AI-Powered supplier vetting

SummaryJiangxi Dongling Technology Co., Ltd. is identified as a China-based trading company operating in Jiangxi, with factory information separately provided for a location in Pingxiang, Jiangxi. Its product scope covers laboratory analytical instruments and engineering monitoring and structural safety systems. The supplier reports ISO 9001 certification, 4 production lines, 31–40 years of combined R&D engineer experience, and 6–10 quality-control staff. Reported annual productivity is 350 sets of laboratory analytical instruments and 800 sets of engineering monitoring equipment. It exports to multiple regions, with 31%–40% of sales from exports and exporting activity beginning in 2020. The available information supports production, quality-system, product-scope, and international-market capabilities, but does not provide sufficient evidence regarding after-sales performance, customization, customer cases, or overall financial credibility.

Supplier typeThe supplier is explicitly classified as a trading company, while the records also identify a factory location in Pingxiang and report production lines and output. Its stated business model covers two capability lines: laboratory analytical instruments and engineering monitoring and structural safety systems.

CertificationsThe supplier reports holding ISO 9001 certification for its management system. This is explicit evidence of a certified quality-management framework, although the provided information does not specify the certification scope or validity period.

R&D capabilityThe supplier reports 31–40 years of total R&D engineer experience and describes two technical capability lines spanning analytical instruments, engineering monitoring, and structural safety systems. This supports an established technical base, but there is no specific evidence of patents, new product development, or documented innovation outcomes.

Production capacityThe supplier reports 4 production lines and annual productivity of 350 sets of laboratory analytical instruments plus 800 sets of engineering monitoring equipment. These stated production resources and output figures provide explicit evidence of operating production capability across both product categories.

Product Q&A

Q:What is the maximum working pressure?

The maximum working pressure is 42.0 MPa. It features upper and lower limit settings with an automatic alarm function.

Q:How does the pump ensure low pressure pulsation?

It uses a patented 'floating pump plunger rod sealing ring' technology and a reciprocating dual-plunger rod series pump head, achieving pressure pulsation of less than 10Psi (or < 0.1 MPa) in the specified flow range.

Q:Can the pump be controlled externally?

Yes, it features an RS-485 external communication interface, allowing control by a workstation which can display various parameters in real-time.

Q:What are the key automatic functions of the pump?

The pump features automatic venting and automatic cleaning functions, which effectively extend the service life of the plunger rods and sealing rings.

Q:What is the warranty period and after-sales service?

The warranty period is 1 year. After-sales service includes remote teaching and timely communication to solve problems, with technical support provided within 24 hours.
