Fully Rebuild Varian TV701 SEM / 869-8938R001 Navigator Turbomolecular Pump has DN 200-ISO Inlet Flange.
Varian Agilent Turbo-V701SEM consists of a high frequency motor driving a turbine fitted with 8 bladed stages and 4 Macrotorr stages. The turbine rotates in a counterclockwise direction when viewed from the high vacuum flange end.
The Agilent TV-701SEM P/N 8698938R001 turbine is made of high-strength aluminium alloy, machined from a single block. The Macrotorr stages are in the form of four discs. The turbine rotor is supported by permanently lubricated high precision ceramic ball bearings installed on the forevacuum side of the pump. The static blades of the stator are made of stainless steel.
These are supported and accurately positioned by spacer rings. The Agilent TV701 SEM stators are in the form of selfpositioning machined discs with pumping channels and an opening restricted by the corresponding rotor discs. These are made of aluminium alloy.
During normal operation Varian TV-701 869-8938R001 the motor is fed with a voltage of 54 Vac three-phase at 715 Hz. To reduce losses during start-up to a minimum, the frequency increases according to a ramp with a higher initial voltage/frequency ratio. The pump can be water cooled or air cooled: in the first case the customer can use the dedicated channels on the pump body, in the second case an external optional fan is available. A thermistor sensor is mounted near the upper bearing to prevent the pump from overheating.
The Agilent TV701SEM Navigator pump is balanced after assembly with a residual vibration amplitude less than 0.01. The pump can operate in any position and can be supported on the high vacuum flange. The connection of the forevacuum on the side of the pump is a KF 25 NW flange.
