Pressure at suction port S (inlet)
Minimum suction pressure pS min _________ 0.8 bar absolute
Maximum suction pressure pS max ________ 30 bar absolute
Minimum pressure (inlet)
In order to avoid damage to the axial piston unit, a minimum
pressure must be ensured at the suction port S (inlet). The mi
nimum pressure is dependent on the speed and displacement
of the axial piston unit.

The inlet pressure is the static feed pressure or the minimum
dynamic value of the boost pressure.

Definition
Nominal pressure pnom
The nominal pressure corresponds to the maximum design
pressure.
Peak pressure pmax
The peak pressure corresponds the maximum operating pres
sure within the single operating period. The sum of the single
operating periods must not exceed the total operating period.
Minimum pressure (high-pressure side)
Minimum pressure on the high-pressure side (B) that is re
quired in order to prevent damage to the axial piston unit.
Rate of pressure change RA
Maximum permissible rate of pressure build-up and pressure
reduction during a pressure change over the entire pressure
range.
