Zigong Industrial Pump is a historic Sichuan hydraulic-engineering manufacturer (public founding 1967) for axial-flow, mixed-flow, slurry and multiphase service. Claimed plant area 270,000 m² and 500 staff remain supplier statements. The catalog is civil works and oilfield, not building CDL.
ZLB and HW live on the civil drawing. Blade angle and installation datum are the specification. Multiphase oil-gas-water pumps are project machines: gas volume fraction and viscosity are mandatory or the quote is fiction.
ZJ slurry at Zigong is a mining/metallurgical wear line. It is not the axial-flow flood pump in a different colour.

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; facility, staff and certification details require current-document 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.
Zigong HW mixed-flow pumps sit between axial-flow volume and centrifugal head for drainage projects.
Buyer note: Confirm installation datum and axial thrust.
Multiphase Series Multiphase process pump 5–400 m³/h 20–400 m API 610 / project specZigong markets multiphase pumps for oilfield oil-gas-water streams. These are project machines.
Buyer note: Gas volume fraction, viscosity and API data sheet are mandatory.
ZJ Slurry Series Heavy-duty slurry 10–2500 m³/h 10–80 m GB/T 13028Zigong ZJ slurry pumps cover mining and metallurgical abrasive service.
Buyer note: Specify liner and impeller alloy.
ZLB Axial-Flow Series Vertical axial-flow 300–20000 m³/h 2–12 m GB/T 13008Zigong ZLB vertical axial-flow pumps are a historic Sichuan hydraulic-engineering product for irrigation and flood control.
Buyer note: Civil drawing and blade angle are the specification, not the three letters.
What this record is not
- Three letters (ZLB, HW, ZJ) are not a pump without a civil or slurry data sheet.
- A multiphase brochure is not an API project specification.
- Irrigation axial-flow and mineral slurry do not share a wet end.
If you name this factory on an RFQ
- Attach civil drawings for axial- and mixed-flow.
- For slurry, specify liner and impeller alloy.
- For multiphase, give GVF, viscosity and the project spec.
- Ask for test and after-sales scope in writing; they are listed as capabilities, not as a free contract.

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.
