Purity is a Wenling factory (founded 2010 in public sources) selling centrifugal, inline, sewage, fire and multistage pumps plus complete water-supply systems. The company profile states about 60,000 m² and 130+ countries. Those figures stay labelled as claims.
Indexed families reuse the most crowded Chinese letters: ISW, ISG, CDL, WQ, XBD. The only honest way to buy them is with Purity drawings. The letters are a filing system, not a standard product.
A testing center mentioned on a website is a capability tag until you have a named test report against a serial number.

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.
Official-site company claims; facilities and certifications have not been independently audited by KanBeng.
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.
Purity CDL stainless vertical multistage pumps compete in export booster packages.
Buyer note: Do not mix with CNP CDL hydraulics.
ISG Series Vertical inline centrifugal 5–1200 m³/h 8–80 m ISO 2858Purity ISG is the vertical in-line counterpart for plant-room boosting and circulation.
Buyer note: Confirm motor frame and seal plan on the Purity drawing.
ISW Series Horizontal inline centrifugal 5–1200 m³/h 8–80 m ISO 2858Purity ISW pipeline pumps are listed for HVAC and municipal water on the English company profile.
Buyer note: ISW is a Chinese generic. Use the Purity curve only.
WQ Series Submersible sewage 8–500 m³/h 6–40 m GB/T 24674Purity WQ sewage submersibles are catalogued alongside complete water-supply systems.
Buyer note: Specify solids, cable and rail system.

Buyer note: Validate fire listing for the exact driver and controller combination.
What this record is not
- ISW/ISG here are not ISO 2858 twins of Kaiquan or Pacific pipeline pumps.
- Purity CDL is not CNP CDL.
- A complete water-supply system quote still needs a pump curve, a tank drawing and a controller listing as separate documents.
If you name this factory on an RFQ
- Insist on Purity curve numbers on every booster and inline line.
- For XBD, validate listing for pump, driver and controller together.
- For CDL, state chloride and stage count.
- Ask whether the test center will issue a report for the serials you buy.

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.
