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
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
34].

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.
