CNP / Nanfang is the Hangzhou stainless-multistage name most export buyers already know. The indexed families—CDL, CDLF, CHL, NISO and TD—are the ones that actually show up in booster, RO and HVAC packages.
The legal-entity and facility story is still open on this record. The English product site is a catalog, not a corporate filing. Do not treat “CNP” as a single factory you have already audited.
CDL versus CDLF is the most expensive mix-up in this index. Same architecture, different material schedule. Mixing CNP curves with another Chinese CDL table is how booster packages fail in the field.

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 contact source captured from the company website; legal entity and facilities require review.
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.
CNP CDL is Nanfang’s flagship stainless vertical multistage pump, widely specified for boosting, RO and washing systems.
Buyer note: Stage count, motor IE class and chloride concentration control the selection. CDL and CDLF are not the same material schedule.
CDLF Series Stainless vertical multistage 0.4–180 m³/h 12–305 m ISO 9906CNP CDLF is the all-stainless (or 316L) variant of the CDL architecture for slightly more aggressive water.
Buyer note: Do not substitute CDL hydraulics for CDLF materials. Confirm elastomer, shaft and impeller alloy on the CNP BOM.
CHL Series Horizontal multistage 0.4–28 m³/h 12–250 m ISO 9906CNP CHL is a compact horizontal multistage booster used where headroom for a vertical stack is limited.
Buyer note: Confirm NPSH and minimum flow. Horizontal multistage machines are sensitive to suction air.
NISO Series End-suction centrifugal 4–1500 m³/h 8–150 m ISO 2858CNP NISO is an ISO 2858 end-suction centrifugal line for water, HVAC and light process.
Buyer note: ISO 2858 dimensions do not freeze hydraulics. Require the CNP NISO curve for the offered impeller diameter.
TD Series Inline circulation 2–1200 m³/h 4–40 m ISO 9906CNP TD inline circulators are sold for HVAC secondary loops and district heating branches.
Buyer note: Confirm fluid temperature, glycol percentage and speed control. TD is a crowded series name—use the CNP model index, not a generic TD table.
What this record is not
- A CDL booster skid photo is not a chloride-safe CDLF selection.
- NISO being ISO 2858 does not make it interchangeable with Kaiquan or East Pump end-suction pumps.
- TD is a crowded series name; a generic TD booklet is not the CNP model index.
If you name this factory on an RFQ
- State CDL or CDLF explicitly, with stage count and motor IE class.
- Give chloride, temperature and minimum-flow protection for stainless stacks.
- For NISO, send the required impeller diameter, not only the series.
- For TD, specify fluid, glycol percentage and whether speed control 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.
