controller and a forepump and is available in three models which
differ only in the high vacuum flange.

The following figures show the three models.
Turbopump Description
The turbopump consists of a high frequency motor driving a turbine
fitted with many bladed stages and Twistorr drag 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 Twistorr stages are
in the 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 fabricated in stainless steel. These
are supported and accurately positioned by spacer rings.
The TwisTorr stators are in the form of selfpositioning machined
disks. On each disk there are parallel spiral pumping channels
designed to pump in centrifugal direction on one side and in
centripetal direction on the other side. These are made of aluminium
alloy.
