Single Stage Pumps

BBS Between Bearings Single Stage Pumps

BBS

BBS ISO 13709 (API 610 BB2) pumps are primarily used in process applications in refineries and petrochemical plants. The broad pressure and temperature capabilities of this design allow it to be used in the most arduous applications while still providing long and trouble free service. The double entry impeller is particularly suited to low NPSHA applications.
These pumps are also used for main Heat Transfer Fluid (HTF) circulation in solar power plants.
