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 is the warranty period for this pump?

We provide a 1-year warranty for this portable pneumatic hydrostatic testing pump unit.

Q:What is the maximum operating pressure?

The maximum outlet pressure is achieved at an air driven pressure of 8 bar (116 PSI). For long life, we suggest not exceeding 8 Bar.

Q:What power source does the pump use?

The pump is pneumatic, driven by compressed air within the range of 3-8 Bar.

Q:Is the pump suitable for continuous operation?

Yes, but for continuous basis operation, we recommend a maximum cycle rate of 50-60 cycles per minute to prevent icing and increase service intervals.

Q:What materials are used for the wetted parts?

Wetted materials include carbon steel or stainless steel, depending on the specific model and application requirements.
