Abstract

See full text

The invention concerns a mechanical seal device (1) with a mechanical seal (10) which comprises a dry-running protection device (20), the dry-running protection device (20) having at least one microsystem (21) which outputs a digital measured value (W), the microsystem (2) being arranged adjacent to the mechanical seal (10) and/or on and/or in the mechanical seal (10). The measured value (W) makes it possible to protect the mechanical seal (10) from overloads. Furthermore, the invention concerns a pump device (100) with such a mechanical seal device (1), the mechanical seal (10) being arranged in a shaft passage (102) and sitting on a pump shaft (103). Furthermore, the invention concerns a method of operating this pump device (100) in which the speed of a drive motor (105) of the pump shaft (103) is adapted on the basis of the digital measured value (W) of the microsystem (21).
