Ask about your pump
Type a model, a printed part number, or a short description. The assistant searches this catalogue in your browser and shows matching records. That is not a promise of stock or interchange. An optional on-device language model can be started if you want a written summary of the same records.
This catalogue includes 91 pumps, 220 kits and 6009 parts from the public v75 catalogue (Kerr withheld). 45 already-public manuals are listed, minus withheld files. Lookup is not a guarantee of stock or interchange. The optional on-device model is off until you start it.
Questions
What does this assistant actually do?
It searches the published Dongli catalogue in your browser for a model, a printed number, or a short description, and shows the matching records. An optional on-device language model can summarise those same records after you choose to download it. Neither mode promises stock or interchange.
How many records are on this site?
This version includes 91 pump catalogue records, 220 kits and 6009 parts (6320 records from the public v75 catalogue, excluding 2005 withheld Kerr records), plus 45 manuals that v75 already listed publicly after Kerr, A-group and the withheld drawing are removed. 2 W-446 pump pages are marked PREP_ONLY (appearance study, pending technical review). Counts come from that rule, not an estimate.
Is the language model required?
No. Catalogue lookup works without it. The on-device model is click-to-start, about 276 MB, licensed Apache 2.0 (Qwen2.5-0.5B-Instruct via WebLLM), and runs only on this device. If your browser has no WebGPU, the site stays on catalogue lookup.
Does a match mean the part will fit or is in stock?
No. A catalogue match is a starting point. Send the nameplate, the printed number, and photographs to Dongli for a human check.
Why are some brands or manuals missing?
Kerr records and Kerr manuals, including KZ-3150PT, are withheld. So are the five A-group PDFs and drawing c322409dcab6. W-446 pump pages are marked as an appearance study pending technical review.
