Standard Multi-spring Mechanical Seal M7N

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.
