Instruction Manual R5 KD 0012-0020 A_EN_en 5 / 24
2.1 Operating Principle
The machine works on the rotary vane principle.
The oil seals the gaps, lubricates the vanes and takes away compression heat.
Exhaust filters separate the oil from the discharged gas.
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 designed to be integrated into vacuum packaging table-top machines.
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 [ ► 20] .
Permitted environmental conditions, see
Technical Data [ ► 20]
.
The machine is suitable for intermittent periodic duty as per IEC 60034-1.
Duty type:
S3 S1
S3 60 % - = 100 cycles in series
S3 50 % - unlimited cycles in series*
Independent of the load - unlimited cycles
in series*
* (Depending on the use of the pump under these conditions, other oil types might be
more appropriate! Contact Busch for specification.)
Duty type S3:
Definition: It is a sequence of identical duty cycles, each including a time of operation at
constant load and a time deenergized and a rest.
Cyclic duration factor:
Definition: The cyclic duration factor is defined as the ratio between the periods of load-
ing, including starting and electric braking, and the duration of the duty cycle, expressed
as a percentage.
This means:
During a period of e.g. 10 minutes (100 %) the operating time of the machine is of 6
minutes (60 %) and the standstill of the machine is of 4 minutes (40 %).
