Baker Hughes centrifugal pumps

Specify a Baker Hughes industrial centrifugal pump from the process duty and installation. Identify components for an existing machine from markings and drawings.

BB1 DVS, DVE and BFD

Between-bearing pumps with an axially split housing. DVS and DVE have one stage; BFD has two. Identify the installed machine before specifying replacement components.

API 610 BB1 family
DVS for heavy-duty service
DVE for medium-duty service
BFD with two stages

BB2 DVSHF, THF and DS-THF

Radially split pumps for continuous process duty. DVSHF is single-stage; THF and DS-THF are two-stage designs. Check the installed seal arrangement against machine documents.

Define the equipment and supply scope

The Baker Hughes industrial centrifugal-pump portfolio covers single-stage and multistage equipment, horizontal and vertical installations, and single- or double-housing designs. Applications include process plants, pipelines, power generation and industrial water systems.

Start a project with the actual fluid-handling duty and a defined installation. The name of a complete pumping package may differ from the designation on the pump itself.

State whether the enquiry concerns a new pump, replacement of an installed machine or maintenance components. Provide an equipment list and identify the interfaces that will remain in service. For a complete package, separate the pump, driver, coupling and auxiliaries in the scope table.

This makes proposals comparable against a common requirement.

Prepare the hydraulic duty data

Submit the fluid name, required capacity and differential head, or the applicable suction and discharge pressures. Preserve units and distinguish normal, minimum and maximum operating conditions where the project defines them.

Include temperature, density, viscosity and information about solids or other constituents from the approved process documents. Mark the source and revision of the data sheet.

Provide the available suction conditions and the project requirements for installation and operation. If a value is unavailable, identify the field for technical clarification. Keep the current operating conditions separate from the proposed future duty.

A family name or catalogue limit alone does not describe the operating point of a particular machine.

Select between the BB pump families

BB1 includes the DVS, DVE and BFD designs. BB2 includes DVSHF, THF and DS-THF, while MSN and MSN-D appear in the multistage axially split portfolio. BB4 DDHF-R is a ring-section design.

BB5 DDHF uses a double-housing barrel arrangement, and DDHFM addresses duties including onshore and offshore water injection. Retain the precise family designation throughout the enquiry.

For an existing machine, use the installed configuration and serial number rather than choosing components from a general family description. For new equipment, describe the required process duty and package boundaries.

Record construction requirements in the project specification and separate mandatory requirements from options. Confirm the selected arrangement in the final technical scope.

Vertical and overhung configurations

The overhung portfolio includes TC, VP and DSVP, with horizontal and vertical configurations. Vertical industrial families include VD, VDA, VSA, VCD, DSVCD, VMS and VCMS. The manufacturer lists diffuser-bowl and volute arrangements in its industrial portfolio.

Use these references to identify the relevant equipment group before developing the installation specification.

For a vertical replacement, provide the general arrangement, column dimensions and discharge arrangement. Identify the retained structure and the components included in the proposed replacement. For overhung equipment, include orientation and connection drawings.

Photographs support the installation records, while dimensions and interface requirements should remain linked to controlled drawings.

Driver and auxiliary-system requirements

Specify the driver arrangement and the applicable electrical supply or other project drive requirements. Include speed-control requirements where they form part of the project.

List the baseplate, coupling, lubrication equipment, seal-support equipment, instruments and other auxiliaries to be included. Identify separately the existing items that are intended to remain in service.

For DDHFM water-injection projects, define main and booster pump duties together. For other packages, provide the relevant process and equipment interfaces from the installation documents. Draw a clear boundary between the proposed supply and work performed at the plant.

Keep instrument and accessory references separate from the main pump designation.

Identify parts for an installed pump

Provide a readable nameplate, serial number and complete model designation, retaining suffixes and punctuation. Attach the assembly drawing and parts list with the required item marked. For several machines, group the requirement by serial number and connect each attachment to the relevant line.

An internal plant tag can be retained as an additional reference.

Where equipment has been modified, identify the changed assemblies and use the current documentation. A previously purchased component can support identification when its confirmed relationship to the machine is recorded. Keep warehouse codes alongside the equipment references.

Separate a complete assembly, a maintenance set and individual components in the procurement table.

Impellers, internal bundles and rotors

For an impeller, specify its drawing position, stage location and available part reference. For a multistage rotor, distinguish the bare shaft, assembled rotor and individual components. Define the contents of an internal bundle using its assembly documents.

Provide quantities separately for each item and retain the relationship between a part and its installed machine.

When measurements come from a worn component, identify them as measured values and keep them separate from drawing dimensions. Attach photographs showing markings and the damaged area. Any proposed change in material, geometry or configuration should be identified for technical agreement.

A request to repeat an existing item should use the current confirmed specification.

Seals, bearings and connected equipment

For a mechanical seal, include the seal manufacturer, model and cartridge markings as well as the pump identification. Attach the support-system drawing where relevant.

The manufacturer describes BB2 seal chambers for API 682 arrangements, while the actual installed seal must be established from machine records. Distinguish a complete seal, a repair set and separately required elements.

For a bearing assembly, identify the drive or opposite side, housing reference and available bearing marking. List associated components from the drawing. Lubrication and seal-support equipment may carry their own references, particularly after maintenance changes.

Include those markings rather than relying on the pump name to identify every connected component.

Replacement projects and installation interfaces

Provide foundation, nozzle and driver connection information when replacing an installed pump. Mark the interfaces and space restrictions that the project must retain.

Show the existing machine and proposed future duty separately, since process requirements may have changed after initial installation. Include the drawing revision and photographs of the complete arrangement.

List retained drivers, couplings, frames, instruments and support lines where applicable. Each interface should point to the document used for its assessment. Record changes to the duty or package layout explicitly.

Review quotations against the same equipment list so that a different scope is identified before technical and procurement decisions are made.

Procurement documents and receiving checks

State documentation, marking and inspection requirements in the enquiry. Identify the document language, item-reference rules and links to plant equipment numbers. Where a specific material is required, attach the applicable component specification.

Keep technical questions associated with individual lines and drawing revisions so agreed details remain traceable through later amendments.

On receipt, compare markings, quantities and assembly contents against the agreed specification. File the documents with the corresponding pump records and retain the confirmed component references for subsequent maintenance.

Installation and commissioning follow the applicable equipment documents and plant procedures. To begin selection, send the equipment identification, duty or parts list, supporting drawings, quantities, delivery location and a technical contact.
