BED/BDG IS BB5 type horizontal multistage ring section pump, be used as high pressure pumps that is designed according to API610 10th. The impellers are stacked back to back symmetrically , therefore the axial hydraulic thrust is automatically balanced. Because of the balance drum being canceled, the maintenance cost is reduced and the working is more reliable. The rotors are perfectly dynamically balanced and the maximum stages can be up to 16stages. EDG/EDF type multistage ring section pump is the ideal high pressure pump for your high pressure application.
