API 610 categorizes centrifugal pumps into three primary groups: OH, BB, and VS.
- OH – Overhung pumps: In these pumps, the impellers extend beyond a radial bearing. The support system must handle all forces, encompassing the overhung mass, as well as rotor dynamic and hydraulic forces.
- BB – Between bearing pumps: These pumps have their impellers suspended between two supports, with the impeller placed horizontally, aligning with the bearings.
- VS – Vertically suspended pumps: Casing and impellers of these pumps are submerged in the pumped fluid, suspended on a vertical column under a support plate atop the tank, where the motor and thrust bearing are mounted.
These three API 610 pump types find application across various scenarios:
- OH – Overhung pumps: Produced Water; Feed Pump; Booster Pump; Hydrocarbon Transfer; Condensate.
- BB – Between bearing pumps: Cooling Water; Boiler Feed; Well Injection; Feed Water; Crude Transfer
- VS – Vertically suspended pumps: Open Drain; Closed Drain; Crude Oil Transfer; Firewater; Seawater Lift"
