AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier focused on pumps, environmental applications, and related equipment. It provides 3D design, OEM, ODM, and multiple customization options, and reports new-product development during the past year. ISO 9001 certification, defined complaint-handling procedures with records, and 11–20 quality-control staff support its quality-management profile. Production information includes inverter solar pump controllers, submersible and water pumps, solar pumps, solar systems, and stainless-steel pumps. Export sales represent 90% of total sales, with five years of export experience and self-operated import/export rights. However, the supplier has no overseas agents or branches, overseas warehouse, showroom, inventory capability, or available SDK. Financial information is limited to years identified in the records and does not provide sufficient evidence for a credibility assessment.
Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and describes experience in pumps and environmental applications. Its listed business scope includes pumps, valves, gas-compression machinery, generators, photovoltaic equipment, and other industrial equipment, indicating a technical equipment supplier rather than a general trading-only profile.
