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

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-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 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) 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 [➔ 36].

2.3

Standard Features

2.3.1

Vacuum Relief ValveThe ultimate pressure is limited by a vacuum relief valve (VRE). The vacuum relief valve is adjusted
ex-works to the minimum permitted ultimate pressure shown on the nameplate (NP).
If the machine operates with a variable speed drive using the pressure control mode, the ultimate
pressure is limited electronically by the variable speed drive and the pressure control.

2.3.2

Pressure Monitoring
Only for the version: Pressure Control
The pressure transmitter (PSA) is to detect high inlet pressure.
The additional pressure transmitter (PSA) is to detect high process gas pressure.

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.

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 connection of the machine; 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.

NOTICE
Flow of potential condensate from the piping to the vacuum pump.
Risk of damage to the machine!
● Make sure that the vacuum pump suction and exhaust connection pipes are installed in such a
way as to prevent the flow of potential condensate from the piping to the vacuum pump.
● Busch recommends the use of the optional horizontal inlet filter and the water separator to collect the condensate and prevent it from flowing into the pump.

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):– G2 – without inlet filter (IF)– G2 ½ - with inlet filter (IF)Depending on the specific configuration ordered, other connection dimensions may apply.

8.1

Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The intervals
given below are considered as starting values which should be shortened or extended as appropriate. Particularly harsh applications or heavy duty operation, such as high dust loads in the environment or in the process gas, other contamination or ingress of process material, can make it necessary to shorten the maintenance intervals significantly.
Interval

Maintenance work

Monthly● Check the inlet screen, clean if necessary.
In case of an inlet filter (IF) being installed:● Check the inlet filter cartridge, replace if necessary.

Every 3 months● Check the oil level, see Oil Level Inspection [➔ 28].

Every 6 months● Clean the machine from dust and dirt.
In case of a coupling (CPL) being installed:● Check the coupling (CPL) for backlash and wear.

Every 20000 hours● Change the oil.
The change interval of 20000 operating hours is valid for Busch approved oils only. The change interval depends very muchon the operating conditions. Borderline operation may reducethe change interval down to approximately 5000 operating
hours. Other oils may reduce the change interval.

Every 6 years

8.2● Have a major overhaul on the machine (contact Busch).

Oil Level Inspection● Shut down the machine.
● When the machine is stopped, wait 1 minute before checking the oil level.
