Pfeiffer Turbo Pump TMH 301 P has a wear free permanent magnetic bearing at the high vacuum side and an oil lubricated ceramic bearing at the backing side. The Turbo Pumps TMH and TMU models are identical in terms of design. They only differ in their intake flange.
The Pfeiffer TMH 301 P turbo pumps may only be used for the purpose of generating vacuum. They may only be used to pump those media against which they are chemically resistant. For other media the operator is required to qualify the pumps for the processes involved. If the process produces dust, the maintenance intervals must be specified accordingly and sealing gas must be used (only for version "P"). If the pump is to be operated with more than 50 percent of the permissible gas load, sealing gas must be used (only for version "P").
