DongliField guide / HDD mud pumps
From a part number to a reliable inquiry.
Only have a printed part number? Copy it exactly, identify the pump and its configuration, compare the number with the relevant manual table, then send the evidence for a human check. A search match alone does not confirm fitment.
Identification sequence
Four checks before you ask for a replacement.
These steps help our team identify the reference you mean. They do not turn a similar number or picture into a confirmed interchangeable part.
- 01 / Pump
Keep the complete pump identity.
Record the brand, full model, suffix and nameplate or serial marking if visible. Note the actual configuration. If any field is unknown, leave it unknown rather than guessing from a nearby model.
- 02 / Marking
Copy the old part number as printed.
Preserve letters, leading zeros, hyphens and suffixes. Photograph the marking before cleaning or discarding the old part. A fuzzy search suggestion can help locate a record; a spelling variant is not proof of interchangeability.
- 03 / Source
Trace the number to a manual table.
Use the catalog and parts-manual library to record the document title, edition if shown, table heading, printed number and physical PDF page. A text hit proves only that the number appears there; some manuals cannot jump to an exact page automatically.

Send the evidence for a human check.
Share the pump identity, original number, source page, clear photos, quantity and any dimensions or duty details you know. Dongli can then discuss the requested reference and what remains to be verified; this page does not promise fitment, stock, price or lead time.

A match can show
A traceable reference.
- The entered number or a clearly labeled near match.
- A document and page link where an exact, reviewed manual lookup is available.
A match cannot prove
Fitment or supply.
- That two similar numbers or model suffixes are interchangeable.
- Dimensions, material, stock, price or delivery for your machine.
When the sources disagree
Do not choose by the model label alone.
A catalog grouping, manual table and old-part marking may describe different configurations. Keep each source and its page separate, and ask for an equipment-specific check before treating a candidate as a replacement.
