Details regarding the selection of hydraulic fl uidThe correct selection of hydraulic fl uid requires knowledge of the operating temperature in relation to the ambient temperature, in an open circuit the reservoir temperature.The hydraulic fl uid should be selected so that the operating viscosity in the operating temperature range is within the optimum range (νopt see shaded area of the selection dia-gram). We recommended that the higher viscosity class be selected in each case.Example: At an ambient temperature of X °F (X °C), an operating temperature of 140 °F (60 °C) is set in the cir-cuit. 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.

NoteThe case drain temperature, which is aff ected by pressure and speed, can be higher than the reservoir temperature. At no point of the component may the temperature be higher than 240 °F (115 °C). The temperature diff erence specifi ed below is to be taken into account when determin-ing the viscosity in the bearing.If the above conditions cannot be maintained due to extreme operating parameters, please contact us.

Filtration of the hydraulic fl uidFiner fi ltration improves the cleanliness level of the hydrau-lic fl uid, which increases the service life of the axial piston unit. To ensure the functional reliability of the axial piston unit, a gravimetric analysis of the hydraulic fl uid is necessary to determine the amount of solid contaminant and to deter-mine the cleanliness level according to ISO 4406. A clean-liness level of at least 20/18/15 is to be maintained.At very high hydraulic fl uid temperatures 195 °F to maxi-mum 240 °F (90 °C to maximum 115 °C), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary. If the above classes cannot be achieved, please contact us.

Shaft seal

The FKM shaft seal may be used for case drain tempera-tures from -13 °F to 240 °F (-25 °C to +115 °C).

NoteFor application cases below -13 °F (-25 °C), an NBR shaft seal is required (permissible temperature range -40 °F to +195 °F (-40 °C to +90 °C); ordering code digit 14, K). Please contact us.

Charge pump (impeller)

The charge pump is a circulating pump with which the A15VLO is boosted at the pump inlet and therefore can be operated at higher speeds. This also simplifi es cold starting at low temperatures and high viscosity of the hydraulic fl uid. An external inlet pressure increase is therefore unnec-essary in most cases. Charging the reservoir with com-pressed air is not permissible.

12 A15VSO, A15VLO series 10 | Axial piston variable pumpPower controller

Power controller

LR – Power controller, fi xed settingThe power controller regulates the displacement of the pump depending on the operating pressure so that a given drive power is not exceeded at constant drive speed.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 spool which moves with the control. An externally adjust-able spring force counteracts this, it determines the power setting. The depressurized basic position is Vg max.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 position Vg max toward Vg min. Here, the leverage at the rocker may be shortened and the operating pressure may rise in the same relation as the displacement is reduced (pB • Vg = constant; pB = operating pressure; Vg = displacement).The hydraulic output power (characteristic LR) is infl u-enced by the effi ciency of the pump.Setting range for beginning of control 725 psi (50 bar)1) up to 5100 psi (350 bar).When ordering, state in plain text:

CR – Summation power-control of two power-controlled pumps, high-pressure-related override (with stop)With two pumps of the same size working in diff erent circuits, the CR controller limits the overall power. The CR works like the normal LR with a fi xed 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 beginning 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 fi rst pump is reached when the second pump is working at idle when depressurized. When defi ning 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 pumps are working at high pressure. The minimum power usually equates to 50% of the total power.Power that is released by the pressure control or other overrides remains unconsidered.Setting range for beginning of control 725 psi (50 bar)1) up to 4350 psi (300 bar).When ordering, please state separately for each pump:

PR – Summation power-control of one power-controlled and one fi xed pumpTogether with the mounted fi xed pump, the PR controller on an A15VSO or A15VLO eff ects a limitation of the overall power.The PR works like the normal LR with a fi xed maximum power setting along the power hyperbola. The high-pres-sure-dependent override reduces the power specifi cation in proportion to the operating pressure of the fi xed pump. Here, port PR of the A15VSO or A15VLO must be con-nected to the operating pressure of the fi xed pump. The power of the controlled pump can then be reduced to zero in a borderline case.The maximum power of the controlled pump is reached when the fi xed pump works at idle when depressurized. When defi ning the maximum power, the idle power of the fi xed pump has to be taken into account.Power that is released by the pressure control or other overrides remains unconsidered.Setting range for beginning of control 725 psi (50 bar)1) up to 5100 psi (350 bar)When ordering, state in plain text:

