Note:
•
Pay attention to the assembly instructions for accessory
SUP-M02-xxx... (in the scope of delivery).
•
The labyrinth seal is effective only in horizontal installation
position and from approx. 200 rpm. It may only be attached
to motors with a factory-mounted shaft sealing ring.
•
Seeping fluids can lead to damage to the motor. The tightness of the
motor seal is ensured only according to the guidelines of the
corresponding motor protection class.
7.2 Sealing
Air
Connection
When the motor is to be operated under adverse conditions, a higher
protection class than the standard protection class with radial shaft
sealing ring (IP65) may be required. High demands may be made on the
tightness of motor seals when the motors are used in areas where oily
coolants are used. We recommend to use sealing air in addition to the
radial shaft sealing ring for these areas of application.
A defined excess pressure in the motor interior induced by the sealing air
connection reliably prevents the penetration of, for example, creep oils
and coolants.
