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 750 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 + 30 °C.
Select WATER COOLING setting (WIN 106 = "1") if the water temperature is
NOTE
≤ 25 °C (in this case the max power is 350 W). Select AIR COOLING setting
(WIN 106 = "0") if the water temperature is 25 °C< T ≤ 30 °C (in this case the
max power is 300 W).
A thermistor sensor is mounted near the upper bearing to prevent
the pump from overheating.
The pump is balanced after assembly with a residual vibration
amplitude less than 0.01 μm.
The pump can operate in any position and can be supported on the
high vacuum flange. The connection of the forevacuum on the side of
the pump is a KF 25 NW flange.
