Import Conical Spring Mechanical Seal — Buy in Bulk from Supplier in China

The Conical Spring Mechanical Seal from Asinoseal Co., Ltd is a single-spring, pusher-type seal designed to replace the Burgmann M3N in rotating equipment. It features a conical spring geometry that maintains consistent face loading under varying pressure and shaft movement, improving seal life in dynamic applications. The seal is constructed with a stationary carbon graphite face and a rotating silicon carbide ring, matched for low friction and thermal stability.

Standard sizes range from 10 mm to 80 mm bore diameter, with common configurations for pumps and compressors in chemical and water treatment industries. The seal housing is typically cast iron or stainless steel, and the secondary seals are EPDM or FKM elastomers, selected based on chemical compatibility. Typical operating limits are up to 16 bar pressure, 150°C temperature, and 15 m/s sliding speed. The conical spring design reduces axial space requirements compared to helical springs, allowing retrofitting into compact housings.

This seal is purchased by maintenance departments in oil and gas, wastewater, and chemical processing plants where leak prevention is critical. Buyers often require it for centrifugal pumps, mixers, and agitators handling corrosive fluids. Trade terms are FOB Shanghai or CIF upon request. MOQ is one unit, and lead time is typically 15 to 25 days after order confirmation. Buyers should confirm shaft diameter tolerance, pressure class, and fluid compatibility before ordering.

Asinoseal Co., Ltd is a manufacturer located in Zhangjiagang, Jiangsu Province, China, specializing in mechanical seals for industrial pumps and rotating equipment. The company is verified as a harbor-tier supplier, indicating documented export activity. Its profile does not state years in operation, employee count, revenue, or client names. The listing confirms direct manufacturing of conical spring seals and references compatibility with the Burgmann M3N, suggesting design replication rather than original engineering.

The supplier has no recorded response rate or average response time, indicating no active customer service infrastructure. This does not imply poor product quality but suggests buyers must rely on technical documentation and third-party verification. No certifications such as ISO 9001 or API 682 are claimed in the source data. Buyers should treat this as a factory-direct supplier with limited post-sale support and confirm all technical claims through independent testing.
