LVP
Variable displacement axial piston pumps with swash plate design. LVP pumps are ideally suited for medium and
high pressure open circuit applications. They are available with a wide range of control options to regulate the pumps
displacement. The drive shaft is designed for both radial and axial loads. The pumps are also available with a through
drive option to have multiple pumps able to supply several hydraulic systems.

GENERAL INFORMATION / INSTRUCTIONS
STORAGE
No problem in case of temperature down to -40ยฐC (-40ยฐF).
Below -40ยฐC (-40ยฐF) please consult our technical-sales de-
partment.
STARTING UP
We strongly recommend to warm up the oil before running the
machine. If this is not possible, the warm up of the oil and of the
pump should be carried out following these instructions:
โข Start the pump in stand-by condition at minimum speed.
Keep this working condition until the pump case reaches
-20ยฐC (-4ยฐF)
โข Increase slowly the displacement.
Max pressure permitted: 50 bar (725 psi). The maximum
permitted speed is strictly connected to the layout of the inlet
circuit; check that there is no cavitation before increasing the
speed.
โข Keep this working condition until the oil temperature in the
whole system is -10ยฐC (14ยฐF).
โข Maximum pressure can be achieved from now on.
โข Always check the outlet flow to prevent cavitation damage.
All the temperature are referred to oil with viscosity ISO VG 32
according to DIN 51 519.
SUGGESTIONS
To prevent cavitation at low temperature we suggest:
โข To warm up the tank
โข To pressurize the tank
โข To oversize the inlet hose
FOR VERY LOW TEMPERATURE
DIRECTION OF ROTATION
Clockwise or anti-clockwise defined looking at the drive shaft.
HYDRAULIC FLUID
Mineral oil based hydraulic fluid conforming to DIN 51524,
fire resistant fluids and biodegradable fluids according to the
technical data shown in the tables at pages 4 รท 6. The system
should be designed to prevent aeration of the hydraulic fluid.
FLUID VISCOSITY
The fluid viscosity range for optimal use of LVP pump is betwe-
en 15 and 35 cSt (77 and 163 SSU).
Functional limit conditions are:
max.: 1500 cSt (6818 SSU) at start up at -25 ยฐC (-13 ยฐF) with
straight and short inlet line.
min.: 10 mm
2
/s (58 SSU) at maximum temperature of 110 ยฐC
(230 ยฐF)
FILTRATION
To ensure the optimal performance and the maximum life to the
pump, the hydraulic fluid must have and maintain a fluid conta-
mination within the values shown in the table below.

Casappa recommends to use its own
production filters:
INSTALLATION
Check that the maximum coupling eccentricity stays within 0,25
mm (0.0098 in) to reduce shaft loads due to misalignment. It is
advised to use a flexible coupling suitable to absorb eventual
rotational shocks. For applications with axial and radial loads
exceeding published standards, consult our sales department.
The direction of rotation of the pump must agree with the prime
mover rotation. Before installation, the case of the pump must
be filled with fluid.
LINES
The lines must have a major diameter which is at least as
large as the diameter of pump ports, and must be perfectly
sealed.
To reduce loss of power, the lines should be as short as possi-
ble, reducing the sources of hydraulic resistance (elbow, thrott-
ling, gate valves, etc.) to a minimum. A length of flexible tubing
is recommended to reduce the transmission of vibrations.
Before connecting the lines, remove any plug and make sure
that the lines are perfectly clean. Check that the drain line is
dimensioned in a way to guarantee a case pressure lower than
1,5 bar (22 psi) absolute. The drain line must be connected
directly (no filter, no valves, no oil cooler) to the tank and must
terminate below the oil level. Check that the dimensions of the
suction line guarantee a pressure equal or superior to 0,8 bar
(24 in Hg). Inlet pressure less than 0,8 bar (24 in Hg) could
cause an increase of noise emission, the decrease of the pump
performances and a reduction of its life expectancy.
STARTING UP
Check that all connections are secure and that the entire sy-
stem is completely clean. Add oil to the tank always using a
filter. Bleed the air from the circuit to help the filling. Turn on the
system for a few moments at minimum speed, then bleed the
circuit again and check the level of oil in the tank. Gradually
increase the pressure and speed of rotation up to the pre-set
operating levels, which must stay within the stated limits as
specified in the catalogue.

MOUNTING POSITIONS
Standard pump is supplied with the D2 drain hole open and D1
plugged.
Before installation fill the pump with hydraulic oil for at least 3/4
of the volume keeping it in horizzontal position.
The pump can be mounted in a horizontal or vertical position.
The highest of the case drain ports must be used to keep the
required filling oil.
If D2 is not the highest drain port it must be closed by moving
the plug from D1 hole chosen for the drain line.
The pump can be located above the oil level if the absolute
pressure at the inlet port stays within the stated limits.
With exception of pump mounted below the oil level, we recom-
mend to interpose a baffle plate between inlet and drain line.
To reduce further noise emission, we recommend to mount the
pump below the oil level and avoid suction lines with sharp re-
strictions.

For lower torque setting values, the regulator limits the maxi-
mum working pressure to a value lower than the standard set-
ting for the pressure regulator 280 bar (4060 psi).
When ordering the torque limiter please specify the requested
value of torque [eg. 70 Nm (620 lbf in)] or the requested power
and speed [eg. 10 kW (13.4 HP) at 1500 min

Damping restrictor for critical applications.
In case of system instability or pressure oscillations, the addi-
tional damping restrictor slows down the pump control system,
damping the regulation transients.
The pump regulation response time increases.
The use of the damping restrictor must be evaluated and ap-
proved by Casappa technical sales department for the specific
application.

DIGITAL INTEGRATED DRIVERS DES..
Digital drivers, integrated to the pump, realize combined closed
loop controls of pressure, flow and maximum power limitation.
These controls provide fast dynamics and fine regulations di-
rectly commanded from PC or from the machine controller.
They are also available with an optional sequence module that
allows the circuit to operate with minimum pressure (close to
zero). A remote pressure transducer must be installed on the
system and its feedback has to be interfaced to the pump digital
driver. If the real pressure value in the system (measured by the
pressure transducer) remains below the respective reference
signal provided by the machine controller, the digital driver re-
gulates in closed loop the pump swash plate position according
to the flow reference signal.
When the real pressure becomes close to the respective refe-
rence signal, the driver automatically perfoms the closed loop
control of the pressure.
The digital control ensures high performance regulating flow
and pressure linearity, better flow knee and internal leakage
compensation.
DES
Basic version, without sequence module and without
pressure transducer which has to be installed on the
outlet line and wired to the 12 poles connectors of the
integral digital electronics.
DESR
Version with sequence module RES which grant a
minimum piloting pressure [18 bar (261 psi)] when the
actual pressure falls below that value.
Without pressure transducer.

The operating characteristics of each assembled pumps are the same as the corresponding single pumps according to the fol-
lowing conditions:
1) Do not exceed the maximum transmissible torque.
2) The maximum rotational speed is that of the lowest rated speed of the single unit incorporated.
