Features & Benefits
  • Double-Suction Design provides balanced hydraulic loads by channeling incoming flow to the screw inlets at each end of the pump
  • External Bearings and AGMA 11 Timing Gears are in separate oil reservoirs to eliminate exposure to the pumped fluid
  • Versatile ISO 21049/API 682 Seal Chamber readily accommodates multiple seal types and meets HSE regulations without modification
  • Split Bearing Bracket Construction facilitates easy maintenance of individual bearings and mechanical seals
  • Modular Non-Welded Casing is available in multiple standard and specialty alloys
  • Nozzles integral to the outer casing insulate the inner casing from piping loads, helping to maintain a non-contacting shaft design
  • Screws integral with shaft to prevent deflection during high loading