Stroke control

E2 – Stroke control, electric-proportional (positive control)With the electric stroke control with proportional solenoid, the pump displacement is infi nitely variable in proportion to the current by means of magnetic force.Basic position without pilot signal is Vg min. This includes the mechanically depressurized basic position 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 fl uid is taken from the operating pressure or the external control pressure applied to port P.In order for the pump to be moved from the basic position zero or at low operating pressure, port P must be supplied with external control pressure of at least 435 psi (30 bar), maximum 725 psi (50 bar).

NoteIf there is no external control pressure applied to P, the version "Maximum swivel angle (Vg max), without external control pressure supply" must be ordered (see ordering code digit 08, A).

DR – Pressure controller with one-side swiveling, fi xed settingThe pressure controller limits the maximum pressure at the pump outlet within the control range of the variable pump. The variable pump only moves as much hydraulic fl uid as is required by the consumers. If the operating pressure exceeds the setpoint value set at the pressure valve, the pump will regulate to a smaller displacement to reduce the control diff erential.

DRS0 – Pressure controller with load sensingThe load sensing controller works as a load-pressure con-trolled fl ow controller and adjusts the displacement of the pump to the volume required by the consumer.The fl ow of the pump is then dependent on the cross sec-tion of the external measuring orifi ce (1), which is located between the pump and the consumer. Below the setting of the pressure controller and within the control range of the pump, the fl ow is not dependent on the load pressure.As a rule, the measuring orifi ce is a separately located load sensing directional valve (control block). The position of the directional valve piston determines the opening cross section of the measuring orifi ce and thus the fl ow of the pump.The load sensing controller compares pressure before and after the measuring orifi ce and keeps the pressure drop (diff erential pressure Δp) across the orifi ce – and therefore the fl ow – constant.If the diff erential pressure Δp at the measuring orifi ce rises, the pump is swiveled back (toward Vg min). If the diff erential pressure Δp drops, the pump is swiveled out (toward Vg max) until equilibrium at the measuring orifi ce is restored.

ΔpMeasuring orifi ce = pPump – pConsumer

Setting range for Δp 200 psi (14 bar) to 435 psi (30 bar) (please state in plain text)

This means a parallel or synchronous control behavior of several pumps.The DP controller has a fi xed Δp value which is overridden, depending on the swivel angle. Reference operating point is zero stroke.Setting value Δp at zero stroke 490 psi (27 bar).With the externally installed pressure-relief valve (1) the nominal pressure setting of all pumps connected to the system is adjusted to the same value.Setting range from 725 psi (50 bar) to 5100 psi (350 bar).Control fl ow for DP: approx. 0.50 gpm (1.9 l/min) (static) at Δp 490 psi (27 bar).Each pump can be individually unloaded from the system by a separately installed 2/2-way directional valve (2) and set to a standby position.The check valve in the service line (port A) is generally to be provided by the customer. The check valve in the control line (port DP) is included in the scope of supply.The external valves are not included in the scope of supply.As a separate pressure-relief valve (1) we recommend: DBD.6 (manual operation) see data sheet 25402

By using combination pumps, it is possible to have indepen-dent 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 “+”.Order example:A15VSO280LRDRA00/10MRVE4A41SE4A40-0+A15VSO280LRDRA00/10MRVE4A41SU0000-0A tandem pump consisting of two equal sizes is permissible without additional supports assuming that the dynamic mass acceleration does not exceed maximum10 g = 322 ft/s2 = 98.1 m/s2. For combination pumps consisting of more than two pumps, the mounting fl ange must be rated for the permissible mass torque.

