Shaft seals

The shaft seal for the standard blowers is provided through the specially developed FIMA turbo-labyrinth seal. The efficiency of this seal may be adapted to the particular requirements in each case by changing the number of carbon rings, the admission of purge gas or a relief line connected to the suction nozzle.
                In case of especially stringent requirements as to the shaft seal we recommend the use of gas or liquid-lubricated mechanical seals.
These sealing systems avoid leakage also at stand-still and reduce the quantity of purge medium required.
