SPX Flow’s ClydeUnion pump CUP-BB5 range with its cartridge retention design, allows a complete rotor change-out in under eight hours for applications in the oil and gas industry.
The CUP-BB5 range comprises radially split, diffuser type, multi-stage pumps. With capacities up to 2,800 m3/hr (2,330 USgpm) and delivery heads up to 4,100 m (13,450 ft), typical applications for the CUP-BB5 range include produced water injection, seawater injection and main oil lines.
CUP-BB5 pumps do not require any specialist tools or additional training and the Shear Ring locking system eliminates the need for high torque equipment to assemble or dis-assemble.
With two main variants of in-line impellers (CUP-BB5i) or a back-to-back impeller arrangement (CUP-BB5b) the pumps can be engineered to order and are fully compliant with the latest API 610 and API 682 requirements.
For specific applications SPX Flow can offer a dynamically stiff rotor design. This rotor design is based on achieving maximum sustainable hydraulic efficiency, extending mean time between overhauls and delivering reliability in operation. The resulting high critical speed margins and low static deflections reduce internal wear and increase reliability.
