2. Condensate and waste oil drain (picture
When the pump is operating, it is imperative that the occurring
condensate/oil mixture is let off by opening the ball cocks (W)
regularly. As a standard, a level checking (V
switches off the pump automatically at corresponding level.
3. Changing blades (pictures
The blades (6 pieces) can be changed as follows:
Unscrew the screws (s ) on the motor flange (n). Pull off the
5
motor (m) together with the motor side coupling half (q). Remove
the circlip (l ), pull off the coupling (q
1
the pumpshaft. Remove the fan cover (v
of the key-way. Remove bearing cover (e) and housing cover (b)
with gaskets. Remove the blades (d) and check.
Blades (6 pieces) must be changed completely.
Oil blades slightly before assembly. Blades should move easily
in rotor slots.
Re-assemble in reverse order.
4. Air filtration (picture )
The capacity of the pump can be reduced if the air inlet
filters are not maintained correctly.
The mesh filter (f) and additional separators (Z
emptied and cleaned regularly depending upon the amount of
contamination or the filter inserts must be replaced completely.
Unscrew the screws (s ). Remove angle flange (S) with gasket.
1
Remove mesh filter (f) and clean by blowing out with compressed
air or replace. Re-assemble in reverse order.
5. Oil separation (pictures
Extremely blocked filter elements will result in an
increased pump temperature and will cause discol-
ouration of the lubricant.
The oil separator elements may become contaminated after a
long period of operation which can result in high pump tempera-
ture and motor overload. We therefore recommend to change the
filter elements (t ) every 2000 operating hours or depending upon
2
the pollution of the sucked in medium, often it is not possible to
clean these elements.
To change filters: Unscrew the screws (s
Remove the filter elements (t ) and exchange. Gaskets can be
2
re-use.

6. Oil metering pump (pictures
The oil metering pump is preset to the required output, at the factory.
This rate can only be changed on request to our Company.
If however it is neccessary to change this
rate on request, it can be achieved as
follows:
Unscrew oil tank (Y) with gasket. Un-
screw oil pump cover (L ). The rate can
1
only be changed by turning the regulat-
ing screw (L ). Reduce oil counter-clock-
2
wise, increase oil clockwise. The capac-
1
ity will be changed about / per revolu-
6
tion.
