▶
Avoid using a check valve in the drain line.
Exception: Above-reservoir installation, drive shaft upward.
A check valve in the drain line (cracking pressure 0.5 bar) can prevent the system
from draining through the drain line. Please note the correct flow direction.
▶
To keep noise values low, use elastic elements to isolate all connecting lines from
all vibration-capable components (e.g., reservoir).
▶
Make sure the suction, drain, and return lines flow into the reservoir below the
min. fluid level under all operating conditions. This will prevent air from being
drawn in and foam from forming.
▶
When designing the reservoir, ensure that there is 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 absolute is present
at port S (0.5 bar absolute for cold start) during operation in all installation
positions and installation locations for the axial piston pump, see Fig. 7. See data
sheet for pressure values.

Suction conditions are better in a below-reservoir installation.
