Welcome to the BURGMANN Sealing World
Double-shaft seal
  • mechanical seals in a common housing to seal one inner solid shaft and one outer, counter-rotating hollow shaft. An example of such an application is the sealing of agitators for blending inhomogeneous products, e.g. in the paint industry (see photo).
  • For axially parallel shafts: A combination of two mechanical seals in a common housing.
    An example of such an application is the sealing of screw shafts in twin screw extruders for the plastics industry (see photo).
