This indicates a manufacturer and integrated industrial-equipment service provider rather than a sales-only trading entity.

CertificationsThe supplier reports CE product compliance certification and ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. These stated certifications provide explicit evidence of compliance and management-system coverage.

After-Sales capabilityThe supplier reports overseas debugging, maintenance, repair, training, and equipment installation, supported by an overseas warehouse and showroom. It also states that service-capability procedures, corrective and preventive actions, and customer-complaint handling have written procedures and followed records, indicating a documented service-management framework.

R&D capabilityThe supplier states that it had new products during the past year, provides ODM services, and has an available SDK. It also reports R&D capability for intelligent robots and multiple forms of design customization, providing explicit evidence of product-development and technical-development capability.

Production capacityThe supplier lists assembly, CNC lathes, a CNC planomiller, drilling and milling equipment, a five-axis machining center, welding, painting, balancing, CMM, spectrometry, hardness testing, and test-room resources. It also reports manufacturing activities, inventory capability, and valid contracts with each associated subcontractor, supporting a substantial production and capacity-management capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These options are stated in both the R&D and design-capability information, demonstrating broad customization coverage.

Client casesThe supplier reports providing OEM services for well-known brands and having collaborated with Fortune 500 companies. It also reports a repeat-buyer preference range of 50%–80%, but the slices do not identify the customers or provide project details, performance results, or references.

Product Q&A

Q:What is the maximum vacuum degree achievable?

The pump can achieve a suction pressure of 33mbar(A), which corresponds to a vacuum degree of 97%.

Q:Is the pump suitable for flammable and explosive gases?

Yes, the isothermal compression process during operation makes the pump not easy to explode, ensuring safety with flammable and explosive gases.

Q:What protection is needed for low suction pressure?

When working under suction pressure lower than 80mbar long term, the pump should be protected by connecting cavitation protection piping.

Q:Can the pump be used as a compressor?

Yes, if equipped with an atmospheric ejector installed on the inlet, it can be used as a compressor with a maximum available pressure of 0.26Mpa(A).

Q:What materials are used for the impeller and wet parts?

The impeller is made of ductile iron for high strength. Wet parts can use stainless steel material to improve corrosion resistance in serious environments.
