Introduction
Congratulations on your purchase of the Busch vacuum pump. With
watchful observation of the field’s requirements, innovation and steady
development Busch delivers modern vacuum and pressure solutions
worldwide.
These operating instructions contain information for
–product description,
–security,
–transport,
–storage,
–installation and commissioning,
–maintenance,
–overhaul,
–troubleshooting
of the vacuum pump.
For the purpose of these instructions, “handling” the vacuum pump
means the transport, storage, installation, commissioning, influence on
operating conditions, maintenance, troubleshooting and overhaul of
the vacuum pump.
Prior to handling the vacuum system, these operating instructions
shall be read and understood. If anything remains to be clarified
please contact your Busch representative!
Keep these operating instructions and, if applicable, other pertinent
operating instructions available on site.

Product Description
Use
The COBRA NC vacuum pumps are designed for use in the field of
industrial applications and similar industries.
They can be used to draw gases and gas mixtures and hydrocarbon
gases.
WARNING
When using toxic, inflammable and/ or explosive gases, make sure
that the system corresponds in design to applicable local and
national 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.
The maximum admissible temperature of drawn gas depends on the
inlet pressure and the nature of the gases. The lower the inlet pressure
(Pa), the higher can be the drawn gas temperature (TGas). We can
consider as air the following indications:
–Pa < 50 mbar, TGas <200°C
–Pa > 50 mbar, TGas < 70°C
Max. permissible number of starts per hour: 6
The vacuum pump is suitable for continuous operation at any inlet
pressure between atmospheric pressure and ultimate pressure.
Principle of operation
The COBRA NC vacuum pumps are screw vacuum pumps with a
cooling liquid circuit.
The COBRA NC vacuum pumps operate according to the principle of
screw pumps. Two parallel screws rotate in opposite directions in the
pump body. Entering gases are trapped between the pitches of the
screws and the pump body. The gases are conveyed by the rotation of
the screws to the exhaust side where they are discharged.
The COBRA NC vacuum pump is driven by an air-cooled motor.
Cooling
The vacuum pump is cooled by a cooling liquid inside the cooling liquid
chambers of the cylinder and the inlet side end plate (B- side).
The screw rotors cooling must be made with cooling liquid injection
(INJ) in the cylinder.
NOTE
Before first start-up of the vacuum pump, check the oil level, correct
if needed.
Do not forget to connect the cooling liquid supply before the first
start-up.
Operation without oil and cooling liquid can result in damage to the
vacuum pump.

Maintenance
DANGER
In case the vacuum pump has conveyed gases that have been
contaminated with foreign materials that are dangerous to health,
the oil and condensates will also be contaminated.
These foreign materials can infiltrate the pores, recesses and other
internal spaces of the vacuum pump.
Danger to health when the vacuum pump is dismantled.
Danger to the environment.
Always wear protective clothing when carrying out maintenance
work.
CAUTION
Only authorised personnel may carry out any dismantling on the
vacuum pump. Before work begins, the operator of the vacuum
pump must fill in a form or a “Declaration of Decontamination” that
provides information on possible dangers and appropriate measures.
If this form has not been filled in completely and signed by a
responsible person, the vacuum pump may not be dismantled.
CAUTION
Before any maintenance work is started, a safety perimeter of at
least 1m around the machine must be set up.
CAUTION
During operation the surface of the vacuum pump may reach a
temperatures of 90° C.
Risk of burns !
CAUTION
The oil temperature can reach a value of 100°C!
Danger of burns!
lLeave the vacuum pump to cool down prior to any action that
requires touching the vacuum pump
lPrior to disconnecting inlet and outlet pipes, make sure that all
piping is vented to atmospheric pressure
Maintenance program
NOTE: The maintenance intervals depend on the individual operating
conditions. The intervals given below should be considered as initial
guidelines which should be shortened or extended as appropriate. In
particularly heavy duty operation such as high dust loads in the
environment or in the process gas, it can become necessary to shorten
the maintenance intervals significantly.
Monthly:
lCheck the oil level (see “Checking the Oil”)
lCheck the vacuum pump for oil leaks - in case of leaks, have the
vacuum pump repaired (Busch service)
lCheck the vacuum pump for cooling liquid leaks - in case of leaks,
have the vacuum pump repaired (Busch service)
Yearly:
In case of operation in a dusty environment:
uMake sure that the operating room is clean and free of dust;
clean the room if necessary
lMake sure that the vacuum pump has been switched off and that
it cannot accidentally be switched on again
lCheck the electrical connections
lCarry out a visual inspection of the vacuum pump
If the inlet is equipped with a mesh screen:
uCheck the mesh screen at the inlet and clean it if necessary
lCheck the correct operation of the measurement and safety
equipment
Every 5'000 operating hours:
lChange the oil (see “Changing the Oil”)
Every 10’000 operating hours:
lCheck the seals and replace them if necessary
lCheck the inlet and discharge lines and clean or replace them if
necessary
lCheck the external look of the oil lubrucated mechanical seals. If
they are worn or damaged, replace them.
Every 16’000 operating hours, at the latest
after 4 Years:
Have a major overhaul done on the vacuum pump (Busch service)
Checking the oil
Checking the oil level
lCheck the oil level on the two oil sight glasses. This can be done

Maintenance
Page 9

lMake sure that the filling level is between the Min and Max of the
oil sight glass (OSG)
If the oil level is below the required level:
uTop up with oil (see “Topping up Oil”)
If the oil level is above the required level:
uCheck the evacuation of the condensates at the pump exhaust
uDrain the oil (see “Draining oil”)
Topping up with oil
NOTE: Under normal conditions there should be no need to top up
with oil in-between the recommended oil change intervals. A
significant drop in the oil level indicates a malfunction (see
“Troubleshooting”).
CAUTION
Risk of injury (burns) with open oil filler orifice.
Risk of injury in case of badly screwed-in plugs.
Remove the oil filler plugs only when the vacuum pump is stopped.
The vacuum pump must only be operated when the oil filler plugs
are firmly tightened up and do not leak.
lMake sure that the vacuum pump is switched off and cannot
accidentally be switched on again
lRemove the oil filler plugs (OFP)
lTop up with oil
lMake sure that the filling level is between the Min and Max of the
two oil sight glasses (OSG)
lMake sure that the seals of the oil filler plugs are not damaged and
replace plugs if necessary
lRefit the oil filler plugs and tighten up
Life-span of the Oil
The oil life depends very much on the operating conditions. Under
normal conditions the oil must be changed every 5000 operating hours
or after 12 months, whichever comes first.
Under very unfavourable operating conditions the oil life can be less
than 500 operating hours. A very short oil life time indicates either a
malfunction (see “Troubleshooting”) or unsuitable operating
conditions.
If there is no experience available regarding the oil life under the
prevailing operation conditions, it is recommended to have the oil
analysed every 500 operating hours and thus to establish the oil
change interval accordingly.
Changing the oil
WARNING
In case the vacuum pump has conveyed gases that have been
contaminated with harmful foreign materials, the oil will also be
contaminated.
Danger to health during the change of contaminated oil.
Danger to the environment.
Wear protective equipment during the change of contaminated oil.
