Bosch Rexroth AG, RE 92650/2020-03-03
24 A1VO Series 10 | Axial piston variable pump
Installation instructions
1) Because complete air bleeding and filling are not possible inthis
position, the pump should beair bled and filled inahorizontal
position before installation.
Above-reservoir installation
Above-reservoir installation means that theaxial piston unit
isinstalled above theminimum fluid level ofthereservoir.
Toprevent the axial piston unit from draining inposition 8,
the height difference h
ES min
must beat least 25mm.
Observethe maximum permissible suction
heighth
Smax
=800mm.

Notice
Port F ispart oftheexternal piping and must beprovided
onthe customer side tomake filling and air bleeding
easier.
Inside-reservoir installation
Inside-reservoir installation iswhen theaxial piston unit
isinstalled inthe reservoir below theminimum fluid level.
The axial piston unit iscompletely below thehydraulic fluid.
If theminimum fluid level isequal toor below theupper
edge ofthepump, see chapter "Above-reservoir
installation".
Axial piston units with electrical components (e.g., electric
control, sensors) may not beinstalled inareservoir below
the fluid level.
