Fluids
Hydraulic fluid
The HA10VSO variable displacement pump is suitable for use with mineral oil.
Operating viscosity range
In order to obtain optimum efficiency and service life, we recommend that the operating viscosity (at operating temperature) for both the efficiency and life of the unit, be chosen within the optimum range of
Referred to tank temperature at open circuit.
Viscosity limits
The limiting values for viscosity are as follows:
nmin = 10 mm2/s short term (t ≤ 1 min) at a max. permissible leakage oil temperature of tmax = 90 °C.
nmax = 1000 mm2/sshort term (t ≤ 1min) on cold start
Temperature range (see selection diagram)
tmin = -25 °Ctmax = 90 °C
Selection diagram
Notes on the selection of hydraulic fluid
In order to select the correct fluid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient temperature.
The hydraulic fluid should be selected so that within the operating temperature range, the viscosity is within the optimum range (nopt; see shaded section of the selection diagram). We recommend that the higher viscosity grade is selected in each case.
Example: at an ambient temperature of X °C the operating temperature in the tank is 60 °C. In the optimum viscosity range nopt ( shaded area), this corresponds to viscosity grades VG 46 or VG 68, VG 68 should be selected.
Important: The leakage oil temperature is influ-enced by pressure and speed and is typically higher than the tank temperature. However max. tempera-ture at any point in the system may not exceed 90 °C.
At high temperatures please use FKM seals.
If the above mentioned conditions cannot be kept due to extreme operating parameters or high ambi-ent temperatures, please consult us.
Filtration of fluid
The finer the filtration, the better the achieved cleanliness of the fluid and the longer the life of the axial piston unit. To ensure a reliable functioning of the axial piston unit, a cleanliness has to be equal or better than 20/18/15 acc. to ISO 4406.
If the above cleanliness classes cannot be met please consult us.

The pressure controller serves to maintain a constant pressure in a hydraulic system within the range of the pump. The pump therefore supplies only the amount of hydraulic fluid required by the system. Pressure may be steplessly set at the pilot valve.

DRG - Pressure control, remote
Function and design same as DR.
A pressure relief valve may be externally piped to port X for remote control purposes. However it is not included in the scope of supply with the DRG control.
The differential presssure at the DRG control spool is set as standard to 20 bar and this results in a pilot flow of 0.4 gpm (1,5 L/min). If another setting is required, please state this in clear text.

In addition to the pressure control function, the pump flow may be varied by means of a differential pressure over an orifice or valvespool installed in the service line. The pump flow is equal to the actual required flow by the actuator. The DFR1-valve has no connection between the X port and the tank.

Hydraulic Pumps
Through Drive
The HA10VSO pump can be supplied with through drive in accordance with the type code. The type of through drive is determined by the code numbers (KB3-KB6). If the combination pump is not mount in the factory, the simple type code is sufficient.
Included in this case are: shaft coupler, seals and if necessary an adapter flange.
Combination Pump
By building on further pumps it is possible to obtain independents circuits:
1. If the combination pump consist of 2 HA10VSO an if these are to be supplied assembled then the two ordercodes should be linked by means of a "+" sign.
Ordering example:HA10VSO 71 DR/31 L-PPA12KB3 + HA10VSO 28 DR/31 L-PSA12N00
2. If a gear or radial piston pump is to be factory mounted as a second pump please consult the factory.

Optional installation position. The pump housing must be filled with fluid during commissioning and remain full when operating.
In order to attain the lowest noise level, all connections (suction, pressure, pilot, case drain) must be linked by flex-ible couplings to tank.
Avoid placing a check valve in the case drain line.
This may, however, be permissible in individual cases, after consultation with us.
1. Vertical installation (shaft end upwards)Following installation conditions must be taken into ac-count:
1.1 Arrangement inside the reservoir.
Before installation fill pump housing, keeping it in a hori-zontal position.
a) If the min. fluid level is equal to or above the pump mounting surface:Close port “L“, "L1" and “S” open; L1 piped and also S with suction pipe (see fig. 1).
b) If the min. fluid level is below the pump mounting surface:pipe port “L“ and “S“ acc. to fig. 2, close port “L“ (compare

2. Horizontal installation
The pump must be installed in such a manner, that either “L“ or “L1“ is at the top.
2.1 Arrangement inside the reservoir
a) If the min. fluid level is above the top of the pump:
Close “L1” , "L" and “S” open, mount suction pipe to port S,and pipe “L“ at least 200 mm away from suction pipe.(see. fig. 3)
b)If the min. fluid level is equal to or below the top of the pump:
Pipe port "L" and "S" acc.to.fig. 4 , port "L1" closed.(compare limiting conditions)
Note: In order to avoid damages to the pump, all attached
item limiting conditions)Note: In order to avoid demages to the pump, all attached parts (e.g. protective caps, covers, etc.) must be removed before installation.
1.2 Arrangement outside the reservoir
Before installation fill pump housing while keeping it in a horizontal position. For mounting above the tank see fig. 2.
Limiting condition:Min. pump inlet pressure Pabs min = 0,8 bar under static and dynamic loading.
Note: Avoid mounting above tank wherever possible in order to attain a low noise level.
The permissible suction height h is a result of the overall pressure loss, but may not be greater than hmax = 800mm
