NM-1 / NM-12 / NM-13 Elastomer bellows mechanical seals
Analog:
AESSEAL B02 / B012 / B013, Burgmann MG1 / MG12 / MG13, Roten L3 / L3K / L3N, Vulcan 19 / 192 / 193, Sterling SMG1 / SMG12 / SMG13, Flowserve 190 / 192 / 193, Hecker HN 410SU / 410KU / 410NU, Latty T700, KSB
This type of mechanical seal has very good secondary seal characteristics.
It is commonly used for pumps at milk plants and breweries.
We recommend that this seal be used in equipment where boiler scale formation is possible.
The other seal elements are nickel chrome steel.
Materials used for sealing faces:
- carbographite
- chromium steel
- nickel chrome steel
- increased rigidity nickel chrome steel
- tungsten carbde
- silicon carbide
- ceramics (Al2 O3)
Operating limits:
- СЂ = 12 bar
- t = -20 ... 120В°C
- v = 10 m/s
