Leybold RUVAC WH 702 – outdated model
The RUVAC WH 702 is the version of the RUVAC WH 700 with a 2.2 kW motor and integrated frequency converter from the Leybold brochure of 2009. The designation WH 702 no longer appears in the current Leybold catalogues or on leybold.com; today Leybold lists this size under the name RUVAC WH 700. The nominal pumping speed to DIN 28426 is 710 m³/h at 50 Hz, 860 m³/h at 60 Hz and 1730 m³/h at the maximum frequency of 120 Hz. The permissible pressure difference in continuous operation is 75 mbar (50 Hz), 65 mbar (60 Hz) and 50 mbar (120 Hz); the nominal power consumption of the motor is 2.2 kW, 2.6 kW and 3.5 kW respectively. The pump weighs 120 kg with standard feet. The technical data are taken from the brochure “RUVAC WH / WHU” by Oerlikon Leybold Vacuum (as of 10/2009); the data column there applies to both the WH 700 and the WH 702.Order number of the RUVAC WH 702
