Pump spare parts should be identified by manufacturer, complete pump model and the required service reference. The brand narrows the search, but does not establish compatibility by itself.
Use the UMYTEC spare-kit finder to begin identifying listed HAWK, Interpump and UDOR parts. For other models, including CAT Pumps, check the exact published part reference or send the nameplate for identification. A finder result is a selection aid rather than confirmation of every production version.
How do you identify pump spare parts by brand?
Copy the full nameplate information, including spaces, letters and suffixes. Then identify whether you need water seals, valves, oil seals, ceramic plungers or another component. Use the manufacturer’s exploded drawing to connect the fault location with the correct part reference.
For example, “HAWK pump seals” is too broad for ordering. A full model code, the service group and any required plunger diameter provide a much stronger basis. Keep the old kit packaging when available, but check whether the current parts list still assigns that reference to the pump.
Can parts be shared between brands or similar models?
Only use a cross-reference that has been verified for the exact application. Similar external dimensions do not prove that seal profiles, valve seats, materials and operating limits are equivalent.
The same caution applies within one brand. Two pumps may look alike yet have different internal parts. Never select a ceramic plunger by diameter alone: length, end geometry and mounting details can also matter. A replacement must satisfy the complete part specification.
What information speeds up identification?
Prepare a clear nameplate photograph, the machine’s application, symptoms and photographs of the removed part if available. Include the serial number or production code where the drawing uses it to distinguish versions.
For a recurring maintenance order, maintain a record linking each machine to its pump model, drawing revision, kit reference and number of kits used. This prevents a later technician from ordering a familiar-looking set for a different pump installed elsewhere on the site.
Selection reference
| Information | Purpose |
|---|---|
| Pump brand and full code | Identifies the manufacturer and model |
| Suffix and production data | Separates versions where relevant |
| Required service group | Selects seals, valves, plungers or other parts |
| Kit reference and coverage | Confirms both identity and order quantity |
Conclusion
Search by brand, then verify the exact model and part number. Confirm stock and delivery for the identified item rather than assuming all parts for a brand have the same availability.
Frequently asked questions
Is the brand enough to order a kit?
No. You need the full pump model and the correct service reference.
Does the spare-kit finder cover every manufacturer?
Its published tables describe its coverage; verify unlisted models separately.
Can I use a kit for a similar-looking pump?
Only with a verified compatibility reference.
Is a pump suffix optional?
No. Record it because it may distinguish important construction differences.
Can an old kit number be useful?
Yes, but check it against the current parts list and exact pump version.
Does one brand use one plunger diameter?
No. Diameter varies by family and model.
Are all spare parts sold as complete kits?
No. Some are supplied individually or in different service sets.
Can I assume every part is original?
Check the individual listing and manufacturer reference; do not infer origin from appearance.
What if the nameplate is unreadable?
Provide photographs, dimensions and any machine documentation; identification may require additional checks.
Should my maintenance list include quantities?
Yes. Record the number of kits or individual parts needed per pump.

AI Summary
Pump spare parts are matched by brand, full model, production version and service reference. Avoid unverified cross-brand substitutions. A maintenance record containing the exact kit and quantity makes repeat ordering more reliable.
