Horizontal, single- and two-stage, radially split, double-suction BB2 pumps according to API 610 are designed for the most demanding operating conditions in the oil, gas, energy and process industries. They feature a radially split casing (i.e. transverse to the shaft axis) and a rotor mounted between the bearings. This configuration provides maximum stability at high pressures, temperatures and long running times.

The centreline-mounted casing design safely absorbs thermal expansion and maintains system alignment even under high-temperature conditions. The pumps are available in single- or two-stage versions with single or double suction impellers. BB2 pumps cover a wide range of delivery heads and are suitable for a variety of critical process tasks.

Apollo Gößnitz offers BB2 pumps in various configurations, including single-stage, radially split spiral casing pumps with double volutes and double suction impellers, and specialised high-performance variants with an axial inlet and semi-open impellers in a two-stage back-to-back design in accordance with API 610. Vertical versions with bearings on both sides are also available.

Thanks to their robust construction, API compliance and high mechanical stability, BB2 pumps are ideal for demanding processes such as oil and product pipelines, refinery and petrochemical applications, water injection, boiler feed water and other high-pressure, high-temperature services.
