AI-Powered supplier vetting

SummaryDepamu (Hangzhou) Pumps Technology Co., Ltd. is a China-based limited-company factory established in 2003, with 352 employees and operations in Hangzhou, Zhejiang. Its listed products include pressure safety valves, back pressure valves, and double diaphragm pumps. The supplier reports ISO 9001:2015 and other management-system certifications, API 675-aligned products, and certifications from authorities including DNV and ISO 9001:2000. It has 24 years of total R&D-engineer experience, exports to Southeast Asia and the Middle East, and has reportedly served 12 countries and regions. A TUV Rheinland audit record is provided for September 2, 2024 through September 1, 2025, but the audit result is recorded as 0 without interpretation. Many operational, service, customization, quality-control, sustainability, and R&D details remain marked unknown, so several fields cannot be conclusively assessed.

Supplier typeThe supplier is identified as a factory and a limited company, operating in manufacturing-related industries in Hangzhou, Zhejiang, China. Its company type is also recorded as “Combined,” but the available information supports classification as a manufacturing supplier.

CertificationsThe supplier reports ISO 9001:2015 and other management-system certifications, while its product description references API 675 compliance and certifications from DNV and ISO 9001:2000. A TUV Rheinland audit is documented for September 2, 2024 to September 1, 2025, although the audit evaluation result is recorded as 0 and is not explained.

R&D capabilityThe supplier reports 24 years of total R&D-engineer experience and describes technology introduced from Germany, including hydraulic diaphragm metering pumps and mixed-type dosing devices. However, product-information R&D, ODM, SDK, private-mold, professional-technique, 3D-design, and R&D-documentation capabilities are marked unknown, limiting assessment of current innovation breadth.

Production capacityThe supplier is identified as a factory with 352 employees, offers multiple pump and valve products, reports a one-month off-peak lead time, and states that its products are exported to 12 countries and regions. Outsourcing procedures, manufacturing-capacity contracts, inventory capacity, and the meaning of the order-fulfillment value are not explained, so production scale and fulfillment reliability cannot be fully verified.

Client casesThe supplier reports exports to Southeast Asia and the Middle East and states that its products have been exported to 12 countries and regions, including France, Australia, South Africa, and Southeast Asia. These statements demonstrate international market exposure, but no named customers, project references, order examples, or independently verified case studies are provided.
