AI-Powered supplier vetting

SummaryShanghai Winning Electric Co., Ltd. is a China-based limited company focused on intelligent water-pump and motor-control products. The supplier describes capabilities in product design, R&D, system integration, automation implementation, and production, with applications in municipal water supply, drainage, industrial control, agricultural irrigation, and aquaculture. It reports eight production lines, export activity to Africa, Southeast Asia/Middle East, and Australia, and approximately one-month order fulfillment in both peak and off-peak periods. Evidence supports product specialization and some engineering capability, but certification details, after-sales resources, financial credibility, customization results, and specific customer cases remain insufficiently documented. The supplied data also contains inconsistencies, including differing establishment/manufacturer-start dates, employee and quality-control counts, and company-location information.

Supplier typeThe supplier is identified as a Chinese limited company and is described as both a manufacturer and R&D company specializing in motor and pump-control products. Its stated departments include production, technology, engineering, and business functions, indicating an integrated manufacturing and engineering profile.

R&D capabilityThe supplier states that it performs system design, research and development, product development, and integration for intelligent pump and motor-control products, and reports two years of total R&D-engineer experience. These statements support an innovation function, but the limited disclosed R&D experience and absence of patents, new-product records, or technical outcomes prevent a stronger assessment.

Production capacityThe supplier describes production capabilities and reports eight production lines, with products covering pump controllers, protectors, and related control equipment. It also states approximately one-month fulfillment in both peak and off-peak seasons, although the reported employee and quality-control figures are internally inconsistent and production capacity metrics are limited.

Customization capabilityThe supplier explicitly offers product design, development, system integration, and automation-project implementation, including intelligent controllers for pumps, air energy, geothermal, and boilers. This supports potential customization and engineering adaptation, but no specific customized project, technical specification, or delivery example is supplied.

Product Q&A

Q:How to convert HP to KW?

Use the formula 1HP = 0.74KW. For example, 3PH = 3 x 0.74KW/PH = 2.22KW.

Q:How to choose the right pump controller power?

Select a controller with higher power than the pump's rated power. For a 4KW pump, choose a 7.5KW controller. For deep well submersible pumps, please consult us first.

Q:Can I get samples for testing?

Yes, we can send pump controller samples for your testing purposes.

Q:Do you provide OEM or ODM services?

Yes, we can manufacture orders according to your detailed requests, supporting both OEM and ODM.

Q:What is the delivery time for orders?

Sample orders take 3-5 days. Regular orders for pump controllers take 15-20 days.
