Jiaxing Burgmann Mechanical Seal offers the 108U Single Spring
Seal, a top - notch solution for chemical pumps.
This seal has a single - end face design, which simplifies
installation and maintenance. The single - spring mechanism
provides stable elastic force, ensuring a tight seal with a fixed
rotation direction for optimal performance.
It can handle shaft diameters from 18mm to 100mm, operates at
temperatures between - 10°C and 150°C, and withstands a linear
velocity up to 15m/s, adapting to various chemical processes.
Material selection is outstanding. The rotating ring uses wear -
and corrosion - resistant SiC or TC. The stationary ring offers
choices like Carbon, SiC, and TC. Auxiliary seals come in materials
such as NBR, EPDM, FFKM, Aflas, and PTFE for chemical
compatibility. Springs and metal parts are made of high - quality
stainless steel (SS304, SS316) for durability.
Suitable for transporting acids, alkalis, and organic solvents in
the chemical industry, as well as applications in water treatment
and food sectors, the 108U Single Spring Seal ensures reliable,
long - term sealing, protecting your processes and equipment.
Features:
1. Single face plus framework oil seal
2. Independent direction of rotation.
3. Multi-springs do not contact with the medium against blocking.
4. Easy for installation and maintenance.
5. Excellent wear-resistant friction pairs.
6. Double-balanced structure on the side of the medium.
7. Short inboard length.
8. Compensated by the mating ring.
9. Low-pressure circulating water is introduced between the primary
seal and oil seal, which improves the lubrication of the first seal
and carries off the friction heat and leakage.

Advantages:
• Spring unit averted from the product so no sticking and clogging
of the springs
• Safe operation (no fractures) because of seal face locking by
square pin
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design
Application:
• Water and waste water technology
• Chemical industry
• Refining technology
• Dirty, abrasive and solid containing media
• Fugitive hydrocarbons (no API seal!)
• Sticky and stringy media
• Chemical standard pumps
• Sewage pumps
