Hydraulic parameters
Inlet pressure
Minimum pressure, continuous = 0.8 bar absolute [23.2 in Hg]
Minimum pressure, cold start = 0.5 bar absolute [14.8 in Hg] (at reduced maximum pump speed)
Pressure compensator valve setting
Minimum: 100 bar [1450 psi]
Maximum: 260 bar [3770 psi]
Case pressure
Maximum continuous: 0.5 bar [7 psi] Above inlet
Intermittent: 2 bar [29 psi] Cold start
