DO Type 500-1425mm Floating Seal
The DO Type 500-1425mm Floating Seal is a rotating shaft seal designed for heavy-duty industrial equipment, constructed from high chrome alloy casting iron with a hardness range of HRC60 to HRC72. Its dimensions span from 500mm to 1425mm in diameter, allowing compatibility with a variety of pump and mixer housings. The seal is engineered for continuous operation under high pressure and abrasive conditions, with a rated service life of up to 4000 hours based on standard operating parameters.
The seal incorporates replaceable O-rings made from NBR, VMQ, HNBR, or FPM elastomers, selected based on fluid compatibility and temperature exposure. These materials are standard in industrial sealing applications where resistance to oils, solvents, or moderate heat is required. The casting iron body provides superior wear resistance compared to standard carbon steel seals, and the surface finish is typically ground to a Ra value under 0.8 micrometers to reduce friction and leakage risk.
This seal is commonly purchased by manufacturers of wastewater treatment systems, mining slurry pumps, and heavy machinery maintenance teams. Buyers typically order in batches of 10 to 50 units depending on equipment downtime schedules. Trade terms are negotiated directly with the supplier; standard packaging includes individual cardboard boxes with desiccant, and shipping is commonly arranged under FOB Tianjin or CIF terms. Lead time is confirmed per order and varies with production scheduling.

Sourcing DO Type 500-1425mm Floating Seal from Beijing Zhongnuo Sealing Technology Co., Ltd. - China Import Guide
Before ordering, verify the material composition of both the casting iron body and the O-ring elastomer with a certificate of analysis. Confirm the hardness range is tested per ASTM E18 and that the dimensional tolerances match your equipment’s housing specifications. Request a sample for fit and function testing, especially if replacing seals in critical machinery. Do not rely on supplier claims without independent validation.
Confirm the Incoterms with the supplier - FOB Tianjin is common, but CIF may be available. Lead time is not stated and must be negotiated per order; allow 30 to 45 days for production and export documentation. Payment terms are typically T/T 30% advance and 70% before shipment. Ensure the supplier provides an export invoice, packing list, and bill of lading in English. Request a commercial invoice that lists HS code 8484.10 for customs clearance.
Inspect each seal upon arrival for surface cracks, uneven grinding, or O-ring misalignment. Perform a dimensional check with calipers and verify hardness with a portable Rockwell tester if possible. Check for rust or moisture damage in packaging. Retain samples for future reference. Request batch-specific test reports for hardness, surface finish, and material composition. Retain all documentation for warranty claims or liability purposes.
