Agilent Technologies / Varian SQ 158 Controller for the Turbo V 70D Turbo Pump

The Agilent Technologies / Varian Turbo V70D Turbo Pump consists of a high frequency motor driving a turbine fitted with 7 bladed stages and 4 Macrotorr stages. The turbine rotates in a counterclockwise direction when viewed from the high vacuum flange end. The turbine is made of high-strength, light aluminum alloy, and is machined from a single block of aluminum. The turbine blades have five different angles, while the Macrotorr stages are in the form of discs. The turbine rotor is supported by permanently lubricated high precision ceramic ball bearing installed on the forevacuum side of the pump.
