Opposed Impeller Design helps to balance residual axial thrust while producing ultra-high pressures.

Inner Casing is normally provided with a bolted head at one end. It is also available in a cartridge element design for quick change out in the field, or shear ring (no bolts) design.

Heavy-Duty Barrel with Discharge Cover is made of forged steel and incorporates ASME Section VIII design criteria and pressure ratings based on process requirement.

Radially Split Inner Casings are multi-vane diffuser/channel ring design, and are precision cast and milled to optimize repeatability of performance. They provide metal-to-metal sealing surfaces between stages and between the inner and outer casing.

Straight Style Balance Drum handles axial thrust across the full operating range. The drum is located with a split ring and interference fit, and is keyed to the shaft.

Large Diameter Shafts are incrementally stepped at all impeller, seal and thrust collar fits for ease of assembly.

Operating Parameters

  • Flows to 4000 m3/h (17 610 gpm)

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

Description: Fully compliant with the latest edition of ISO 13709/API 610 (BB5), the BP is a diffuser style pump that is well-suited for high temperature and high pressure services. In particular, it is ideal for boiler feed, descaling, decoking and reactor charge applications.

WXB Between Bearings, Diffuser Casing, Multistage, Process Barrel Pump

Description: The WXB is a multistage, diffuser-casing barrel pump with tandem impellers and a balance drum to carry axial thrust forces. It is designed for users who need the hydraulic range and performance of a ring section pump, but demand the design and maintenance attributes of a barrel pump.

HDO (HSO) ISO 13709/API 610 (BB5) Between Bearings Volute Casing, Multistage, Process Barrel Pump

Description: Rated for discharge pressures to 450 bar (6600 psi),HSO/HDO pumps are manufactured to customer specifications, often exceeding ISO 13709/API 610 (BB5). These pumps feature opposed impellers and dual volute designs, resulting in nearly balanced axial hydraulic thrust over the full operating range of the pumps. • HSO: Single suction, first stage impeller • HDO: Double suction, first stage impeller

WCC 13709/API 610 (BB5) Between Bearings, Diffuser Casing, Multistage Process Barrel Pump

Description: The WCC is a multistage, diffuser type barrel pump with a tandem impeller rotor and a single-diameter balance drum to compensate for residual axial thrust. The radially split inner element facilitates inspection and rapid changeout with a spare.
