- Centerline support for reduced thermally induced misalignment
- Double suction impeller for low NPSH3
- First critical speed is well above operating speed range for smooth operation
- Casing designed for 2 times API 610 nozzle loads for freedom from piping distortions
- Grouted or ungrouted, 1x or 2x nozzle load baseplates for reduced installation cost
BBS and CD between bearings single stage pumps
Customized solutions for high-pressure jobs
The BBS and CD models are API 610 Type BB2, single stage, radially split pumps. They offer the widest range of hydraulic performance in the industry.
- Low pressure unit charge
- Atmospheric or vacuum bottoms
- Fractionator bottoms
- High temperature oil sands processing with abrasive resistant coatings
- Boiler feed booster
The double suction impeller provides reduced NPSH3 for tough services in refineries and other critical applications. The CD can be custom engineered for high pressure, special hydraulics and special nozzle locations.
