Product description
Use
The COBRA BC vacuum pumps are designed for use in the field of mi-
croelectronics and similar industries.
They can be used to suck gases and gas mixtures.
WARNING
When using toxic, inflammable and/ or explosive gases, make sure
that the system corresponds in design to applicable local and na-
tional safety regulations and that all applicable safety measures are
followed.
All product-specific safety regulations must be observed.
Solid particles must not get into the vacuum pump. Procedural errors
can result in the pump sucking in a certain quantity of liquid. If the
pump has sucked in liquid, a short drying time is necessary at the end
of the procedure.
The allowed maximum inlet gas temperature depends on the inlet pres-
sure and the type of gas: the lower the inlet pressure (Pa), the higher
the drawn gas temperature (TGas) can be.
The following indicative values for air can be considered:
– Pa > 50 mbar, TGas < 80°C
– Pa < 50 mbar, TGas < 200°C
The vacuum pump is intended for use in a potentially non-explosive
environment.
As far as temperature is concerned, the pump is suitable for evacuation
of a 300 liters tank. The pump is not suitable for continuous duty at a
pressure more or equal than 150 mbar. Caution, the operating cycle of
150 mbar must not exceed more than 5 min. For other applications,
contact your Busch representative.
The vacuum pump is tight down to ultimate pressure.
Operating principle
COMBI
The COBRA BC 0600 F pumps are a combination of a screw vacuum
pump NW 0100 E (DP) and a Roots vacuum pump WY 0700 C (MB)
The COBRA BC 0600 F vacuum pumps are COBRA NW screw vacuum
pumps with cooling water and nitrogen circuits.
