Pump Description
The pump consists of a high frequency motor driving a turbine. The
turbine rotates in an anticlockwise direction when viewed from the
high vacuum flange end.
The turbine is made of high-strength aluminium alloy, machined from
a single block.
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 stators are supported and accurately
positioned by spacer rings.
The Macrotorr stators are in the form of self-positioning 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 Vrms
three-phase at 761 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 pump must be always water cooled using the dedicated channels
on the pump body.
Minimum required water flow is 200 l/h and the water temperature
must be between +10°C and + 20°C.
Select WATER COOLING setting (Navigator Controller: WIN 106 = 1, Rack
NOTE
Controller: WIN 102 = 1) when pumping NITROGEN or lighter gases (in this case
the max power is 400 W).
Select AIR COOLING setting (Navigator Controller: WIN 106 = 0, Rack Controller:
WIN 102 = 0) when pumping ARGON gas (in this case the max power is 260 W).
