1) Only possible with frequency converter motor and external frequency converter
2) To DIN 28 426 and subsequent numbers
3) Higher pressure differences are possible
4) Gas temperatures over 40 °C (104 °C) can result in a reduction of the pressure difference values; please consult Oerlikon Leybold Vacuum on this
5) system for the bearings and the gear, and must be taken into account as soon as the speed is constant for over five minutes. When operating the pump
below the minimum permissible speed for a period of time exceeding five minutes, such operation can damage the pump due to insufficient lubrication
6) The cooling water quantity can be reduced provided the temperature of the discharged water does not exceed 45 °C (113 °C)
7) Please note that the WH 700 W PFPE is equipped with two independent oil reservoir chambers. Both chambers must be filled separately, respectively
emptied separately. Moreover, the oil levels must be checked separately during operation
8) The typical operating frequency of the frequency converter is 8 kHz. The total harmonic distortion for the motor current amounts to 12% approx
