AI-Powered supplier vetting

SummaryDong Guan Usun Fluid Control Equipment Co., Ltd. is identified as a Chinese trading company with five employees, while other records describe an established factory and five production lines. Its offering focuses on gas booster pumps, air-driven gas boosters, hydro-test pumps, high-pressure systems, and related components. The supplier reports export activity since 2013 and exports representing 90% of total sales, with markets across multiple regions. Peak- and off-season lead times are both stated as within 15 workdays. No management-system certifications are reported, and the quality-control team has fewer than five staff. The company description claims development of a pneumatic booster pump intended to replace a German product and worldwide customer acceptance, but no specific customer cases are provided. Evidence is insufficient to confirm after-sales service or customization capability.

Supplier typeThe supplier is explicitly classified as a trading company, including both the associated-company industry record and the business-entity type. This indicates the entity is primarily trade-oriented, although other records mention manufacturing activities and a factory history.

CertificationsThe supplier reports no certification of management systems (“NIL”). Therefore, the provided evidence does not show possession of management-system certifications.

R&D capabilityThe company description states that it developed a new type of pneumatic booster pump intended to replace a German product, and its listed products include gas booster pumps, high-pressure pump systems, and related components. This supports evidence of product-development activity, although the extent and verification of innovation are not provided.

Production capacityThe records identify five production lines, an 87.0 m² plant, fewer than five quality-control staff, and peak- and off-season lead times within 15 workdays. The supplier also describes a factory established in 2011, but its simultaneous classification as a trading company and limited operating scale indicate production capacity is evidenced but modest.

Product Q&A

Q:What gases can this booster pump handle?

It is suitable for Oxygen, CO2, Nitrogen, and most other gases. Other materials can be supplied for aggressive services.

Q:How is the outlet pressure controlled?

The outlet stall pressure is set by adjusting the air drive pressure via a simple air pressure regulator. It stops automatically when forces equalize.

Q:Does the pump require electrical power?

No, the air-driven models do not require electrical connections, making them safe and easy to apply with automatic controls.

Q:What is the recommended cycle rate for continuous operation?

We recommend a maximum cycle rate of 50-60 cycles per minute to increase service intervals and prevent ice formation at the exhaust.

Q:Is lubrication required for the air supply?

No, the seal system is designed for long working life and does not require airline lubrication.
