Neptune (Changsha) presents vertical turbine, split-case, fire, cryogenic and emergency-drainage products. The catalog is wider than a municipal water OEM and narrower than a full API house. Cryogenic machines on a brochure are engineered products; they are not stock CDL boosters with a low-temperature sticker.
Identity and product scope are still marked for source review. That is not a slight. It is the honest label: the website is broad, the file behind this record is not yet thick.
Emergency-drainage and cryogenic should never share an RFQ. They do not share metallurgy, testing or commercial lead time.

How to read this plant
Figures in the ledger are supplier or public-site claims until a document is on file. Capabilities are routing tags. The evidence label is the only statement KanBeng makes about how far review has gone.
- City and founding year identify the record; they are not quality scores.
- Plant area and headcount stay labelled as claims.
- Series letters are crowded across Chinese catalogs—use this factory’s drawing, not a generic booklet.
- A listing is not an endorsement, a factory audit or a product certificate.
Identity and product scope require completion of KanBeng source review before any verification label.
Indexed series
These are published catalog families KanBeng could attach to this manufacturer. Ranges are envelopes, not a promise that one frame covers the whole band. Open the model record for materials, installation and selection notes.

What this record is not
- A cryogenic family name is not an API data sheet.
- A flood-control envelope is not a split-case circulating duty.
- A fire photo is not a certificate.

- For cryogenic, require material certificates, cooldown procedure and a completed data sheet.
- For turbines, send civil setting and submergence.
- For emergency drainage, confirm solids, submergence and whether a transport skid is in scope.

Questions buyers actually ask
Is this factory verified?
Read the evidence label on this page. Source pending means we captured a public identity and catalog families. It is not a site audit, a process-capability study or a product certificate.
Can I order from the envelopes on this page?
No. Envelopes are index ranges from public catalogs. The controlling document is the manufacturer-issued curve, material schedule and test grade for the serial you buy.
Why do so many factories share series letters?
Chinese pump designations are crowded. The factory name plus the drawing number is the product. The three letters are a filing cabinet.
How do I put this plant on an RFQ?
Use Send a requirement and name the factory. Incomplete duty points are not forwarded as if they were specifications.
