The Model M7N is a standardized cartridge-mounted multi-spring mechanical seal designed for general industrial pump applications. It features a corrosion-resistant stainless steel assembly with multiple helical springs that provide uniform face loading and compensate for minor shaft misalignment. The seal utilizes a balanced design with primary sealing faces of reaction-bonded silicon carbide versus premium carbon graphite, ensuring reliable performance in moderate pressure and temperature ranges. Its cartridge construction enables precise pre-set installation without requiring manual spring compression measurement. This seal is compatible with ANSI/API process pumps handling water, light hydrocarbons, and non-abrasive chemicals at temperatures up to 180°C and pressures to 15 bar. The standardized dimensions ensure interchangeability with OEM equivalents while providing consistent sealing performance in
Wave Spring, O-ring pusher mechanical seal Type M7N is a robust and highly interchangeable seals. Used in the different media conditions due to extend material options. It is ideal for use in paper industry, textile printing, chemical petroleum, shipbuilding and sewage treatment industry.

Unit: mm
A1: The multiple helical springs ensure uniform axial loading on the seal faces, compensating for minor shaft misalignment and eccentricity. This design maintains stable face contact under variable operational conditions, reducing risk of leakage due to vibration or runout.
A2: It employs reaction-bonded silicon carbide rotating against carbon graphite. This combination offers reliable performance in water, light hydrocarbons, coolants, and non-abrasive chemical services up to 15 bar and 180°C.
A3: The cartridge design integrates all components into a single pre-assembled unit. This enables quick installation without manual spring adjustment, eliminates setting errors, and ensures correct compression of the sealing faces.
A4: Yes, its standardized dimensions and material finish comply with hygienic requirements for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes, making it suitable for food, beverage, and pharmaceutical applications.
A5: The balanced design hydraulically reduces closing force on the seal faces. This mitigates heat buildup and extends service life in higher-pressure applications (up to 15 bar) by controlling interfacial pressure.
