The pumps comprise essentially the pump housing, a multi-stage rotor with the stator group, and the drive.
The first section of the rotor is a turbomolecular pump rotor while the second tile represents a Holweck stage. The Holweck pumping stage increases the permissible forevacuum pressure level markedly when compared with the classic turbomolecular pump.
The rotor shaft runs in two lifetime lubricated ceramic ball bearings.
The pump is driven by a split-cage DC motor. In this motor the rotor and stator windings are separated by a vacuum-tight can. Consequently the rotor runs inside the vacuum while the stator is outside the vacuum. This eliminates any need of vacuum feedthroughs. The pump is equipped with a temperature sensor and a resistor code.
Water cooling or an air cooling fan is available as optional equipment. The intake flange should be fitted with a wire mesh inlet screen to protect the pump against mechanical damage caused by foreign objects.
The pump is driven by an electronic frequency converter TURBO.DRIVE. All functions like, for example, speed control, pump sensing or temperature monitoring are monitored by the TURBO.DRIVE. This unit is powered by an external power supply.
The TURBO.DRIVE may be installed beside or underneath the pump or up to 5 m away. The pumps are equipped with a purge gas facility.
The purge gas and venting connection is blanked off by default with a M8 closure screw. A purge gas and venting valve may be connected either directly or by using a M8 – DN16KF adapter. For space reasons, when the frequency converter is installed at the side, only either the air cooler or a purge gas valve can be connected.
This item has been fully tested and is ready for a wide variety of applications.
