Product description
Use

The following indicative values for air can be considered:– Pa > 50 mbar, TGas < 80°C
– Pa < 50 mbar, TGas < 200°C

The COBRA BC vacuum pumps are designed for use in the field of
microelectronics and similar industries.
They can be used to suck gases and gas mixtures.
WARNING
When using toxic, inflammable and/ or explosive gases, make surethat the system corresponds in design to applicable local andnational safety regulations and that all applicable safety measures
are followed.
All product-specific safety regulations must be observed.

The vacuum pump is intended for use in a potentially non-explosive
environment.
As far as temperature is concerned, the vacuum pump is suitable for
evacuation of a 300 liters tank. The vacuum pump is not suitable forcontinuous duty at a pressure more or equal than 150 (hPa) mbar.
Caution, the operating cycle of 150 (hPa) mbar must not exceed morethan 5 min.
For other applications, contact your Busch representative.
- Maximum inlet pressure: 1 bar (abs).
- With pump running at full speed, do not expose to inlet pressure> 300 (hPa) mbar.
The vacuum pump is tight down to ultimate pressure.

Solid particles must not get into the vacuum pump. Procedural errors
can result in the pump sucking in a certain quantity of liquid. If thepump has sucked in liquid, a short drying time is necessary at the endof the procedure.

Operating principle

The allowed maximum inlet gas temperature depends on the inlet
pressure and the type of gas: the lower the inlet pressure (Pa), thehigher the drawn gas temperature (TGas) can be.

The COBRA BC 0601 G pumps are a combination of a screw vacuum
pump NW 0090 A (DP) and a Roots vacuum pump WY 0700 D (MB)BC 0601 G

The COBRA BC 0601 G vacuum pumps are COBRA NW screw
vacuum pumps with cooling water and nitrogen circuits.
The COBRA NS screw vacuum pumps are driven by water-cooled
motors.

Principle of DP vacuum pumps
The COBRA NS screw vacuum pumps work by the principle of spiral
pumps. Two parallel screws (8) rotate in opposite directions in thepump body. Entering gases are trapped between the flights of thescrews and the pump body. The gases are conveyed by the rotation of
the screws to the exhaust, where they are discharged.

of these lubricants, please carry out the filling (please refer to thevarious chapters of filling). Do not forget to connect the cooling watersupply before the first startup. Operation without these coolants canresult in damage to the vacuum pump.

Nitrogen system
The nitrogen system can be used in a number of different ways :– nitrogen is used as dilution gas. It is injected inside the cylinder on

Principle of MB vacuum pumps
The Roots vacuum pumps operate according to the approved principleof the Roots type machine. Operation is both simple and effective.
Two lobes (9) with identical profiles rotate in opposition directions within a casing. As they rotate, gas is drawn into the space between eachlobe and the casing where it is trapped and by the rotation pushed out
into the discharge. This action is repeated twice for each revolution ofeach lobe and therefore four times for each revolution of the drive
shaft. There is no mechanical contact between lobes and cylinder. So
no oil lubrication is required.
The drive motor of roots pump is a water cooled canned motor.

two different places. Nitrogen flow injected in the middle hole ispreset at 2 l/ min and can be adjusted with valve DGR 2, dependingon the application. Nitrogen flow injected in the hole on cylinder
endplate side is preset at 10 l/ min and can be adjusted with valve
DGR 1, depending on the application. When flow is too low awarning then an alarm signal is generated by flowmeter DGF to the
PLC. Status of the pump depends on the alarm function set by user
(factory setting : None, pump continues running with an alarm).
Dilution improves the screws functioning, especially when sucking
corrosive gases.
nitrogen is used as sealing gas. The nitrogen is injected between thetransmission and the process gas to achieve good closeness. The
Nitrogen flow used for the sealing is set by two chips (ɸ). With apressure of 1,5 bar, the flow is around 8-10 l/min.

Optional functions/ Use of available
accessories
A pressure sensor (PSA) mounted at the exhaust , controls theoverpressure at the exhaust. If overpressure is above 0,3 bar, pressure
sensor gives a warning then an alarm signal. Status of the pumpdepends on the alarm function set by user (factory setting : None,
pump continues running with an alarm).
A temperature sensor PT100 (TS 4) mounted on the cylinder, measures
the temperature inside the cylinder (DP).
A silencer or sound absorber (accessory) at the exhaust reduces thenoise of the pump and collects any condensate.
A leak-protection non-return valve (optional) at the exhaust traps thecondensate in the pump when the pump is switched off.
The LCD controller processes the data of the sensors as follows:

–
–
–
–
–

Gas flow checks
A pressure sensor PSA at the discharge monitors the dischargepressure. If the pressure reaches more than the limit value (alarm,preset at the factory: 0.2 bar), the purge cycle starts.

Oil circuit
Since the complete operating principle works without contact, no oil
circuit is needed in the work area.

Cooling
The vacuum pump is cooled by– a direct cooling water circuit in the motors and the DP and MB–

transmission casing. The flow regulating valve CWR of coolingwater is preset on 3-4 l/min at the factory. The water cools in the
DP and MB pumps motors, the one frequency inverter (VFD 1)
and the drive/ pump transmission DP system.
a direct cooling water circuit in the rear bearing (for exceptionallycool running in option).

PSA: exhaust pressure
TS 4: temperature inside the cylinder DP
MOT 1 and MOT 2: DP and MB current and speed
DGF: nitrogen flow rate, dilution
CWM: cooling water flow rate in motors/ transmission/ frequency
inverters

See "Installation and Maintenance Instructions, Busch PLC and Busch LCD (No.
0870758077)".

On/ Off switch
The vacuum pump is delivered with a circuit breaker. The function start/ stop canbe done in Local by using the LCD controller or in Remote by the production
machine.
