* Depending on the ambient temperature, the gas throughput and the type of gas,
forced air cooling or water cooling may be necessary.
§ Please contact the supplier to discuss your specific system details and the necessary
achievements for pumping speed, compression ratio and ultimate pressure.
† For some pump classes, different pumping speeds are specified for pumps with ISO
and CF flanges, as differences in flange geometry here lead to a difference in
performance of > 5%.
‡ The compression ration of a TMP describes the performance of the TMP design for
the compression of a gas type at special conditions. The compression data were
measured only using the CF flange variants.
