AI-Powered supplier vetting

SummaryThe supplier is a China-based hydraulic components agent and distributor with over ten years of experience representing Rexroth and Sauer-Danfoss products, and it also provides hydraulic system design, production, maintenance, and technical services. It reports TS 16949 and ISO 9001 certifications, export experience of eight years, and export sales accounting for 51%–70% of total sales. Customization is available, but only as flexible or minor customization. Innovation evidence is limited: there was no new product in the past year, no ODM, no SDK, no 3D design service, and only one R&D engineer. Service-management controls are weak or undocumented, with no written procedures for complaint handling, corrective actions, or service-capability assessment. Overseas service infrastructure is absent, although the supplier has attended PTC ASIA and accepts multiple trade and payment terms. Quality assurance and traceability status are unknown, and reported quality-control testing equipment is zero. No specific...

Supplier typeThe supplier describes itself as an agent and distributor of Rexroth and Sauer-Danfoss hydraulic control components, while also offering system design, production, maintenance, technical services, and flexible or minor customization. It exports through agents and under its own import/export rights, with eight years of export experience.

CertificationsThe supplier reports holding TS 16949 and ISO 9001 supplier-management-system certifications. These are explicit certification claims, although the provided information does not include certificate numbers, validity dates, or scope.

After-Sales capabilityThe supplier states that it provides maintenance and professional technical services and reports lead times within 15 working days in both peak and off-season periods. However, it has no written complaint-handling, corrective-action, or service-capability assessment procedures, no overseas agents or branches, no overseas showroom, and serves zero countries overseas; therefore, formal and international after-sales support is not demonstrated.

R&D capabilityInnovation capability appears limited: the supplier has one R&D engineer, no available SDK, no 3D software design service, no ODM service, no professional-technology-supplier designation, and no new product reported in the past year. Its R&D engineer is assigned to developing new supply chains based on customer needs, but this does not establish strong product innovation.

Customization capabilityThe supplier explicitly offers flexible customization and minor customization for design services. It does not offer ODM, popular-brand OEM, or 3D software design services, so customization is available but appears limited in scope.

Product Q&A

Q:How do displacement and RPM correspond across A4VG models?

Higher displacement results in higher flow rates but lower maximum operating speeds. For example, A4VG28 reaches 4250 rpm, while A4VG250 reaches 2400 rpm. Choose based on the host machine's required flow rate.

Q:What are the differences between EP, HD, HW, and EZ controls?

EP offers continuous stepless flow for precision; HD is hydraulic remote control for harsh environments; HW is mechanical-hydraulic servo for fast response; EZ is two-stage switching for simple, low-cost applications.

Q:What are the rated and peak pressure ratings?

All A4VG models have a rated pressure of 400 bar and a peak pressure of 450 bar. They can withstand short-term surges up to 500 bar.

Q:Can I replace the pump in my machine directly?

Yes, the series features a 32-series universal interface compatible with most host systems, designed for high-pressure closed-circuit hydraulic systems.

Q:How can I contact customer service for support?

We provide 24-hour technical support including remote guidance for installation, commissioning, and troubleshooting. Free repair or replacement is available for non-human-caused damage within the warranty period.
