Key Features

Our replacement Burgmann M3N is crafted to meet the highest industry standards, offering several key advantages that ensure longevity and reliability in demanding industrial environments:

Dry-Run Capability: Unlike standard seals that require a liquid film, this dry running mechanical seal features specialized carbon graphite faces. These faces are designed to operate against ceramic or silicon carbide without lubrication, making them perfect for sealing vapors and gases in the upper sections of vessels.

Self-Cleaning Design: The replacement Burgmann mechanical seal utilizes a conical spring that is robust and self-cleaning. This design prevents clogging from fibers and solids, ensuring consistent performance even in dirty or viscous media.

Positive Drive: Torque transmission is achieved through the conical spring gripping the shaft directly. This eliminates the need for set screws or drive pins, which can slip or damage the shaft, providing a more secure and reliable connection.

Versatile Material Options: We offer a wide range of material combinations for the seal faces and secondary seals (O-rings). This flexibility allows the Burgmann M3N to be customized for specific chemical compatibilities and temperature requirements, from water and oil to weakly corrosive mediums.

High Performance: With an operating pressure of up to 1.4 MPa and temperatures ranging from -20°C to 120°C (with options for higher temperatures), this dry running mechanical seal is built to withstand the rigors of industrial applications.

Customization Information

We understand that every application is unique. That's why we offer extensive customization options for the Burgmann M3N to ensure a perfect fit for your specific needs:

• Material Selection: Choose from a variety of materials for the rotary and stationary rings, including Carbon, Silicon Carbide (SiC), and Tungsten Carbide (TC). Secondary seals are available in NBR, EPDM, Viton, and PTFE to match your chemical environment.

• Size Range: Our Burgmann M3N seals are available in a wide range of shaft diameters, from 6 mm to 80 mm, accommodating both standard and non-standard equipment.

• OEM/ODM Services: We provide comprehensive OEM and ODM services, allowing you to brand the seals with your own logo or request custom designs based on your technical drawings.

• Special Configurations: Whether you need a specific spring type, metal parts in SS304 or SS316, or a unique installation length, our engineering team can tailor the dry running mechanical seal to your exact specifications.

Applications

The versatility of the Burgmann M3N makes it suitable for a wide array of industries and equipment:

• Agitators and Mixers: Ideal for top-entry mixers in chemical plants, food processing facilities, and pharmaceutical manufacturing, where dry running conditions are common.

• Reaction Vessels: Perfect for sealing the head-space of reactors where vapors and gases need to be contained without liquid lubrication.

• Water and Wastewater Treatment: Used in pumps and mixers handling water, sewage, and other fluids with low solids content.

• Chemical Processing: Suitable for a variety of chemical applications, provided the materials are selected appropriately for the specific chemicals involved.

• Food and Beverage: With the right material choices, the dry running mechanical seal can be used in food-grade mixers and blenders, ensuring hygiene and preventing contamination.

FAQs

Q: Can I use a standard Burgmann M3N for dry running?

A: No! Standard M3N faces require liquid lubrication. Running them dry will destroy them in minutes. You must specify the "Dry Running" version with specialized carbon faces.

Q: What is the difference between M3N and M37N?

A: The M3N is a single seal, while the M37N is a double seal. The M37N is designed for more demanding applications where higher pressure or better leakage control is required. However, for dry running applications in mixers and agitators, the Burgmann M3N is often the preferred choice due to its simplicity and effectiveness.

Q: What materials are available for the seal faces?

A: We offer a variety of materials for the seal faces, including Carbon, Silicon Carbide (SiC), and Tungsten Carbide (TC). The choice of material depends on your specific application, including the type of fluid, temperature, and pressure. Our technical team can help you select the best material combination for your dry running mechanical seal.
