Our expertise in designing and manufacturing BB5 pumps dates back to the 1970s, with hundreds of units installed worldwide. This API-compliant BB5 pump range is a radially split, multi-stage, between-bearings, centerline-mounted pump with either a single or double suction first stage impeller for reduced NPSHr. The AHPB has back to back impeller arrangement to minimise thrust loads, and to improve rotor dynamic performance on light SG applications. The design is available with bolted or shear ring end cover arrangements.
