AI-Powered supplier vetting

SummaryJinan Runway Automation Co., Ltd. is identified as a China-based trading company and manufacturer/factory in Jinan, Shandong, with products focused on pumps, valves, fluid-control systems, and related components. The supplier reports ISO 9001 certification, more than 10 production lines, 21–30 quality-control staff, 6–10 years of R&D engineer experience, and stated annual capacities of 50,000 valves and 10,000 gear pumps. It has exported since 2019, serves several international regions, and reports one-month off-peak and two-to-three-month peak lead times. The information supports production, quality-management, export, and customization capabilities, while after-sales service, financial credibility, and customer-case evidence remain insufficiently documented.

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory. Its materials describe manufacturing and R&D of transmission-control components, while another slice identifies it as the foreign-trade sales company of Shandong Shijing Machinery; the legal-name information is therefore not fully consistent across the supplied records.

CertificationsThe supplier explicitly reports holding ISO 9001 certification for its management systems. No certification scope, certificate number, issuing body, or validity period is provided.

R&D capabilityThe supplier reports 6–10 years of R&D engineer experience, a design and R&D team, advanced production and testing equipment, and a focus on producing and developing transmission-control components. These statements provide explicit support for R&D capability, although no patents, proprietary technologies, or quantified R&D investment are supplied.

Production capacityThe supplier reports more than 10 production lines, 21–30 quality-control staff, and annual capacities of 50,000 valves and 10,000 gear pumps. It also states lead times of one month in off-peak periods and two to three months in peak periods, supporting an established production operation.

Customization capabilityThe supplier explicitly offers customized processing services and states that its technical and sales teams provide feasible fluid-control solutions. This directly supports customization capability for its pumps, valves, fluid-system accessories, and related components.

Product Q&A

Q:How to adjust the back pressure valve?

1) Never exceed the maximum working pressure of the metering pump. 2) When there is pressure at the suction end of the metering pump, the pressure at the discharge end of the pump should be at least 1 bar higher than the pressure at the suction end.

Q:How to set the pressure of the safety valve?

The pressure of the safety valve can be adjusted within the rated working pressure range of the metering pump, and it is not allowed to exceed the maximum working pressure of the metering pump. Generally, the set pressure of the safety valve is 1-2 bar higher than that of the back pressure valve.

Q:What is the adjustable pressure range for the safety valve?

The safety valve pressure can be adjusted on-site within 0-1.0 MPa using the screw and pressure gauge.

Q:What is the adjustable pressure range for the back pressure valve?

The back pressure valve can be adjusted on-site within 0-0.6 MPa using the screw and gauge.

Q:What materials are available for the filter?

Filter materials include UPVC, PP, CPVC, and PVDF.
