Varian Agilent Turbo V 70 Turbomolecular Pump TV70 9699357S002 Made in Italy

Varian Agilent Turbo V 70 Turbomolecular Pump TV70 9699357S002 Made in Italy

• The Varian/Agilent V 70 turbo pump. The pumping speed up to 68 l/s N2. Varian V 70 (9699357) has the compression ratio 5 x 108. The weight of Agilent V 70 is 1.7 kg. Rotational speed is about 75000 rpm.
• The Varian Turbo V70 9699357S002 pump consists of a high frequency motor driving a turbine fitted with 11 bladed stages. The turbine rotates in an anticlockwise direction when viewed from the high vacuum flange end.
• The Varian V70 969-9357S002 turbine is made of high-strength, light aluminium alloy, and is machined from a single block of aluminium. The turbine blades have five different angles, from 42° to 12°. 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 fabricated in stainless steel. These are supported and accurately positioned by spacer rings.
• During normal operation, the motor functions with a power feed at 54 Vac three-phase at 1250 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 external body of the TV301 pump is fitted with fins which allow the pump itself to function with natural convection air cooling. Kits are available for water cooling or forced air cooling to cool the pump in the cases where it is used under heavy load or when natural convection is insufficient for cooling purposes. A thermistor sensor is mounted near the upper bearing to prevent the pump from overheating. The thermistor sensor, the motor stator windings and the earth are connected to a Turbo-V controller through a 6 pin socket on the side of the pump. 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 or on its base. The connection of the forevacuum on the side of the pump is a KF 16 NW flange.
