Double Suction Pumps

BBS API 610 BB2 pumps are used mostly in process applications in refineries and petrochemical plants. The broad capabilities of this design allow it to be used in the most arduous applications, such as high temperatures and pressures, while still providing long life and trouble free service. The double entry impeller is particularly suited to low NPSHA applications.
