1 Description
The TURBOLAB pump systems are turnkey vacuum units for pumping vacu-
um vessels to pressures in the high-vacuum range.
1.1 Design
The TURBOLAB pump systems consist of the following components as
standard:
■
Turbomolecular pump TURBOVAC
The TURBOVACs are turbomolecular pumps with lifetime lubricated ceram-
ic ball bearings. A built-in thermal switch switches off the TURBOVAC if the
permissible temperature is exceeded.
■
The frequency converter is integrated into the TURBOVAC and is supplied
with 24 VDC and controlled via RS 485 interface by the TURBOLAB.
■
Backing pump
The TRIVAC is a two-stage rotary vane pump. It is fitted with a gas ballast
valve and an anti-suckback valve. The anti-suckback valve shuts off the
vacuum line to the turbomolecular pump in the event of power failure or
when the unit is switched off.
The SOGEVAC SV 16 D and SV 25 D are single stage, oil-sealed rotary
vane pumps. The anti-suckback valve, gas ballast valve and an exhaust fil-
ter, oil return circuit are integrated functional elements of the SOGEVAC.
The SCROLLVAC pumps are dry compressing scroll pumps.
The DIVAC pumps are two to four-stage, oil-free diaphragm pumps.
Some TURBOLAB pump systems are delivered without backing pump.
■
Vacuum connection between TURBOVAC and backing pump: flexible
stainless-steel line. The connection can be broken, for example to enable
an adsorption trap to be fitted.
■
Frames: Cart with baseplate, mounting column & castors or benchtop
frame with rubber feet.
■
TPU Turbo Pressure Unit
Every TURBOLAB comes standard with the TPU for control, configuration
& monitoring of the turbomolecular pump system.
The backing pump is connected depending on the specific type at X211
(110/230VAC) or at X20 (24VDC) and it starts when the turbomolecular
pump is started.
A safety valve can be connected at X210 (110/230VAC) and this safety
valve is switched in parallel with the backing pump.
The function for the accessory connection is set by default to “Active at
Start Command” and this setting can be changed through Menu →
Accessory → VV Pump.
