Single pump with through drive
If no further pumps are to be mounted at the factory,
thenthe simple type designation is sufficient.
The scope of delivery includes:
▶ For all through drives: coupling, fixing screw, seal and
if applicable an intermediate flange
It is advisable to couple no more than three single pumps
in series.
All attachment pumps must match the ATEX classification
for the application in question.
Combination pumps
Independent circuits are available for the user when
further pumps are built on.
If the combination pump comprises 2 Rexroth axial piston
pumps and if this is supplied pre-assembled, the two type
designations are to be linked with "+".
