Working pressure range
Pressure at working port A or B Definition
Nominal pressure p nom 400 bar The nominal pressure corresponds to the maximum design pressure.
Maximum pressure p max 450 bar The maximum pressure corresponds to the maximum working pressure within
a single operating period. The sum of single operating periods must not exceed
the total operating period.
Maximum single operating period 10 s
Total operating period 300 h
Minimum pressure (low-pressure side) 10 bar above
case pressure
Minimum pressure on the low-pressure side (A or B) required to prevent damage
to the axial piston unit.
Boost pressure setting must be higher depending on system.
Rate of pressure change R A max 9000 bar/s Maximum permissible speed of pressure build-up and reduction during
a pressure change across the entire pressure range.
Boost pump
Nominal pressure p Sp nom 25 bar
Maximum pressure p Sp max 40 bar
Pressure at suction port S (inlet)
Continuous p S min ≥0.8 bar absolute ν ≤ 30 mm 2 /s
Short-term, at a cold start ≥0.5 bar absolute t < 3 min
Maximum pressure p S max ≤5 bar absolute
