AI-Powered supplier vetting

SummaryThe supplier manufactures mechanical and hydraulic diaphragm metering pumps, plunger pumps, and screw pumps, with stated annual output exceeding 20,000 units. It reports over 10 years of R&D experience, new products in the past year, ODM services, SDK availability, OEM service for well-known brands, and customization from designs or samples. Production evidence includes three production lines, CNC and press equipment, and 100% finished-product inspection by four quality inspectors. The supplier holds ISO9001:2015 and CE certifications. Service controls include written supplier-assessment and corrective-action procedures, but complaint handling lacks written records. Overseas service infrastructure is limited, with no overseas warehouse, showroom, agent, or branch. Raw-material traceability and continuous production-quantity reconciliation are absent. Financial information is indicated for recent years, but the slices do not provide sufficient detail to assess financial credibility. Customer and...

Supplier typeThe supplier is presented as a manufacturer of mechanical and hydraulic diaphragm metering pumps, plunger pumps, and screw pumps. Its stated annual output exceeds 20,000 units, indicating an industrial equipment manufacturer rather than a service-only or trading entity.

CertificationsThe supplier reports an ISO9001:2015 certificate and CE capability, while its product description also states that operations are conducted under ISO9001 standards. These are explicit certification-related credentials supporting quality-system and product-compliance capability.

After-Sales capabilityThe supplier has written procedures and records for supplier assessment and corrective/preventive actions, and has participated in the Russian Water Exhibition. However, complaint handling has a procedure but no written records, and there are no overseas warehouses, showrooms, agents, or branches; overseas service coverage is therefore limited and documentation is incomplete.

R&D capabilityThe supplier reports more than 10 years of R&D experience, new products during the past year, ODM services, SDK availability, and one national science and technology progress award. These explicit indicators support established product-development and technical innovation capability.

Production capacityProduction evidence includes three production lines, CNC milling and press equipment, 100% finished-product inspection, four quality inspectors, and stated annual output above 20,000 units. Nevertheless, the factory does not continuously reconcile quantities for each batch or mass-production run, indicating a documented production-control weakness alongside substantial capacity.

Customization capabilityThe supplier explicitly provides customization from designs, customization from samples, and flexible customization. It also reports ODM service availability, directly supporting the ability to develop or modify products according to customer requirements.

Product Q&A

Q:Can your pumps handle corrosive fluids like acids or alkalis?

Yes. We provide pumps with wetted parts made of PVC\PVDF stainless steel, PTFE, or Hastelloy, designed to resist corrosion. Specify your fluid type when ordering to ensure compatibility.

Q:Do you provide installation guides for your metering pumps?

Absolutely. Each pump comes with a detailed installation manual (including diagrams). We also offer video tutorials on our website's 'Resources' page. For on-site support, inquire about our professional installation service.

Q:How do I adjust the flow rate of the pump?

Most models feature a manual adjustment knob (turn clockwise to increase flow, counterclockwise to decrease). Digital models can be programmed via the control panel or connected to external systems (e.g., PLC) for automated adjustment.

Q:What payment terms do you offer for bulk orders?

For orders of 5+ units, we accept T/T (30% deposit, 70% before shipment) or L/C at sight. Contact our sales team at sales to discuss terms.

Q:What is your warranty policy?

All pumps come with a 12-month warranty covering manufacturing defects. Wear parts (seals, valves) are covered for 3 months. Warranty does not apply to damage from improper use or lack of maintenance.
