Worthington® BP Diffuser Casing, Multistage, Process Barrel Pump ISO 13709/API 610 (BB5)

Optimized Multi-Vane Diffuser and Channel Ring Design results in balanced radial loads and precise hydraulic performance over the entire flow range, including partial-load operation.

Tandem Impeller Design increases rotor stability and facilitates maintenance by permitting replacement of a single casing stage.

Dynamically Balanced Impellers are precision cast to improve hydraulic efficiency and performance repeatability.

Straight Style Balance Drum simplifies assembly since no axial setting is required.
