7.3.3 Above-reservoir installation
Above-reservoir installation means that the axial piston unit isinstalled above the
minimum fluid level ofthereservoir.
To prevent the axial piston unit from draining, aheight difference h
ESmin
ofat least
25mm atport T
2
isrequired ininstallation position7.
Observe the maximum permissible suction heighth
Smax
= 800mm.
Thepermissible suction heighth
S
isderived from the total pressure loss.
