When a fluid-end part fails, the first need is a confirmed identification, not a marketing claim. This article explains how to use the Dongli catalogue to review aftermarket records associated with NOV, Gardner Denver and Bomco mud pumps. Brand names identify reference equipment only. A listing is not original-equipment manufacture, interchange approval, or a stock commitment.
Risks when sourcing aftermarket parts
Original-equipment channels can have long lead times. Aftermarket catalogues exist to help identify replacement options, but a close part number or a similar model name can still be wrong for a given edition. Using an unconfirmed part can cause a poor fit or a further failure. The safeguard is to compare the nameplate, the printed number and the manual before you order.
What to check on a catalogue page
- The pump model and any suffix or pressure marking on the nameplate.
- The part number as printed on the old part, not only the heading on a web page.
- Material or size wording when those fields are present on the record.
- The original manual edition or page, when you have it.
The English-language catalogue currently lists 472 pump records, including models associated with NOV, Gardner Denver and Bomco. That figure is a catalogue count, not proof that a given part is in stock or that every variant is covered.
Brand entry points on this site
These pump-brand hubs stay inside donglipumps.com:
- [NOV pumps](/en/pumps/brand/nov/)
- [Gardner Denver pumps](/en/pumps/brand/gardner-denver/)
- [Bomco pumps](/en/pumps/brand/bomco/)
Part records for these pumps are reached from the pump page or from the [parts catalogue](/en/parts/), not from a separate NOV, Gardner Denver or Bomco parts-brand hub (those hubs are not in the current catalogue).
If a brand hub is empty or a model is missing, do not infer coverage. Use [find parts](/en/find-parts/) or contact the team with the identifiers above.
FAQ
How does Dongli confirm a part for a NOV, Gardner Denver or Bomco pump?
Dongli reviews the identifiers you send against the catalogue record and the original documents for that enquiry. The catalogue of 472 pump records is a starting point for that review. It does not, by itself, confirm fitment, interchange or availability.
What fluid-end parts are listed?
The catalogue includes liners, pistons, valves and seats, and other fluid-end records when those entries exist for a model. Open the pump or part page to see which records are actually listed. Do not assume a "full range" is in stock.
What if my pump is an older or uncommon variant?
Search by the nameplate wording and the printed part number. If no record matches, send those identifiers and a photo of the old part. A nearby model in the catalogue is not a substitute confirmation.
