6 | 40 Instruction Manual MINK MV 0500-0600 B_EN_en
2.1 Operating Principle
The machine works on the claw principle.
The MINK is fully air-cooled thanks to an integrated fan in the drive unit.
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 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic and non-
explosive 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
representative in order to take specific precautions.
The machine is capable of maintaining ultimate pressure, see Technical Data [➔34].
The machine is not capable of maintaining ultimate pressure.
– The minimum allowed ultimate pressure is to be read from the nameplate of the machine.
– By means of process control and/or vacuum relief valves it must be made sure that the
minimum allowed ultimate pressure will not be underrun.
The machine is suitable for continuous operation.
Note: The non-return valve (NRV) is no reliable means to prevent suction and shall not be used as a
non-return valve or shut-off valve for the system.
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 [➔34].
2.3 Standard Features
2.3.1 Vacuum Relief Valve
The ultimate pressure is limited by a vacuum relief valve (VRE). The vacuum relief valve is adjusted
ex-works to the minimum permitted ultimate pressure (see nameplate).
If the machine operates with a variable-frequency drive using the pressure control mode, the
ultimate pressure is limited electronically by the variable-frequency drive and the pressure control.

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.

●Contact your Busch representative, the motor should be derated or the ambient temperature
limited.
5.2 Connecting Lines / Pipes
WARNING
Rotating Parts.
Risk of severe injury!
●Do not operate the machine without suction / discharge connection installed.
●Remove all protective covers before installation.
●Make sure that the connection lines cause no stress on the machine‘s connection; if necessary 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
efficiency. Seek advice from your Busch representative.
5.2.1 Suction Connection
Connection size(s):
– G3
Depending on the specific order, other connection dimensions may apply.
5.2.2 Discharge Connection
Connection size(s):
– R2
Depending on the specific order, other connection dimensions may apply.
●Make sure that the discharged gas will flow without obstruction. Do not shut off or throttle the
discharge line or use it as a pressurised air source.
●Make sure that the discharge line either slopes away from the machine or provide a liquid
separator 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 [➔34] and Oil [➔35].

12 | 40 Instruction Manual MINK MV 0500-0600 B_EN_en
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.
5.4 Electrical Connection (for Variable-frequency Drive)
DANGER
Live wires.
Risk of electrical shock.
●Electrical installation work must only be executed by qualified personnel.
●Make sure that the power supply for the drive is compatible with the data on the nameplate of
the variable speed drive.
●Make sure that the motor of the machine will not be affected by electric or electromagnetic
disturbance from the mains; if necessary seek advice from Busch.
●Make sure that the EMC-class of the machine confirms with the requirements of your supply
network system, if necessary provide further interference suppression (EMC-Class of the machine
see Technical Data [➔34]).
●We recommend to use gG/gL (IEC 60269-1) (class T for UL/CSA) 25 A fuses. Make sure that the
response time is below 0.4 seconds.
In case of using a residual current protective device:
●Use an all-current sensitive residual current protective device (type B).
●Electrically connect the variable-frequency drive (VFD).
