Technical data Hydraulic fluid

Details regarding the choice of hydraulic fluid

Before starting project planning, please refer to our data sheet RE 90220 (mineral oil) for detailed information regarding the choice of hydraulic fluid and application conditions.

The correct selection of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in an open circuit, the reservoir temperature.

The variable pump A15VSO is currently approved for operation with mineral oil.

The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (νopt see shaded area of the selection diagram). We recommended that the higher viscosity class be selected in each case.

Please contact us about operation with environmentally acceptable or HF hydraulic fluids. Selection diagram -40° 1600 1000 600 400

Example: At an ambient temperature of X °C, an operating temperature of 60° C is set in the circuit. In the optimum operating viscosity range (νopt, shaded area), this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Note The case drain temperature, which is affected by pressure and speed, is always higher than the reservoir temperature. At no point of the component may the temperature be higher than 115 °C, however. The temperature difference specified below is to be taken into account when determining the viscosity in the bearing. If the above conditions cannot be maintained due to extreme operating parameters, please contact us.

Technical data Filtration of the hydraulic fluid

Case drain pressure

Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.

The case drain pressure at ports T1 to T3 may be a maximum of 1.2 bar higher than the inlet pressure at port S but not higher than

To ensure the functional reliability of the axial piston unit, a gravimetric analysis of the hydraulic fluid is necessary to determine the amount of solid contaminant and to determine the cleanliness level according to ISO 4406. A cleanliness level of at least 20/18/15 is to be maintained.

pL max____________________________________ 4 bar absolute.

At very high hydraulic fluid temperatures (90 °C to maximum 115 °C), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary.

A case drain line to the reservoir is required.

Shaft seal Temperature range The FKM shaft seal may be used for case drain temperatures from -25 °C to +115 °C. Note For application cases below -25 °C, an NBR shaft seal is required (permissible temperature range: -40 °C to +90 °C). State NBR shaft seal in plain text when ordering. Please contact us.

Power controller LR - Power controller, fixed setting

The power control regulates the displacement of the pump depending on the operating pressure so that a given drive power is not exceeded at constant drive speed. pB • Vg = constant

Schematic LR

pB = operating pressure Vg = displacement

The precise control with a hyperbolic control characteristic, provides an optimum utilization of available power. The operating pressure acts on a rocker via a measuring piston which moves with the control. An externally adjustable spring force counteracts this, it determines the power setting. The depressurized basic setting is Vg max. MA

A P

Vg min

If the operating pressure exceeds the set spring force, the control valve will be actuated by the rocker and the pump will swivel back from the basic setting Vg max toward Vg min. This shortens the leverage at the rocker, allowing the operating pressure to rise at the same ratio as the displacement is reduced (pB • Vg = fixed). The hydraulic output power (characteristic LR) is influenced by the efficiency of the pump.

Power controller CR – Summation hp-control of two power-controlled pumps, high-pressure-related override (with stop) LR

With two A15VSO units of the same size working in different circuits, the CR controller limits the overall power.

Schematic CR CR

The CR works like the normal LR with a fixed maximum power setting along the power hyperbola. The high-pressure-related override reduces the power setpoint in dependence on the operating pressure of the other pump. That happens proportionally below the start of control and is blocked by a stop when the minimum power is reached. Here, the CR port of the one pump has to be connected to the MA port of the other pump. The maximum power of the first pump is reached when the second pump is working at idle when depressurized. When defining the maximum power, the idle power of the second pump has to be taken into account. The minimum power of each pump is reached when both A P at high pressure. The minimum power MA working pumps are usually equates to 50% of the total power.

Stroke limiter E2 – Stroke limiter, electric, proportional (positive control)

Basic setting without pilot signal is Vg min. This includes the mechanically depressurized basic setting Vg min (see ordering code digit 08). With increasing control current the pump swivels to a higher displacement (from Vg min to Vg max). The necessary control power is taken from the operating pressure or the external control pressure applied to port P.

Characteristic E2 770

Control current I [mA]

With the electrical stroke limiter with proportional solenoid, the pump displacement is steplessly adjusted in proportion to the current by means of magnetic force.

To enable the pump to be adjusted from the zero basic setting or from a low operating pressure, port P must be supplied with an external control pressure1) of at least 30 bar, maximum 50 bar. Note If no external control pressure is connected to P, the version "Maximum swivel angle (Vg max), without external control pressure supply" is to be ordered (see ordering code digit 08, A).

Note The spring return feature in the controller is not a safety device The controller can stick in an undefined position by internal contamination (contaminated hydraulic fluid, abrasion or residual contamination from system components). As a result, the control will no longer respond correctly to the operator's commands. Check whether the application on your machine requires additional safety measures, in order to bring the driven actuator into a controlled and safe position (e. g. immediate stop).

With an external supply of control pressure, it is possible for the pump to swivel slightly beyond the zero position (to the mechanical stop). 2) Because of the controller hysteresis, a control current of up to 650 mA may be required for the Vg max position. 1)

Pressure controller DR - Pressure controller with one-sided deflection, fixed setting L3/4

The pressure controller keeps the pressure in a hydraulic system constant within its control range even with varying volume flow. The variable pump only moves as much hydraulic fluid as is required by the consumers. If the operating pressure exceeds the setpoint value set at the integral pressure valve, the pump control will shift toward a smaller displacement and the control deviation will decrease.

Pressure controller DRS0 - Pressure controller with load sensing

Vg max

The sensing orifice is usually a separately arranged load sensing directional valve (control block). The position of the directional valve piston determines the opening cross section of the sensing orifice and thus the flow of the pump. S MS

T1 T2 T3

The load sensing control compares pressure before and after the sensing orifice and maintains the pressure drop across the orifice (differential pressure ∆p), and with it the flow, constant. If the differential pressure ∆p increases at the sensing orifice, the pump is swiveled back (towards Vg min), and, if the differential pressure ∆p decreases, the pump is swiveled out (towards Vg max) until equilibrium at the sensing orifice is restored. ∆psensing orifice = ppump – pconsumer

By using combination pumps, it is possible to have independent circuits without the need for splitter gearboxes. When ordering combination pumps, the type designations of the 1st and 2nd pumps must be linked by a “+”. Ordering example: A15VSO280LRDRA0V/10MRVE4A41EE4A40-0+ A15VSO280LRDRA0V/10MRVE4A41EU0000-0 A tandem pump consisting of two equal sizes is permissible without additional supports assuming that the dynamic acceleration does not exceed maximum 10 g (= 98.1 m/s2). For combination pumps consisting of more than two pumps, the mounting flange must be rated for the permissible mass torque.

Particularly in the installation position "drive shaft upwards" filling and air bleeding must be carried out completely as there is, for example, a danger of dry running.

For combinations of multiple units, make sure that the respective case pressure in each unit is not exceeded. In the event of pressure differences at the drain ports of the units, the shared drain line must be changed so that the minimum permissible case pressure of all connected units is not exceeded in any situation.
