Sourcing Coupling from Dongfang Yoyik Engnieering Co., Ltd. - China Import Guide
Before placing an order, verify the coupling model's compatibility with your existing turbine or pump systems, as the LK4-32-1010 is designed for specific configurations. Confirm the bore size, keyway dimensions, and torque capacity to ensure seamless integration. Request detailed technical drawings and material certificates to validate the product specifications.
Discuss logistics details with Dongfang Yoyik Engnieering Co., Ltd., including lead times, which may vary based on order volume and customization requirements. Clarify Incoterms such as FOB or CIF and agree on payment terms, typically involving a deposit followed by balance payment upon inspection or before shipment. Port of loading in China should be confirmed, as Sichuan’s inland location may affect transit routes.
Inspect the coupling upon arrival for dimensional accuracy, material quality, and balancing compliance. Check for surface defects, proper marking, and alignment with provided documentation. Request a third-party inspection if needed, and ensure all accompanying certificates, such as ISO 1940 balancing reports, are included. Document any discrepancies before acceptance to facilitate resolution.
