COBRA NS (DP) vacuum pump

Prepare the quantity of oil specified in the table “Oil quantity”

NOTE

: The quantity of oil specified in the installation handbook is of

informative nature only. Check the oil level with the help of the various

oil sight glasses (OSG 1, OSG 2) on the vacuum pump.

CAUTION

Before you change the type of oil, make sure that the new type is

compatible with the old type. If necessary, flush the vacuum pump.

Unscrew the oil filler cap (OFP)

Fill in oil

Make sure that the oil level is in the target circle of the oil sight

glasses

Oil level, pump not operating

Make sure that the seals of the oil filler cap are not damaged.

Replace them if necessary

Screw on the oil filler cap hermetically tight

NOTE

: It is easier to switch on the vacuum pump with cold oil when 

the intake line is not closed or when the intake flange is not covered by 

a rubber plate.

Start the vacuum pump

If the intake line is equipped with a shut-off device:

Close the shut-off device

If the intake line is not equipped with a shut-off device:

Place a rubber plate on the intake flange

Let the vauum pump run for a few minutes

Stop the vacuum pump and wait a few minutes

Make sure that the oil level still lies in the target circle of the oil

sight glasses

If the oil level is below the target circle:

Fill in more oil

If the intake line is equipped with a shut-off device:

Open the shut-off device

If the intake line is not equipped with a shut-off device:
Remove the rubber plate from the intake flange and connect the intake

line to the intake flange

CAUTION

In case of a vacuum pump  filled with oil, make sure that by lifting

the inclination angle of the vacuum pump do not exceed 5° from

the horizontal. In case of too high inclination (>5°), risk of oil leak

within the work area

Make sure before every transport using the appropriate lifting

mean that the inclination of the vacuum pump is less than 5°.

CAUTION

The vacuum pump must remain in a horizontal position when it has

been filled with oil.

WY (MB) rotary lobes vacuum pump

Prepare the quantity of oil specified in the table “Oil quantity”

NOTE

: The quantity of oil specified in the installation handbook is of

informative nature only. Check the oil level with the help of the various

oil sight glasses (OSG 3,OSG 4) on the vacuum pump.

CAUTION

Before you change the type of oil, make sure that the new type is

compatible with the old type. If necessary, flush the vacuum pump.

COBRA DS vacuum pump

Start the vacuum pump

If the intake line is equipped with a shut-off device:

Close the shut-off device

If the intake line is not equipped with a shut-off device:

Place a rubber plate on the intake flange

Let the vacuum pump run for a few minutes

Stop the vacuum pump and wait a few minutes

COBRA NS (DP) vacuum pump

Make sure that the oil level still lies in the target circle of the oil

sight glasses

If the oil level is below the target circle :

Fill in more oil

If the intake line is equipped with a shut-off device:

Open the shut-off device

If the intake line is not equipped with a shut-off device:
