Key Features

• Universal Standard: A direct replacement for the ubiquitous Burgmann M3N / M32 / M37N series, one of the most widely used component Burgmann mechanical seal designs globally.

• Simple & Robust: Features a single conical spring design that is inherently robust and self-cleaning, making this Burgmann M3N mechanical seal ideal for general industrial duties.

• Versatile Application: Fits thousands of centrifugal pump models from KSB, Grundfos, and other major OEMs. This Burgmann mechanical seal handles water, oil, and mild chemicals.

• Torque Transmission: The conical spring grips the shaft to transmit torque, eliminating the need for drive pins or set screws that can slip or damage the shaft on Burgmann M32 and M37N seals.

• Self-Aligning: The flexible design allows the rotary face to adjust automatically to shaft end-play and minor misalignment—a key advantage of the Burgmann M3N mechanical seal design.
