-free transfer of power between motor and pump shaft.
