The Burgmann MG12 mechanical seal is a robust, single-spring elastomer bellows seal designed for general-purpose industrial applications. As a direct replacement for the EagleBurgmann MG12 series, this seal features a unique extended bellows tail that ensures the fitting length complies with the EN 12756 standard when paired with a G6 or G60 seat.
Key Features
• MG12 Evolution: A robust elastomer bellow seal similar to the Burgmann MG1 but with an extended tail for specific pump dimensions (L1k length).
• Dry-Run Variant: This specific model is configured with special face materials to handle dry running or poor lubrication conditions.
• Universal Fit: Fits standard cylindrical shafts without requiring a shaft step, making it easy to retrofit.
• Bellow Protection: The elastomer bellow covers the shaft, protecting it from corrosion and wear, while transmitting torque through friction grip.
• Dry Face Technology: Utilizing specific Carbon grades that can operate without a continuous liquid film, ideal for top-entry mixers or pumps that may run dry briefly.
We understand that standard solutions don't always fit. We offer extensive customization for the Burgmann MG12 mechanical seal to meet your exact needs:
Material Combinations: Choose from a variety of elastomer bellows materials (NBR, EPDM, FKM/Viton) and face materials (Carbon, SiC, TC) to match your specific fluid, temperature, and chemical compatibility requirements.
Size Adaptations: Single dry mechanical seals are available in standard shaft sizes. We can also manufacture non-standard sizes to fit legacy equipment or unique pump designs.
Special Configurations: Options include different spring types, metal hardware (SS304, SS316), and the inclusion of anti-rotation pins or drive lugs as per your specification.
The Burgmann MG12 mechanical seal is versatile and suitable for a wide range of industries and equipment:
Agitators & Top-Entry Mixers: single dry mechanical seals are ideal for chemical, pharmaceutical, and food processing mixers where dry running in the vapor space is common.
Centrifugal Pumps: Used in standard ANSI/ISO process pumps handling water, mild chemicals, and other fluids.
Wastewater & Slurry Pumps: Its debris-tolerant design makes it suitable for pumps handling water with low solids content.
General Industrial Services: A reliable choice for sealing in HVAC, water supply, and various OEM pump applications.

FAQs
Q: Is MG12 longer than MG1?
A: Yes, the MG12 has a longer "tail" (bellows mounting length) than the MG1. You must check your shaft length availability before ordering.
Q: Is this a direct replacement for the original Burgmann MG12?
A: Yes, our Burgmann MG12 mechanical seal is designed as a direct drop-in replacement. It matches the original dimensions, materials, and performance specifications, ensuring a hassle-free installation.
Q: Can this seal run completely dry?
A: The Burgmann MG12 is designed for dry and semi-dry running conditions, such as in mixer vapor spaces. For extended, continuous dry running with no fluid presence, specific face material combinations (like carbon graphite) are recommended; please consult with our technical team.
