des cri bed  be low.

In case of dis re gard risk of da mage or des truc tion of the va cuum
pump!

Risk of Inju ry!

The va cuum pump must be ope ra ted un der the condi tions described 
below.

The va cuum pump is de si gned for

the suc tion

of 

air and other dry, non-ag gres sive, non-toxic and non-ex plo sive ga -
ses

Con veying me dia with a hig her den si ty than air leads to an in crea sed

only af ter prior consul ta tion with Busch

Max.  al lo wed  tem pe ra ture  of  the  in let  gas:

See “Oil, Ambient tem pe ra ture range”

In case the va cuum pump is equip ped with a gas bal last (op tio nal) wa -

(see  “Instal la tion  and  Com mis sio ning,  Ope ra ting  No tes,  Con veying
Con den sable Va pours”). The conveyance of other va pours shall be
agreed upon with Busch.

The va cuum pump is made for the in ten ded use in po ten tial ly ex plo sive 
areas

The va cuum pump is ther mal ly sui table for conti nuous ope ra tion.

The va cuum pump is ul ti mate pres sure pro of.

CAUTION 

Du ring ope ra tion the sur face of the va cuum pump may reach tem -
pe ra tu res of more than 70 °C. 

Risk of burns! 

The va cuum pump shall be pro tec ted against contact du ring
operation. 

CAUTION 

The dis char ged air contains small quan ti ties of va cuum oil.

Staying in va cuum oil conta mi na ted air bears a risk of da mage to
health.

If air is dis char ged into ro oms where per sons stay, suf fi cient ven ti la -
tion must be provided for.

CAUTION 

The va cuum pump emits noise of high in ten si ty.

Risk of da mage to the hea ring.

Per sons staying in the vi ci ni ty of a non noise in su la ted va cuum
pump over ex ten ded pe riods shall wear ear protection.

Make sure that all pro vi ded co vers, guards, ho ods etc. are moun -
ted

Make sure that pro tec tive de vi ces will not be di sa bled.

Make sure that co o ling air in lets and ou tlets are not co ve red or
obs truc ted and that the co o ling air flow is not af fec ted ad ver se ly in 
any other way

Make sure that  the “Instal la tion Pre re qui si tes” (see “Instal la tion
Pre re qui si tes  and  Com mis sio ning”  are  com plied  with  and  will  re -

Conveying Condensable Steams

 CAUTION

ties and can cause a jam of the ro tor.

Apply a sui table ope ra ting me thod to make sure that no conden sa -
tes re main in the va cuum pump. 

In or der to use the va cuum pump for the conveyance of
conden sable va pours, the va cuum pump must be equip ped with
shut-off valve in the suc tion line and with a gas ballast valve.

The quan ti ty of conden sable steams are in di ca ted in the table “Tech ni -
cal Data”.

Ver sion with gas bal last de vice with ball-cock:

Make sure that the bal last valve (477) is open and will re main
open  du ring  ope ra tion

Ver sion with gas bal last de vice with so le noid valve:

Make sure that the so le noid valve is clo sed

NOTE

: In the case of an ope ra tion with a gas bal last de vice with a

so le noid valve, this one opens at the start of the va cuum pump in
star connec tion, this in or der to dis charge the mo tor. With the exis -
ting connec tion bet ween the oil se pa ra tor and the in let flange, the
air flow is as su red. 

The so le noid valve is clo sed when the mo tor pas ses in phase del ta
and the va cuum can thus be obtained.

Close the shut-off valve in the suc tion line

Ope rate the va cuum pump with the shut-off valve in the suc tion
line clo sed for ap prox. half an hour, so that the ope ra ting tem pe ra -
ture will rise to ap prox. 75°C

At pro cess start:

Open the shut-off valve in the suc tion line

At pro cess end:

Close the shut-off valve in the suc tion line

Ope rate the va cuum pump for ano ther ap prox. half an hour

Maintenance

 WARNING 

In case the va cuum pump conveyed gas that was conta mi na ted
with fo reign ma te rials which are dan ge rous to health, harm ful ma -
te rial can re side in fil ters.

Dan ger to health du ring ins pec tion, clea ning or re pla ce ment of fil -
