fig.25: GEA Grasso M-Series, arrangement of the (optional) oil
pump
The oil pump is an important component of the oil
circuit. It is used for pumping and distributing refrig-
erating machine oil.
The oil pump ensures that the oil is distributed to the
individual lubrication points (e.g. journal bearing, bal-
ance piston and packing gland of the compressor).
Hint!
The documentation of the oil pump
(operating manual, acceptance certifi-
cate) is an integral part of the product
documentation.

bination
fig.26: GEA Grasso M-Series, suction filter - check valve com-
bination
The suction filter - check valve combination contrib-
utes substantially to the high working reliability of the
components and the overall product.
The suction filter - check valve combination prevents
dirt particles carried by the suction flow from entering
into the screw compressor.
Hint!
The documentation of suction filter -
check valve combination is an integral
part of the compressor documenta-
tion.
