Features & Benefits
  • Double Volute, Axially Split Casing Design minimizes hydraulic radial forces in any condition down to the minimum flow
  • Suction and Discharge Nozzles are integrally cast in the lower casing half to permit pump disassembly without disturbing the piping
  • Near Centerline Mounting provides superior pump alignment and performance at elevated temperatures
  • Double Suction Impeller provides hydraulic axial balance and allows minimal NPSHr. ISO 21049/API 682 Seal Chambers ensure ample flow around the seal faces and accommodate numerous seal designs
  • Heavy-Duty Shaft Design ensures trouble-free operation below the first critical speed
  • Standard Renewable Casing and Impeller Wear Rings provide hydraulic stability and high operating efficiency
