5 Functional description
5.1 Conditions of use
The vacuum pumps TOPAS D004 V - D041 V are designed for use in the commer-
cial sector, i.e. the safety equipment corresponds to DIN EN ISO 13857 table 4 for
people aged over 14 years.
The TOPAS D004 V - D041 V is suitable for the evacuation of closed systems or
for a permanent vacuum in the following suction pressure ranges:
 TOPAS D004 V - D008 V: 2 to 200 mbar (abs.)
 TOPAS D012 V - D020 V: 2 to 400 mbar (abs.)
 TOPAS D026 V - D041 V: 0,5 to 400 mbar (abs.)
For continuous operation outside of these ranges, there is a risk of oil loss
through the outlet opening. For evacuation of closed systems, the volume to be
evacuated may only be such that the maximum intake pressure can be achieved
in a few seconds.
The dependency of the suction power on the suction pressure is type-specific and
can be taken from the corresponding datasheets:
Data page No. Construction series
D161 TOPAS D004 V
D177 TOPAS D008 V
D178 TOPAS D012 V
D205 TOPAS D006 V
D270 TOPAS D020 V
D316 TOPAS D041 V
D317 TOPAS D026 V
The suctioned air may contain water vapour, but no water or other fluids. Ag-
gressive or combustible gases and vapours may not be suctioned. No hazardous
additives (e.g. combustible or explosive gases or vapours) or aggressive gases
may be suctioned.
Operation in rooms with an explosion risk is not permitted.
The ambient temperature must be between 12°C and 40°C, and the suction tem-
perature must be between 5°C and 40°C. For temperatures outside of this range,
the manufacturer should be consulted.
Counterpressures on the outlet side are only permitted up to + 0.1 bar.

5.3 Function
The pumps of the TOPAS D004 V - D041 V series are oil flooded rotary vane
vacuum pumps. You have an oil mist filter on the outlet side. The motor ventila-
tor provides cooling for the motor and pump housing. The motor and pump have
a common shaft.
When necessary, a vacuum regulating valve, additional check valve, vacuum-tight
suction filter, fluid separator, tube connection and motor circuit breaker.
The suctioned medium (air) flows through the suction filter (optional). The medi-
um fills the suction area of the pump (1). Through rotation of the rotor, the slid-
ers are pushed through centrifugal force against the internal wall of the housing,
thus forming three chambers with a consequence of different volumes, which
permit the generation of an underpressure and a flow rate.
The medium is de-oiled by the filter element and then flows out of the pump. An
oil back-suction sucks the oil separated through the filter element back into the
pump body.

6 Transport Storage
6.1 Precautions for transportation
DANGER!
Danger from suspended load
Risk of injury or death due to falling loads!
 Never stand under suspended loads.
 Maintain adequate distance to suspended loads.
 Ensure stable centre of gravity.
When lifting and transporting the machine, the safety regulations and general ac-
cident prevention regulations and the recognized technical rules must be ob-
served.
6.2 Machine lifting and transportation
The machine may only be lifted via the provided lifting eye.
The machine can swing out. When lifting pay special attention to the centre of
gravity, readjust the lifting gear!
The machinery must be properly packed in its original packaging before being
transported to the destination. The packaging should be attached to a European
pallet or similar so that the machine cannot topple over.
The packaging should protect the individual components up to their assembly,
from transportation damage, corrosion and other damage. Therefore, the pack-
aging must not be disturbed and only removed shortly before assembly.
Before each long transportation, remove the oil from the pump.
ENVIRONMENTAL DAMAGE THROUGH DISPOSAL!
Packaging material is a valuable product and can, in many cases, be re-used or
carefully prepared and re-used. Therefore:
 The packaging material must be disposed of in an environmentally friendly
manner
 Observe the local waste disposal regulations; if necessary, use the services
of a specialist disposal company.
6.3 Storage
If the vacuum pump is shut down for a longer period of time (over 3 months) or
the commissioning is delayed, the following measures must be performed:
 Dump the pump,
 Fill up corrosion protection oil, allow the pump to run for 10 minutes and
then drain off the corrosion protection oil again,
 Seal all of the openings with adhesive tape.
 Store the pump in a dry location; do not use any rooms that contain humidi-
ty or strong temperature fluctuations.
Observe the accident
prevention regulations!

7.1 Setup
The oil filling point, oil sight class and oil outlet must be easily accessible. The
cooling air inlet and the cooling air outlet must have a distance of at least 15 cm
from the adjacent walls. Emerging cooling air must not be sucked back in again.
For the components, Fig. 4 page 13.
Fig. 5 installation example
For maintenance work, a minimum distance of 0.3 m must be observed in front
of the oil filter and the oil reservoir cover.
The TOPAS D004 V – D041 V can only be operated error-free in a horizontal
setup location. The pumps must not be tilted. The setup of the vacuum pump on
solid ground is possible without anchorage. The vibrations from these rotary vane
vacuum pumps are very slight.
In the case of setup on a lower construction, we recommend anchorage via elas-
tic buffer elements.
We recommend using the threaded holes for anchoring the pump to a base
frame.
NOTICE!
For assembly at levels greater than 1000 metres above sea level, reduced out-
put is noticeable.
In this case, we advise prior advice from the manufacturer.
7.2 Installation
WARNING!
Mortal danger from electrical shocks!
Non-professional handling of electrical components can lead to life-threatening
electric shocks, if undertaken with insufficient experience.
 Electrical installations should only be undertaken by qualified personnel
 Fused security for the construction should be carried out via the main junc-
tion box.

B104 04/17 Rev.4 TOPAS D004 V - D041 V 19
8 Operation
The average sound pressure level, measured at 50 or 60 Hz operation, is given in
Section 4.2 page 11.
We recommend wearing ear protection when working permanently in the vicinity
of the operating pump to prevent damage to hearing.
Despite the most thorough oil mist separation by the air de-oiling element, the
exhaust air still contains small residues of oil aerosols which can be detected by
their odour. Long-term breathing of these aerosols could be hazardous to health.
Therefore, you must ensure good ventilation of the installation room.
HOT SURFACE!
Surface temperatures in excess of 70°C!
A
t hot operating temperatures the surface temperatures of components can rise
above 70°C. Risk of burns!
 Avoid touching the components.
 Wear protective gloves.
Before start-up of the operation, the correct set up for the machine, the installa-
tion and start-up (trial run) should be organised.
See chapter 7 „Commissioning “ page 16.
The machine should be checked prior to start-up in respect of observance of the

For maintenance work, the vacuum pump must be disconnected from the elec-
trical network by unplugging the power cord or by pressing the main switch and
securing it against restarting.
Do not perform maintenance on a pump that is still warm after operating (risk
of injury from hot machine parts or hot lubrication oil)!
9.1 Oil change
The first oil change is carried out after 500 hours of operation.
All other oil changes are as follows:
 every 500 - 2000 operating hours for TOPAS D004 V – TOPAS D020 V
 every 500 – 3000 operating hours for TOPAS D026 V / D041 V
In the case of severe dirt contamination, the oil change intervals must be re-
duced accordingly.
NOTICE!
The indicated oil change intervals are practically calculated values based on ex-
perience.
Depending on the application, the oil will become less or more contaminated;
adjust the frequency of the oil change and the type of oil selected.
