The Agilent TV 81M turbo pump has the pumping speed up to 77 l/s N2. Agilent TV 81M (9698901) has the compression ratio 3 x 108. The weight of Agilent TV 81-M is 1.99 kg.
The Varian TV 81M Turbo Pump consists of a high frequency motor driving a turbine fitted with 9 bladed stages and 3 Macrotorr stages.
The Agilent Turbo Pump / 969 8901 turbine rotates in a counterclockwise direction when viewed from the high vacuum flange end. The V81M turbine is made of high-strength aluminium alloy, machined from a single block.
The Agilent TV81 or Varian V81 Macrotorr stages are in the form of three 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 Varian Macrotorr pump stators are in the form of selfpositioning machined discs with pumping channels and an opening restricted by the corresponding rotor discs.
Agilent 969 8901 is made of aluminium alloy.
During normal operation turbomolecular pump the motor is fed with a voltage of 54 Vac three-phase at 1350 Hz (max). To reduce losses during start-up to a minimum, the frequency increases according to a ramp with a higher initial voltage/frequency ratio.
The TV 81 pump can be water cooled or air cooled: in the first case the customer can use a dedicated external plate made of nickel-plated brass, 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 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 16 NW flange.
