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.
