TYPE M3N

The Sealergy Seals Type M3N is a mechanical seal that is a direct replacement for the industry-standard Burgmann M3N. It is a single, unbalanced seal with a rotating conical spring, known for its versatility, reliability, and cost-effectiveness in a wide range of industrial applications. As a widely recognized industry standard, the M3N is easily interchangeable with seals from many other manufacturers, which simplifies procurement and replacement. The M3N is an economical seal that is easy to install and maintain. Its simple design is free of set screws, which helps to prevent damage to the shaft. This simplicity contributes to reduced downtime and lower overall costs. The single, rotating conical spring design of the M3N provides reliable sealing and is less prone to clogging than multi-spring designs. This makes it a suitable choice for applications with a low solids content in the fluid. The M3N is widely used in industries such as pulp and paper, chemical processing, water and wastewater technology, and building services. It is particularly suited for circulating pumps, heating systems, compressors, mixers, and blenders. Depending on the materials used for its components, the seal can handle a wide range of operating conditions, including temperatures from -20 °C to 180 °C, pressures up to 10 bar, and speeds up to 15 m/s.

• Pressure: Up to 10 bar (145 PSI). Some sources indicate up to 25 bars.
• Unbalanced.: Yes
