- API 610 and API 682 design
- With a suction can
- Condensate and process-fluid applications
- Specify suction conditions and mounting dimensions
CUP-VSM — submersible pumpsets
Single- or multistage centrifugal pumps integrated with a water-filled submersible motor. Typical duties include seawater lift, cooling-water supply and borehole extraction. Identify the pump and motor separately in a replacement enquiry, including the electrical data and required package scope.
- Water-filled submersible motor
- Single- and multistage options
- Offshore and water-intake applications
- Provide electrical ratings and the pumpset scope
Impellers, shafts and spare cartridges
Send rotating-assembly enquiries with the pump number and drawing reference. Distinguish a loose impeller from a rotor or complete internal cartridge, because their supply scope differs. Identify the installed stage count and the purpose of the replacement or maintenance set.
- Model, serial number and drawing item
- Stage count and rotation direction
- Impeller diameter and documented material
- List the components required in a complete cartridge
Seals, bearing assemblies and maintenance sets
For a mechanical seal, bearing support or wear-parts set, provide the assembly specification. Match the construction, materials and mounting dimensions to the actual unit. Describe the observed symptoms so the plant engineer can define the required component scope before ordering.
- Assembly number and section drawing
- Fluid, temperature and seal arrangement
- Bearing support and lubrication configuration
- Itemised consumables list with quantities
Define the pump duty before choosing a series
Start with the required task: a new pumping package, replacement of an installed unit or procurement of maintenance parts. For an existing installation, send the nameplate and equipment documents.
For a new project, provide the pumped fluid, required flow, head, temperature and installation conditions.
OH, BB and VS describe construction families. Retain the full equipment designation, serial number and drawing reference in your enquiry. If the available documents show different revisions, attach them with a note identifying which revision represents the pump currently installed at the plant.
Operating point and fluid specification
State the normal, minimum and maximum flow and head, together with available suction pressure. Add fluid temperature, density, viscosity and information about gas or solids. For water-intake systems, provide water quality and reservoir levels.
These data allow the technical enquiry to describe the actual duty.
When the required operating conditions are changing, include the existing pump curve, impeller diameter and drive rating. Identify whether the enquiry concerns a replacement part for the current build or a hydraulic change for a new duty point. Keep those two scopes separate in the purchasing list.
Identify parts using the installed pump documents
Provide a clear photograph of the complete nameplate, the pump general arrangement and each required drawing item. State quantities separately. For several pumps, use a list linking the equipment number, item designation, part description and quantity.
This keeps every component associated with the correct installed unit.
If a part number is unreadable, add photographs of the mounting interface and any remaining identification. Include the relevant assembly drawing or previous specification.
The plant engineer should define whether the required scope is an individual component, a consumables set or a complete assembly.
Define the scope of a rotor or cartridge
Identify whether the enquiry is for a shaft and impellers, an assembled rotor or a complete spare cartridge. List the components that should be included. For a multistage pump, preserve the stage sequence and first-stage configuration shown in the hydraulic and assembly drawings.
For a planned shutdown, specify the number of pumps to be serviced and the purpose of each maintenance set. Separate installed-unit replacement parts from workshop spares.
State plant requirements for identification, preservation and packing so the supply scope can be checked against the maintenance plan.
Drive and package boundaries
List the pump, driver, coupling and base separately. Specify power supply, operating speed, control method and plant requirements for the motor. A complete replacement package also needs the foundation layout, nozzle orientation and available space. Identify components that will remain in service.
If the existing driver will be reused, attach its rating information and coupling designation. For a new package, define the requested pump, drive, base, instruments and accessories.
A clear scope supports technical comparison of quotations and helps the receiving team prepare an itemised acceptance list.
Materials and service conditions
Retain the materials specified for the casing, shaft, impeller, sleeves and sealing components in the drawings. Provide the fluid composition and relevant corrosion, wear or temperature conditions.
For seawater service, include the project material requirements rather than assigning one material to the whole pump.
If a material change is being considered, describe its purpose and attach the current specification. Identify the required inspection and documentation.
Replacing a component to an existing drawing and changing the pump design are separate engineering scopes that should be reviewed with the responsible plant specialist.
Documents for technical and purchasing review
Attach the pump data sheet, general arrangement, assembly drawings and itemised specification. For a new pumping installation, include the project enquiry sheet.
Identify documents required before ordering for engineering approval, as well as documents that should accompany the supplied equipment or maintenance components.
Use consistent designations and units throughout the list. Preserve original drawing values when a different unit system is used. State common requirements once, then record differences in material, quantity or supply scope beside the relevant items.
This helps technical and purchasing teams review the same equipment definition.
Send an equipment or maintenance enquiry
Choose a pump family or a maintenance component and open the enquiry form. Enter the full model, pump number, quantities and purpose of the request. Attach drawings or photographs. For a long parts list, use a separate file and summarise the requested scope in the message.
A new installation benefits from an enquiry sheet; a maintenance request benefits from an inspection report and component specification. State the delivery destination and a technical contact at the plant.
The supply scope can then be clarified item by item against the documents provided for engineering review.
Availability, price, delivery, documents and compatibility require confirmation for each enquiry. This page does not establish authorised dealership, certified servicing or identical performance across every configuration in a pump family.
