The API 610 BB3 pump is a horizontal, axially split, double-casing, opposed-impeller multistage between-bearing pump. The current LUBOR page publishes configurations with different hydraulic sizes and stage counts, with either a single-suction or double-suction first-stage impeller available according to the selected design.
A BB3 pump is typically reviewed for high-head process and transfer duties such as refinery and petrochemical service, pipeline transport, water injection and power-generation applications. Within the wider api 610 pump family, the final hydraulic size, number of stages, material combination and first-stage arrangement should be confirmed from the actual fluid, rated flow, differential head, suction condition, temperature and project specification.

An API 610 BB3 pump should be evaluated when the service requires multistage head generation together with a between-bearing arrangement. Start with rated flow, total differential head, suction pressure or NPSH available, fluid density and vapor pressure, operating temperature, minimum and maximum operating cases, and whether the duty is continuous or intermittent.
| Selection Question | BB3 Pump | Other API 610 Route to Compare | What Buyer Should Confirm |
| Does the duty require multistage high-head generation? | BB3 is a multistage between-bearing route | BB2 may suit different single-stage process duties | Rated/min/max flow, differential head, operating cases |
| Is a barrel-type severe high-pressure arrangement required? | BB3 may still be evaluated depending on duty | BB5 barrel multistage pump should be compared | Pressure level, temperature, project specification, maintainability |
| Is a large single-stage split-case arrangement the better fit? | BB3 is not a single-stage BB1 configuration | BB1 should be compared separately | Flow/head, suction arrangement, installation and service |
| Is first-stage suction performance critical? | Current page publishes single- or double-suction first-stage options | Final selection depends on exact model | NPSH available, suction pressure, fluid vapor pressure, operating temperature |
A bb2 pump, API 610 BB5 or API 610 BB1 may be a better comparison route for different hydraulic or casing requirements, so the final choice should be based on the project duty rather than the BB designation alone.
To evaluate a BB3 pump for high-head multistage service, please provide the actual operating duty rather than only one rated flow and head point.
Hydraulic duty:
• Rated, minimum and maximum flow
• Required differential head
• Suction pressure and NPSH available, if known
• Normal and maximum operating temperature
Fluid data:
• Fluid name and composition
• Density and viscosity
• Vapor pressure
• Solids content, particle information or other special fluid characteristics, if applicable
Project and package requirements:
• Required materials
• Motor power supply and hazardous-area requirement
• Applicable project specification / required API 610 edition, if specified by the project
• Quantity and destination
• Required inspection, performance testing and documentation scope
Providing these duty conditions helps LUBOR evaluate whether the BB3 pump configuration is suitable and prepare a quotation based on the actual operating range rather than a single design point.
Industries Served by the API 610 BB3 Pump
Published application examples on the current page include refined-product pipeline service, LPG pipeline and CO2 injection, boiler feed, water injection, de-aerator water pumping, degassing water pumping and lean-methanol service.
The final suitability of a BB3 pump for any of these duties should be confirmed from the exact fluid, temperature, pressure, NPSH, materials requirement and project specification rather than from the application name alone.
