13 Technical data and dimensions
13.1 General
Basic principles for the Technical Data of Pfeiffer Vacuum Turbopumps:
● Recommendations of PNEUROP committee PN5
● ISO 21360; 2007: "Vacuum technology - Standard methods for measuring vacuum-
pump performance - General description"
● ISO 5302; 2003: "Vacuum technology - Turbomolecular pumps - Measurement of per-
formance characteristics"
● Ultimate pressure: using a test dome and a 48 hrs. period of baking out
● Gas throughput: water cooling; backing pump = rotary vane pump (10 m
3
/h)
● Cooling water consumption: at max. gas throughput, cooling water temp. 25 °C
● Integral leak rate: using a Helium concentration of 100 %, period 10 s
● Sound pressure level: Distance 1 m to the pump
Conversion table: pressure units
