Maintenance
DANGER
_age32
In case the vacuum and pressure pump conveyed gas that was con-
taminated with foreign materials which are dangerous to health,
harmful material can reside in filters.
Danger to health during inspection, cleaning or replacement of fil-

Danger to the environment.
Personal protective equipment must be worn during the handling
of contaminated filters.
Contaminated filters are special waste and must be disposed of
separately in compliance with applicable regulations.
CAUTION
_ac
During operation the surface of the vacuum and pressure pump
may reach temperatures of more than 70 °C.
Risk of burns!
●
Prior to disconnecting connections make sure that the connected
pipes/lines are vented to atmospheric pressure
Maintenance Schedule
Note : The maintenance intervals depend very much on the individual
operating conditions. The intervals given below shall be considered as
starting values which should be shortened or extended as appropriate.
Particularly heavy duty operation, such like high dust loads in the envi-
ronment or in the process gas, other contaminations or ingress of pro-
cess material, can make it necessary to shorten the maintenance
intervals significantly.
Monthly:

Make sure that the vacuum and pressure pump is shut down and
locked against inadvertent start up
In case an inlet air filter (62, 63) is installed:
◆
Check the inlet air filter (62, 63), if necessary replace

The vanes (35) are made of special carbon and are self-lubricating.
The vanes must by no means be lubricated with oil or grease.
In case the vanes (35) are un-
damaged, the height A of all
vanes is more than 23 mm and
regular inspections in short inter-
vals are ensured:
◆
Reinsert the vanes (35) as
shown
In case a vane (35) is damaged,
its height A is less than 23 mm,
1500 – 2000 (SD) / 2000 – 3000
(SV) operating hours have passed
since the last change or will have
passed until the next inspection:
◆
Insert new vanes (35) as
shown
●
Reattach the cylinder cover
Overhaul
CAUTION
_a
In order to achieve best efficiency and a long life the vacuum and
pressure pump was assembled and adjusted with precisely defined
tolerances.
This adjustment will be lost during dismantling of the vacuum and
pressure pump.
It is therefore strictly recommended that any dismantling of the
vacuum and pressure pump that is beyond of what is described in
this manual shall be done by Busch service.
