AI-Powered supplier vetting
SummaryThe supplier is identified as a professional technical supplier with 3D software design, customization, ODM, SDK, and recent new-product development capabilities. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications, and has documented procedures for corrective actions and customer complaints. However, evidence indicates limited operational scale: one production line, one quality inspector, one year of export experience, no inventory, no overseas warehouse, no overseas agents or branches, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial results include a stated operating loss, but monetary figures are omitted here. Customer cases and named reference customers are not provided.
Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope covers mechanical and electrical equipment, industrial control systems, electrical instruments, electronic products, chemical products subject to applicable exclusions, solid waste treatment, and rolling processing.
CertificationsThe supplier reports holding ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These stated certifications provide explicit evidence of quality, occupational health and safety, and environmental management certification.
After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, supporting structured service handling. However, it reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches, and no participation in offline trade shows, indicating limited overseas service infrastructure.
Financial creditFinancial information is reported for the last two years, but the latest stated operating profit is negative. This is explicit evidence of profitability weakness, while the available slices do not establish broader financial stability or creditworthiness.
R&D capabilityThe supplier reports 3D software design services, SDK availability, ODM services, and new products developed during the past year. These capabilities explicitly support product development and technical innovation, although the supplier does not provide OEM services for popular brands.
Production capacityThe supplier reports one production line and one quality assurance or quality control inspector, with finished products checked by packing staff. It also lacks inventory capacity and has no valid manufacturing-capacity contract with affiliated subcontractors, indicating limited and potentially less resilient production capacity.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same range is reported in both technical design and design-services information, providing strong evidence of broad customization coverage.
Product Q&A
Q:Which brands of screw pumps are your spare parts compatible with?
A:
Perfectly compatible with mainstream screw pump brands at home and abroad such as Netzsch, Seepex and Mono. All models are precisely matched without equipment modification.
Q:Are the spare parts in OEM standard size? Will there be jamming after installation?
A:
Processed strictly in accordance with OEM drawings and tolerance standards by CNC with accurate size and high fitting degree. Smooth installation without pump jamming.
Q:What are the common materials for rotors and stators? How to select the right one?
A:
Rotor materials include 304/316 stainless steel and duplex steel; stator materials include NBR, EPDM and HNBR rubber. Select according to the pH value, temperature and wear strength of the conveying medium.
Q:Can the spare parts resist sewage, slurry and chemical corrosive media?
A:
Yes. Anti-corrosion and wear-resistant materials combined with hardening technology are suitable for long-term conveying of sewage, sludge, acid-base chemical slurry and other complex media.
Q:What causes leakage after replacing new stators and rotors?
A:
Mostly caused by improper assembly gap, mismatched model or worn old pump body. It can be solved by confirming model matching and standard installation. We provide professional technical guidance for difficult problems.
