3. For the version wit through drive, first remove the spacer (4), see chapter 7.4.7
“Remove the spacer (for version with through drive)” on page 34 and fit
the auxiliary pump in accordance with the pump manufacturer’s instructions.
The protective cover(3) is not pressure-resistant and thus not permissible in
operation.
7.4.9 Hydraulically connecting the axial piston unit
NOTICE
Insufficient suction pressure!
Generally, a minimum permissible suction pressure at port S is specified for axial
piston pumps in all installation positions. If the pressure at port S drops below the
specified values, damage may occur which may lead to the axial piston pump being
damaged beyond repair.
▶ Make sure that the necessary suction pressure is met at all times. This is
influenced by:
– The piping (for example, suction cross-section, pipe diameter, length of
suction line)
– The position of the reservoir
– The viscosity of the hydraulic fluid
– Any filter element or check valve in the suction line (regularly check the filter
element’s level of contamination)
The machine/system manufacturer is responsible for sizing the lines. Connect the
axial piston unit to the rest of the hydraulic system in accordance with the hydraulic
circuit diagram of the machine/system manufacturer.
The ports and fastening threads are designed for the maximum permissible
pressures p
max
, see Table 11 “Ports of A10VO, A10VSO and A10VSNO Series 32” on
page 38. The machine/system manufacturer should make sure the connecting
elements and lines correspond to the specified application conditions (pressure,
flow, hydraulic fluid, temperature) with the necessary safety factors.
Connect only hydraulic lines that are match the axial piston unit port (pressure
level, size, system of units).
Observe the following information when routing the suction, pressure and drain
lines.
• Lines and hoses should be installed without pre-charge pressure so no further
mechanical forces are applied during operation that will reduce the service life of
the axial piston unit and, possibly, the entire machine/system.
• Use suitable seals as sealing material.
• Suction line (pipe or hose)
– The suction line should be as short and straight as possible.
