- CF-160 inlet Flange
The Turbo-V550 pump consists of a high frequency motor driving a turbine fitted with 8 bladed stages and 4 Macrotorr stages. The turbine rotates in an anticlockwise direction when viewed from the high vacuum flange end.
The turbine is made of high-strength, light aluminium alloy, and is machined from a single block of aluminium. The turbine blades have six different angles, from 40° to 16°, while the Macrotorr stages are in form of 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 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 56 Vac three-phase at 700 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 pump is shaped so that the pump can 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.
