Hydraulic fluid
The axial piston unit A1VO isdesigned for operation
withHLP mineral oil according toDIN 51524.
Application instructions and requirements for
hydraulicfluid selection, behavior during operation
aswellasdisposal and environmental protection should
betaken from the following data sheets before the start
ofproject planning:
▶ 90220: Hydraulic fluids based onmineral oils and
related hydrocarbons
Selection ofhydraulic fluid
BoschRexroth evaluates hydraulic fluids onthebasis
oftheFluid Rating according tothe technical
datasheet90235.
Hydraulic fluids with positive evaluation inthe Fluid Rating
are provided inthe following technical datasheet:
▶ 90245: BoschRexroth Fluid Rating List forRexroth

Hydraulic fluid
Notice
The axial piston unit is not suitable for operation with
water-free HF hydraulic fluids / HF hydraulic fluids
containing water / HFx hydraulic fluids.
Filtration ofthe hydraulic fluid
Finer filtration improves thecleanliness level
ofthehydraulic fluid, which increases theservice life
oftheaxial piston unit.
A cleanliness level ofat least 20/18/15
istobemaintainedaccording toISO4406.
At ahydraulic fluid viscosity ofless than 10 mm²/s
(e.g.duetohigh temperatures during short-term
operation), acleanliness level ofatleast 19/17/14
according toISO 4406 isrequired.
For example, the viscosity is 10 mm²/s at:
▶ HLP 32 atemperature of73 °C
▶ HLP 46 atemperature of85 °C

The pressure controller limits the maximum pressure at the
pump outlet within the control range ofthe variable pump.
The variable pump only supplies as much hydraulic fluid as
isrequired bythe consumers. If the working pressure
exceeds the pressure command value at the pressure valve,
the pump will regulate toasmaller displacement toreduce
the control differential.

DRS0/DNSO – Pressure controller with load-sensing
Inaddition tothe pressure controller function (DR), the
load-sensing controller works as load pressure guided flow
controller and adjusts the displacement ofthe pump tothe
quantity required by the consumer. The load-sensing
controller compares the pressure upstream the metering
orifice tothe one downstream the orifice and keeps the
pressure drop (differential pressure ∆p) occurring here and
thus the flow constant.
The swinging in by the pressure or the flow controller
always takes priority.

D3/D4 – Pressure controller with override
With the electric pressure adjustment with proportional
solenoid, the high pressure can be continuously set
depending on the solenoid current. If the load pressure
atthe consumer changes, the delivery rate ofthe pump
isadjusted so that the specified pressure is reached again.
Ifthe solenoid current falls below the beginning ofcontrol,
the unit will switch tothe set maximum pressure. The same
is true if the pilot signal is lost.
