2.1 Operating Principle
The machine works on the claw principle.
The MINK is fully air-cooled thanks to an electrical fan.
In order to avoid solids from entering, the machine is equipped with an inlet screen (IS).
In order to avoid reverse rotation after switching off, the machine is equipped with a non-return
valve (NRV).
2.2 Intended Use
WARNING
In case of foreseeable misuse outside the intended use of the machine.
Risk of injuries!
Risk of damages to the machine!
Risk of damages to the environment!
●Make sure to follow all instructions described in this manual.
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic and non-ex-
plosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the machine
and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is designed for indoor installation, in case of outdoor installation, ask your Busch rep-
resentative in order to take specific precautions.
The machine is capable of maintaining ultimate pressure, see Technical Data [➔37].
The machine is suitable for continuous operation.
Note: The non-return valve (NRV) shouldn't be used as a non-return or shut off valve for the System.
The non-return valve is only to protect the pump.
If the machine needs to be maintained after shutdown:
●Provide an additional manual or automatic operated non-return valve in the suction line.
Permitted environmental conditions, see Technical Data [➔37].

2.3 Design Options
The design options described in the following chapters might be combined.
Please refer to the nameplate (NP) to identify the corresponding design option of your machine.
Design option Codification Example
Standard (no design option) 0 MM 0060 D 00
Aqua version A MM 0060 D 0A
Gas leakage optimized version L MM 0060 D 0L
ATEX version * E MM 0060 D 0E
* ATEX-version machines have a separate dedicated ‘ATEX Instruction Manual’ document.
2.3.1 Aqua Version
This machine is specifically equipped with:
– corrosion protection coating
– a condensate reservoir
– two condensate drains
2.3.2 Gas Leakage Optimized Version
WARNING
Media potentially dangerous.
Risk of poisoning!
Risk of infection!
●Wear appropriate personal protective equipment in case of high concentration of the medium in
the ambient atmosphere of the machine.
Please note that this option reduces gas leakages from the pump stage into the environment
or from the environment into the pump stage.
A gas tight design is not achieved with this option!
The gas leakage optimized version is a design option for applications where the process gas should
remain in the machine as far as possible.
This is a important feature for applications where the process gas is run in a closed circuit without
significant back pressure at the discharge of the pump and as little process gas as possible is re-
leased into the environment or the ambient atmosphere as little as possible contaminates the pro-
cess gas.
This machine is specifically equipped with:
●pipe work with collecting line from holes for atmospheric ventilation to the gas discharge

2 | Product Description
8 | 44 Instruction Manual MINK MV 0040-0080 D_EN_en
Requirements for a proper functioning:
Ambient pressure The gas leakage optimized machine requires an ambient pressure at
the gas discharge during the whole operation range of +/- 50 hPa
(mbar).
Leakage rate The gas leakage rate of the machine can’t be stated due to different
possible run speeds and the applied counterpressure and the condi-
tion of all involved sealings.
Thermal, electrical or mechanical overloading of the entire pump by in-
creasing the counterpressure at the discharge is not permitted and
can lead to damages.
Ambient environment Closed air cooling systems are not suitable and therefore prohibited.
●Make sure that the machine is sufficiently vented (see Installation
Conditions [➔11]).
2.3.3 ATEX Version
Please refer to the specific MINK ATEX Instruction Manual part no.: 0870 234 413
2.4 Optional Accessories
2.4.1 Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The inlet filter
is available with a paper or polyester cartridge.
2.4.2 Pressure Transmitter
A pressure transmitter is available to control the pressure on the suction side of the machine.
2.4.3 PC-Software
For parameter settings with personal computers a PC-software and appropriate connection cable
can be provided.
2.4.4 Manual Control Unit
Control panel can be used for simply controlling the machine and parameter setting in the field.
2.4.5 Fieldbus Option Board
The machine can be upgraded with fieldbus option boards with different fieldbus systems.

WARNING
Suspended load.
Risk of severe injury!
●Do not walk, stand or work under suspended loads.
●To find out the weight of the machine, refer to the chapter Technical Data [➔37] or the name-
plate (NP).
●Make sure that the eye bolt(s) (EB) is/are in faultless condition, fully screwed in and tightened by
hand.
●Check the machine for transport damage.
If the machine is secured to a base plate:
●Remove the machine from the base plate.

4 | Storage
10 | 44 Instruction Manual MINK MV 0040-0080 D_EN_en
4 Storage
●Seal all apertures with adhesive tape or reuse provided caps.
NOTICE
Long storage time.
Risk of damage to the machine!
●Due to a long storage time the capacitors of the variable speed drive can lose efficiency because
of electrochemical processes. In the worst case, it can lead to a short-circuit and therefore to a
damage to the variable speed drive of the machine.
●Connect the machine every 18 months for 30 minutes to the mains.
If the machine is to be stored for more than 3 months:
●Wrap the machine in a corrosion inhibiting film.
●Store the machine indoors, dry, dust free and if possible in original packaging preferably at
temperatures between 0 ... 40 °C.

5.2 Connecting Lines / Pipes
WARNING
Rotating Parts.
Risk of severe injury!
●Do not operate the machine without suction connection installed.
●Remove all protective covers before installation.
●Make sure that the connection lines cause no stress on the connection of the machine; if neces-
sary use flexible joints.
●Make sure that the line size of the connection lines over the entire length is at least as large as
the connections of the machine.
In case of long connection lines, it is advisable to use larger line sizes in order to avoid a loss of effi-
ciency. Seek advice from your Busch representative.
5.2.1 Suction Connection
NOTICE
Ingress of foreign objects or liquids.
Risk of damage to the machine!
If the inlet gas contains dust or other foreign solid particles:
●Install a suitable filter (5micron or less) upstream from the machine.
Connection size(s):
– G1 1/4
5.2.2 Discharge Connection
NOTICE
Discharge gas flow obstructed.
Risk of damage to the machine!
●Make sure that the discharged gas will flow without obstruction. Do not shut off or throttle the
discharge line or use it as a pressurized air source.
Connection size(s):
– G3/4
Unless the aspirated air is discharged to the environment right at the machine:
●Make sure that the discharge line either slopes away from the machine or provide a liquid sep-
arator or a siphon with a drain cock, so that no liquids can flow back into the machine.

5.3 Filling Oil
NOTICE
Use of an inappropriate oil.
Risk of premature failure!
Loss of efficiency!
●Only use an oil type which has previously been approved and recommended by Busch.
For oil type and oil capacity see Technical Data [➔37] and Oil [➔38].
The oil level should stay constant over the lifetime of the oil. If the level does fall, this indicates a leak
and the machine requires repair.
