Deep Blue is a Dalian fluid-machinery group (public founding 1988) aimed at petrochemical, coal-chemical, cryogenic and industrial rotating equipment. The indexed families are API-style BB2, BB3, VS6 and cryogenic process pumps. This is a different buyer universe from Wenling CDL.
The site states a large plant, 40+ countries, precision casting and aftermarket service. None of those figures have been independently audited here. The technical rule is simple: buy from a completed API 610 data sheet, not from a website family name.
VS6 can length, first critical speed and NPSH3 are project numbers. BB3 balance devices and nozzle loads are project numbers. If the inquiry does not contain them, it is not an inquiry.

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; asset, facility and export figures 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.
Deep Blue presents API-style BB2 between-bearings process pumps for petrochemical and coal-chemical service.
Buyer note: Require a completed API 610 data sheet, not a website family name.
BB3 Multistage Series Axially split multistage 10–800 m³/h 80–1200 m API 610 BB3Deep Blue BB3-class axially split multistage pumps are pipeline and process high-head machines.
Buyer note: Balance device, nozzle loads and API test grade must be specified.
Cryogenic Series Cryogenic process pump 5–600 m³/h 20–500 m API 610 cryogenic optionDeep Blue cryogenic pumps are marketed for LNG and related low-temperature services.
Buyer note: Cooldown, materials and seal system are engineered—do not buy from an envelope table.
VS6 Vertical Can Vertical canned process 8–1500 m³/h 20–400 m API 610 VS6Deep Blue VS6 vertical can pumps address low-NPSH hydrocarbon and chemical suction conditions.
Buyer note: Can length, first-critical speed and NPSH3 are project-specific.
What this record is not
- A BB2/BB3/VS6 label on a homepage is not an API-monogrammed machine.
- Cryogenic service is not “stainless CDL, colder”.
- Export to 40+ countries is not a local spare-parts commitment.
If you name this factory on an RFQ
- Attach a completed API 610 data sheet, not a one-line duty.
- State nozzle loads, test grade and documentation package.
- For VS6, give can length and NPSH available.
- For cryogenic, write cooldown, materials and seal system as engineered items.
Stated capabilities and papers
The tags below are copied from public company copy. They are useful for routing and useless as a substitute for a named certificate, a test report or a process-capability file.
- Mechanical research and development
- Precision casting
- Pump manufacturing
- Rotating-equipment service
No certificate numbers are indexed on this record. A mark on a homepage is not a listing.
Export markets stated: 40+ countries and regions stated. Geography on a website is not proof of local service.
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.
