The BBT/BBT-D 2 stage, radially split ISO 13709 / API 610 Type BB2 pumps offers the widest range of hydraulic performance in the industry. The BBT-D double suction impeller provides reduced NPSH3 for tough services in refineries and other critical applications. Main applications are Unit charge, Atmospheric or vacuum bottoms retrofits where Net Positive Suction Head Available (NPSHa) is limited, Fractionator bottoms, Coker heater charge and Boiler feed booster.

  • Centerline support for reduced thermally induced misalignment

  • BBT-D double-suction impeller for low Net Positive Suction Head (NPSH)

  • First critical speed is well above operating speed range for smooth operation

  • Casing designed for 2x API 610 nozzle loads for freedom from piping distortions

  • Grouted or ungrouted, 1x or 2x nozzle load baseplates for reduced installation cost
