Option sealing air “sealing air: principle” connection
Sealing air connectors are available for MHD motors. They are attached
to the motor by simply replacing the motor flange socket cover. The
overpressure inside the motor prevents penetrating oils, aggressive
coolants, and the like from entering.
Note: When mounting the motor flange socket covers with sealing
air connector, ensure that the O-rings are properly seated.
The degree of protection required is ensured only with correct
assembly.
