The LH30VO medium-pressure pump was developed
for the open circuit in mobile applications.
The axial piston pump has a swashplate design and can
be operated with through drive up to 130%. They can be
used for a large variety of applications in mobile hydrau-
lics that have requirements that exceed the standard se-
tup on the market.
They are designed for the most common applications,
such as drive equipment, ventilation or steering.
Other regulators are being added – a proportional volu-
me regulator (VE) and a high-performance regulator D
N
are planned. D
N
The Axial piston pump not only comes with a modern
design, but optimised driving gear as well. The increa-
sed performance and the optimised production and as-
sembly processes make the LH30VO an attractive and
high-performing product for agricultural and forestry
equipment, as well as for other mobile applications.

2.4 Shaft lip seal
2.4.1 General information
The rotary shaft lip seals (RWDR) are special sealing elements which permit a specific housing pressure. To ensure
that the tribological system functions optimally, the operating conditions must be complied with.
Sealing edge temperature varies due to the following factors in the housing:
- Circumferential speed
- Hydraulic fluid temperature
- Lubricating medium
- Pressure build-up
The sealing edge temperature may be around 20 °C to 40 °C above the leakage oil temperature of a hydraulic axial
piston unit.
2.4.2 Temperature range
The FKM rotary shaft lip seal is permitted for leakage oil temperatures from -25 °C to +115 °C.
For applications under -25 °C: Consult with Liebherr.

- DA function / pressure cut-off, See chapter 3.3.2
- DE5 function, rising characteristic/pressure cut-off, See chapter 3.3.3
- DE6 function, falling characteristic/pressure cut-off, See chapter 3.3.4
3.3.1 LS0 function
Characteristic
The dynamic characteristics of the control system of variable axial piston pumps can be further improved by load
sensing systems, such as the LS0DA regulator. The LS0 function is designed as a so-called load pressure reporting
system that adapts the volume flow to the current requirements of one or more consumers. It reduces loss of per-
formance compared to regulator functions that convey at maximum volume with lower required volume flow.
The pressure differential Δp between the highest LS pressure in the system (controlled via shuttle valves for multiple
consumers) and the high pressure pHD is compared at an external adjustable measuring orifice and kept in balance
by the pressure compensator (LS axis), which adjust to the demand from the consumers. The LS pressure depends
on the spring force and can therefore be adjusted.
If there is no demand from consumers, the axial piston unit adjusts in direction V
g
min,
until the value is equal to the
set LS pressure. Δp = approx. 14-25 bar, depending on requirement.
If the demand from consumers increases (rising Δp at the orifice), the axial piston unit adjusts in direction V
g
max,
until the working pressure pHD is equal to the sum of the demand-dependent LS pressure + Δp.

3.3.2 DA function
The DA pressure regulator limits the maximum high pressure of the axial piston unit in the regulator range. When a
set high pressure value pHD is reached, the axial piston unit swivels in direction V
g min
and the hydraulic system is
protected against damage and overloading. It continues to swivel in direction V
g min
, until the generated flow equals
the set high pressure value pHD.
If the system pressure falls below the fixed high-pressure value pHD, the axial piston unit swivels to V
g max
.
3.3.3 DE function, rising characteristic (DE5)
The DE function is an electronic pressure regulator, the pressure level for which can be set infinitely variably by a
specified, variable magnet current at the proportional magnet.
The pump is kept at V
g
max
by a spring. The high pressure is passed to a proportional pressure limiting valve via a
pressure compensator (to a pressure limiting valve). When the opening pressure is reached, the pressure limiting
valve of the pump switches and the high pressure swivels the pump in direction V
g
min,
until the pressure in the sys-
tem is once again below the set value for the proportional pressure limiting valve.
The axial piston unit swivels in direction V
g
min
as soon as the magnet current of the proportional magnet is reduced
or stop altogether.

3.3.4 -DE function, falling characteristic (DE6)
The DE function is an electronic pressure regulator, the pressure level for which can be set infinitely variably by a
specified, variable magnet current at the proportional magnet.
The pump is kept at V
g
max
by a spring. The high pressure is passed to a proportional pressure limiting valve via a
pressure compensator (to a pressure limiting valve). When the opening pressure is reached, the pressure limiting
valve of the pump switches and the high pressure swivels the pump in direction V
g
min,
until the pressure in the sys-
tem is once again below the set value for the proportional pressure limiting valve.
As a safety feature e.g. for fan drives, the axial piston unit swivels to V
g max
if the magnetic current at the proportional
magnet is not present or is incorrect.

20
The installation variant for the device or system must be coordinated with Liebherr, as well as the installation posi-
tion, at the conceptual design stage of the axial piston unit and must be approved by Liebherr.
The factory values set by Liebherr are only preset values:
• Readjust the settings on the device or on the system if necessary.
• Prevent foaming: Make sure that the lines meet at least 200 mm below the minimum liquid level in the tank in
every installation variant / position.
Design the hydraulic fluid tank so that the hydraulic oil cools off sufficiently during circulation and impurities that
develop during operation settle to the bottom of the tank.
Liebherr distinguishes between three installation variants for axial piston units: A, B and C; as well as six installation
positions: 1-6.
Note
Liebherr recommends:
Lay the leakage oil lines so that they are above the level of the axial piston unit.
Note
Liebherr recommends:
Installation variant: Under-the-tank installation A
Installation position: Horizontal driving shaft, regulator on top
