6.2 Oil Lubrication 

(see data sheets D 111 + D 117)

The pumps are despatched with the oil tanks (except fresh oil) fi lled. However 
it is advisable to check the oil levels.
Sight glass: Fresh oil (

I

), LP-bearing (

I

1

), HP-bearing (

I

2

), gearbox (

I

3

). If oil 

level is low, please refi ll. Oil fi lling points: Fresh oil (

H

), LP-bearing (

H

1

), HP-

bearing (

H

2

), gearbox (

H

3

). An oil level switch (

V

) is fi tted in the fresh oil tank 

as standard. This automatically stops the pump if the minimum oil level is 
reached (depending on actual site control installation). The pump can be re-
started after refi lling. We recommend the following oil brands: Bechem VBL 
100, BP Energol RC 100, Esso rotary oil 100, Mobil vacuum pump oil heavy, 
Shell Tellus oil C 100 or Aral Motanol HK 100. Other lubricants should only be 
used after reference to the manufacturer. The bearing and gear oil should be 
completely changed once a year. Under extrem conditions we recommend 
earlier maintenance if necessary. Oil type plate (

M

), oil drain LP-stage (

K

1

and HP-stage (

K

2

). The gearbox oil should be changed after approx. 3000 

operating hours (

K

3

).

Recommendations for cheking the fresh oil consumption: Fill up fresh oil to 
the upper level indicated on the sight glass (

I

). Operate machine for a period 

of 10 hours. Refi ll fresh oil again to the upper level.
Oil consumption = Refi ll / 10 hr

Old and used oil must be disposed of corresponding with the rel-
evant health, safety and environmental  laws.

If the oil brand is changed. The old oil must be drained completely from 
the tank and the oil cooler.

6.3 Oil metering pump

The oil metering pump is set to necessary output at the factory.

This rate can only be changed on request to our Company.

This rate can only be changed on request to our Company by turning the regulating screw. The capacity will be changed about

/

 per revolution. Reduce oil counter-clockwise, increase oil clockwise.

Before fi rst start-up of the pump, the oil fl ow should be primed by giving the oil pump handle approximately 150 
- 200 turns. This procedure should also be carried out if the pump has been stationary for a week or more, or after 

repairs to the gear unit or change of stages or after cleaning of the oil pump or the oil lines.

6.4 Initial Operation

Warning –> Start-up with pipework

At start-up, severe damage may occur if there is debris in 
the pipework.
We therefore recommend a vacuum tight inlet fi lter of 5 
micron rating is installed for start-up.

Start the pump momentarily to check the direction of rotation 
(arrow (

O

 

 D 111 + D 117)). As an option the motor coupling 

can be fi tted with a unidirectional free-wheel device to prevent 
the vacuum pump rotating in the event of incorrect motor rota-
tions.

Important:

 When the pump is handling moist or aggressive 

media, it should be run before and after the process operation 
with a closed process vacuum valve, but with an open bleed 
valve (optional item). This pre and post running should take 20 
to 30 minutes. The pre run is to bring the pump up to operating 
temperature and therefore prevent condensation of  vapours 
inside the pump. The post run is to purge the pump of residual 
media and to leave the internals with a fi lm of clean oil for the 
period it will be stationary.

7. Maintenance

When maintaining these units and having such situa-
tions where personnel could be hurt by  moving parts 

or by live electrical parts the pump must be isolated by 
totally disconnecting the electrical supply. It is imperative 
that the unit cannot be re-started during the maintenance 
operation.
Do not maintain a pump that is at its normal operating 
temperature as there is a danger from hot parts or hot 
lubricant.
Hazardous substances must be removed before serving. 
Maintenance personnel should be informed regarding the 
presence of anything harmful and also be informed about all 
relevant safety regulations before carrying out any work.

7.1 Oil Metering Pump

The lubrication oil pump requires no special attention during 
operation. Care should be taken to ensure that there is always 
suffi cient oil in the reservoir so that air is not pumped into the 
oil lines. If this should occur the oil lines must be dis-connected 
and the pump hand operated to remove all air bubbles from the 
lines before re-connecting.
At least once a year the oil pump should be cleaned out by 
pumping petroleum through it. At the same time the oil reservoir 
should be fl ushed out. This cleaning is also recommended if 
the pump has been stored for a long time after delivery before 
putting into operation as hard deposits may have formed which 
could adversely affect the pump performance.