Axial piston variable pump | A15VSO, A15VLO series 10 Installation instructions

Installation instructions

GeneralDuring commissioning and operation, the axial piston unit must be fi lled with hydraulic fl uid and air bled. This must also observed following a relatively long standstill as the axial piston unit may drain back to the reservoir via the hydraulic lines.Particularly in the installation position "drive shaft upwards" fi lling and air bleeding must be carried out com-pletely as there is, for example, a danger of dry running.The case drain fl uid in the pump housing must be directed to the reservoir via the highest available drain port (T1, T2, T3).For combinations of multiple units, the case drain fl uid must be drained off at each pump. If a shared reservoir line is used for this purpose, make sure that the case pressure in each pump is not exceeded. In the event of pressure diff erences 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. If this is not possible, separate drain lines must be laid if necessary.To achieve favorable noise values, decouple all connecting lines using elastic elements and avoid above-reservoir installation. In all operating conditions, the suction and drain lines must fl ow into the reservoir below the minimum fl uid level. The permissible suction height hS results from the overall loss of pressure; it must not, however, be higher than hS max = 31.50 in (800 mm). The minimum suction pressure at port S must also not fall below 12 psi (0.8 bar) absolute (without charge pump) or 10.5 psi (0.7 bar) absolute (with charge pump) during operation and during a cold start.When designing the reservoir, ensure adequate space between the suction line and the drain line. This prevents the heated, return fl ow from being drawn directly back into the suction line.

NoteIn certain installation positions, an infl uence on the con-trol characteristics can be expected. Gravity, dead weight and case pressure can cause minor shifts in control char-acteristics and changes in response time.

Installation position See examples 1 to 9 below.Additional installation positions are available upon request.Recommended installation positions: 1 and 2

Below-reservoir installation (standard)Below-reservoir installation means that the axial piston unit is installed outside of the reservoir below the minimum fl uid level.

Above-reservoir installationAbove-reservoir installation means that the axial piston unit is installed above the minimum fl uid level of the reservoir. To prevent the axial piston unit from draining in position 6, the height diff erence hES min at port T2 must be at least 0.98 in (25 mm). Observe the maximum permissible suc-tion height hS max = 31.50 in (800 mm).

Inside-reservoir installationInside-reservoir installation is when the axial piston unit is installed in the reservoir below the minimum fl uid level. The axial piston unit is completely below the hydraulic fl uid.If the minimum fl uid level is equal to or below the upper edge of the pump, see chapter "Above-reservoir installa-tion".Axial piston units with electric components (e.g. electric controls, sensors) must not be installed in a reservoir below the fl uid level.ExceptionInstallation of the pump with E2/E6 control only with HIRSCHMANN connector and if mineral hydraulic fl uids are used and the fl uid temperature in the reservoir does not exceed 176 °F (80 °C)

General instructions

The A15VSO and A15VLO pumps are designed to be used in open circuits.

The project planning, installation and commissioning of the axial piston unit requires the involvement of skilled personnel.

Before using the axial piston unit, please read the cor-responding instruction manual completely and thor-oughly. If necessary, these can be requested from Bosch Rexroth.

During and shortly after operation, there is a risk of burns on the axial piston unit and especially on the solenoids. Take appropriate safety measures (e. g. by wearing protective clothing).

Depending on the operating conditions of the axial piston unit (operating pressure, fl uid temperature), the characteristic may shift.

Service line ports: – The ports and fastening threads are designed for the

specifi ed maximum pressure. The machine or system manufacturer must ensure that the connecting ele-ments and lines correspond to the specifi ed applica-tion conditions (pressure, fl ow, hydraulic fl uid, tem-perature) with the necessary safety factors.

– The service line ports and function ports can only be used to accommodate hydraulic lines.

The data and notes contained herein must be adhered to. Before fi nalizing your design, request a binding installa-

tion drawing.

Not all variants of the product are approved for use in safety functions according to ISO 13849. Please consult the responsible contact person at Bosch Rexroth if you require reliability parameters (e.g. MTTFd) for functional safety.

Pressure controllers are not backups against pressure overload. A separate pressure-relief valve is to be pro-vided in the hydraulic system.

The following tightening torques apply: – Fittings:

Observe the manufacturer's specifi cations regarding the tightening torques of the fi ttings used.

– Mounting bolts:For mounting bolts with metric ISO thread according to DIN 13 or thread according to ASME B1.1, we recommend checking the tightening torque in indi-vidual cases in accordance with VDI 2230.

– Female threads in the axial piston unit:The maximum permissible tightening torques MG max are maximum values for the female threads and must not be exceeded. For values, see the following table.

– Threaded plugs:For the metallic threaded plugs supplied with the axial piston unit, the required tightening torques of threaded plugs MV apply. For values, see the follow-ing table.
