AI-Powered supplier vetting

SummaryHEFEI CHANGYUAN HYDRAULIC CO., LTD. is a China-based manufacturer of hydraulic pumps and motors, valves, and cylinders. The supplier reports more than 10 production lines, annual capacities of 400,000 hydraulic gear pumps or motors, 400,000 hydraulic valves, and 200,000 hydraulic cylinders, supported by 81 years of combined R&D engineer experience and 31–40 quality-control staff. It holds ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates. The company exports under self-operated import and export rights to South America, Southeast Asia/Mideast, Europe, and Australia, with stated lead times of one month off-peak and two to three months during peak periods. Evidence is insufficient to assess after-sales service, customization capability, or financial credibility without using monetary information. One recorded transaction and an associated buyer are identified, but broader customer-case evidence is limited.

Supplier typeThe supplier is explicitly identified as a manufacturer and specializes in the R&D, production, and sales of hydraulic pumps, motors, valves, and cylinders. Its stated commercial categories and product keywords are consistent with industrial hydraulic equipment manufacturing.

CertificationsThe supplier reports holding ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates, covering quality, environmental, and occupational health and safety management systems. These are explicit certifications relevant to manufacturing-system management.

R&D capabilityThe company describes itself as a high-tech enterprise specializing in R&D, production, and sales, and reports 81 years of total experience among R&D engineers. These points support an established R&D capability, although no patents, new-product records, or specific innovation outcomes are provided.

Production capacityThe supplier reports 645 employees, more than 10 production lines, a 93,300 m² manufacturing plant, and annual capacities of 400,000 hydraulic gear pumps or motors, 400,000 hydraulic valves, and 200,000 hydraulic cylinders. It also states one-month off-peak lead times and two-to-three-month peak-season fulfillment times, providing direct evidence of substantial production capacity and defined delivery schedules.

Client casesThe supplier states that it has been awarded excellent supplier status for many years, and one trade record identifies HYDRAULINK ENTERPRISES as an associated buyer for a hydraulic gear pump transaction. The evidence demonstrates at least one identifiable buyer relationship, but does not establish a broad portfolio of verified customer cases.
