▶
When designing the reservoir, ensure that there is an adequate distance between
the suction line and the drain line. This prevents the heated return flow from
being drawn directly back into the suction line.
▶
Make sure that a minimum suction pressure of 0.8 bar abs.
(without charge pump) and/or 0.6 bar abs. (with charge pump) is present
at port

during operation, in all installation positions and installation locations
for the axial piston pump, see Fig. 8. For additional pressure levels see.

The suction conditions improve with below- and inside-reservoir installation.
▶
Make sure that the working environment at the installation site is completely
free of dust and foreign substances. The axial piston unit should be clean
when installed. Contamination of the hydraulic fluid can considerably affect
the function and service life of the axial piston unit.
▶
Use fiber-free cleaning cloths for cleaning.
▶
Use suitable, mild cleaning agents to remove lubricants and other heavy
contamination. Do not allow cleaning agents to enter into the hydraulic system.
7.3 Installation position
The axial piston unit can be installed in the following positions. The pipeline routing
shown illustrates the basic layout.
