Quick Answer: China has a deep centrifuge industry, from state-linked research institutes such as Shanghai Centrifuge Institute and Chongqing Jiangbei Machinery to private specialists such as Huada, Huading, Hanpu, Shenzhou, ZK Separation, and GN Solids Control. They differ more by application focus than by headline specs: some lead in municipal sludge, some in oilfield solids control, some in food and oil processing. Judge each on references, test results, certifications, and service rather than on country of origin.
How this list was built
There is no independently audited ranking of Chinese decanter makers by sales, so this is not a ranked list. The companies are shown alphabetically. They were selected because they are named in market research reports as significant producers, have a long operating history, or have a visible export presence and a clearly stated decanter product line. Descriptions rely on each company's own public information, which we have not independently audited.
Disclosure: this article is published by Jinhua Shenzhou Centrifuge Co., Ltd., which appears on the list. We have described every company, including ourselves, in the same plain terms. Two entries (Nanjing Zhongchuan and Wuxi Zhongda) are included because they are repeatedly named in market research, but we could verify only limited public detail on them, and we say so. Please confirm all details directly with each manufacturer before you buy.

Fits when: Your process needs both decanters and high-speed disc separators for oil or food clarification.
6. Nanjing Zhongchuan
Best known for: Named in several global decanter market reports as a notable Chinese producer.
Note: We could verify only limited public detail on this company. If it is on your shortlist, request a company profile, references, and test data directly.
7. Shanghai Centrifuge Institute (SCI)
Founded: 1958 (originally the "651 Institute"); part of Shanghai Electric Group
Best known for: Horizontal decanter centrifuges for municipal and industrial sludge, river and lake dredging, and mineral dewatering. The company states it has 11 LW series from LW220 to LW1100 with over 200 models, began technical cooperation with Germany's KHD Humboldt in 1995, and also offers Centridry sludge-drying systems.
Fits when: You need large-capacity sludge dewatering and a supplier with research-institute heritage and ISO 9001 certification.
8. Shenzhou
Company: Jinhua Shenzhou Centrifuge Co., Ltd., Zhejiang, founded 1980
Best known for: Horizontal decanter centrifuges in 2-phase and 3-phase configurations, disc separators, and sludge dewatering systems, including truck-mounted mobile units. The company states that it holds ISO 9001 and CE certification and supplies customers in more than 70 countries.
Fits when: You are comparing quotes and want a cost-competitive option with a broad decanter range and custom configuration, and you are prepared to verify references and spare-parts support.
9. Wuxi Zhongda Centrifugal Machinery
Best known for: Named in global decanter market reports as a notable Chinese producer.
Note: As with Nanjing Zhongchuan, we could verify only limited public detail. Request a profile, references, and test data directly before shortlisting.
10. ZK Separation
Best known for: 2-phase and 3-phase decanters, screen-bowl decanters, and disc-stack separators, with an "intelligent O&M" service offering. Published projects include oilfield drilling waste and palm oil extraction, for example a 3-phase LWS450 unit rated at 3,500 rpm and about 3,087 G delivered to a Russian customer.
Fits when: You need 3-phase machines for oily sludge or palm oil and want a supplier with published project parameters and multilingual support.

How to Vet a Chinese Decanter Centrifuge Supplier
- Confirm it is a manufacturer. Many online listings mix factories and trading companies. Ask for factory photos, an on-site or video audit, and the legal entity that holds the manufacturing license.
- Ask for references in your industry and region. Request contacts you can call, not only photos.
- Test on your material. Insist on bench or pilot tests and compare measured cake dryness, clarity, and capture rate to the quoted values.
- Check certifications. ISO 9001 and CE are useful quality signals, but confirm what applies to your market, including electrical codes and, for hazardous areas, ATEX or equivalent.
- Inspect materials and wear protection. Ask for material certificates for the bowl and conveyor and for the wear-protection specification.
- Plan for service. Confirm spare-parts stocking, lead times, commissioning support, and remote diagnostics.
- Compare total cost. Include freight, duties, installation, polymer or chemical use, power, and wear parts, not just the equipment price.
- Get warranty terms in writing, tied to measured performance.
FAQ
Are Chinese decanter centrifuges good quality?
Quality varies by manufacturer, as it does anywhere. Established makers with long histories, relevant certifications, and verifiable references can deliver reliable machines. Judge each supplier on evidence.
Which Chinese decanter manufacturers are best for sludge dewatering?
SCI, Chongqing Jiangbei, Huada, and Shenzhou all state strong municipal and industrial sludge experience. Test on your sludge before deciding.
Which are best for oilfield and drilling applications?
GN Solids Control and ZK Separation both publish oilfield and drilling-waste projects.
Are Chinese decanter centrifuges cheaper?
They are often priced below established Western OEMs, but compare total cost of ownership, including service, parts availability, and energy and polymer use.
How do I avoid trading companies posing as factories?
Ask for the manufacturing license, factory photos, and a live video audit, and check who will provide warranty service.
What do I need to request a quotation?
Feed type, solids concentration, flow rate, particle characteristics, target cake dryness, materials requirements, and any explosion-proof or hygiene requirements.
Send us your feed data and we will prepare a sizing recommendation and budgetary quote you can benchmark against other suppliers.
