By using combination pumps, it ispossible tohave
independent circuits without the need for splitter
gearboxes.
When ordering combination pumps, the type designations
ofthe 1st and 2nd Pumps must belinked bya"+".
Order example:
A1VO035DRS0C200/10BRVB2S51B2S500-0+
A1VO035DRS0C200/10BRVB2S51000000-0
A tandem pump, with two pumps ofequal size,
ispermissible without additional supports, assuming that
the dynamic mass acceleration does not exceed
maximum10 g (= 98.1 m/s
2
).
For combination pumps consisting ofmore than two
pumps, the mounting flange must becalculated for the
permissible mass torque.
