Working pressure range
Working pressure range
Pressure atworking port B Definition
Nominal pressure p
nom
250 bar The nominal pressure corresponds tothe maximum design pressure.
Maximum pressure p
max
280 bar The maximum pressure corresponds tothe maximum working pressure within
asingle operating period. The sum ofthe single operating periods must not
exceed the total operating period (maximum number ofcycles: approx. 1 million).
Single operating period 0,05s
Total operating period 14 h
Minimum pressure p
B abs
(high-pressure side)
14 bar
1)
Minimum pressure onthehigh-pressure side (B) which isrequired inorder
toprevent damage tothe axial piston unit.
Rate ofpressure change R
Amax
16000bar/s Maximum permissible pressure build-up and reduction speed during apressure
change across the entire pressure range.
Pressure atsuction port S (inlet)
Minimum pressure p
Smin
0.8bar abs. Minimum pressure atsuction port S (inlet) which isrequired toprevent damage
tothe axial piston unit. The minimum pressure depends onthe rotational speed
and displacement ofthe axial piston unit.
Maximum pressure p
Smax
5bar abs.

Notice
▶ Working pressure range applies when using
hydraulicfluids based onmineral oils. Please contact
usforvalues forother hydraulic fluids.
▶ Inaddition tothe hydraulic fluid and the temperature,
the service life ofthe shaft seal isinfluenced bythe
rotational speed ofthe axial piston unit and the
casepressure.
▶ The case pressure must not be below the
ambientpressure.
