How we handle WEG requests
WEG electric motors (W-series, e.g. W21) are frequently paired with pumps and other rotating equipment as replacement or original-fit drive units. Frame size, power rating, RPM and voltage/frequency (many marine applications run 440V/60Hz three-phase) together determine whether a motor is a direct fit or needs adaptation — those four figures from the nameplate are the fastest way to confirm compatibility.
Customers can send part numbers, maker references, equipment model data, serial numbers, nameplates, photos, drawings, old offers or previous supply documents. We review the information before quoting so the request is handled as a technical procurement task rather than a generic product search.
Brand names on this page are used only to identify equipment, models, parts and buyer search references.
Parts and equipment we can review
WEG RFQ scope
Use this page when your purchasing or engineering team needs review by part number, model, serial number, drawing, photo or old commercial reference.
pump-mounted motor replacements
Pump-mounted motor replacements are checked against the pump model, shaft size and material, since impeller profiles vary by casting revision.
frame size and mounting verification
Frame size and mounting verification are reviewed against maker reference, equipment model and any photos or drawings you can send.
voltage/frequency configuration (e.g. 440V/60Hz)
We check voltage/frequency configuration (e.g. 440V/60Hz) against maker data, dimensions and delivery need before sourcing.
bearing and winding service parts
For bearing and winding service parts, dimensions and any visible marking on the old part let us check equivalents quickly.

How to send a useful WEG RFQ
Attach the clearest technical information available. A single photo of a nameplate, an old offer line or a marked drawing can prevent delays when there are similar models, revisions or connection types.
If the item is obsolete or hard to identify, include dimensions, application notes and any alternative references already checked by your engineering team. We can review the request and reply by email with the next steps.
