Agilent Technologies TV801 Navigator Turbo Pump Controller

The TV 801 Navigator Turbo Pump Controller is designed to be used with the TV 801 Turbo Pump.

The TV 801 Navigator pumping system consists of a pump with a dedicated controller fixed to it. The system is available in four models and the models differ only in the high vacuum flange.

The pump consists of a high frequency motor driving a turbine fitted with 8 bladed stages and 4 Macrotorr stages. The turbine rotates in an counterclockwise direction when viewed from the high vacuum flange end.

The turbine is made of high-strength aluminium alloy, machined from a single block.

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 Macrotorr 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, 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.

This Agilent TV801 Controller is in great condition.
