Start with the assembly number
In the URBO UNBT-1180L1 catalogue, document 44024.53.055КДС, the component lists on PDF pages 56 and 58 identify these two groups. Each half has its own reference; the shared description “clamp half” does not make the parts identical.
| Clamp assembly | Half, item 1 | Half, item 2 |
|---|---|---|
| 44013.53.084СБ | 44013.53.085 | 44013.53.086 |
| 44040.53.028СБ | 44040.53.029 | 44041.53.102 |
The first group uses figure 18 for its individual components; the second uses figure 19. Record the figure and item position alongside the number when marking up a drawing.
Keep the complete reference
Copy the original punctuation and Cyrillic СБ suffix in the assembly reference. The table distinguishes the assembly number from the numbers assigned to its halves. Send the actual marking or drawing instead of shortening everything to “44013 clamp”.
These examples belong to the cited UNBT-1180L1 catalogue. For another UNBT model or revision, check its own parts drawing before selecting the assembly. The UNBT mud pump parts category provides the product range; the UNBT-1180L1 parts guide keeps the model-specific references together.
Specify the complete clamp or the required half
List a complete assembly and an individual half as separate purchase items. If pins, bolts, nuts or springs are also required, identify them from the same assembly drawing and state their quantities. Avoid assuming that these items are included with an order for a single half.
The Pump Liner Clamp product page is a starting point for an inquiry. A photograph showing the installed clamp and its connection helps locate the requested item.
Prepare a short quotation request
- Pump model, nameplate photo and catalogue revision.
- Complete clamp assembly reference and figure position.
- Individual part numbers, or a clear request for a complete assembly.
- Available drawings or dimensions, photos, quantities and delivery destination.
Keep the two clamp groups separate in the purchase list so each requested component can be checked against its own assembly.
