Axial piston pump with with variable displacement volume: DPVG Data sheet
The robust axial piston pumps of series DPVG have been developed especially for use in mobile machinery for tough environmental conditions. The swash plate design with large pivoting angle is ideal for applications that require variable delivery volume. The DPVG basic pump, thanks to a sophisticated modular system, can be combined with any of the various regulators, mounting flanges, and shaft ends. A through-drive is possible, as is the configuration of two DPVG pumps into a multi-circuit pump in tandem design.

Connection “A / B”
Pressure at working port “A” or “B”:
Nominal pressure pN = 450 bar (not fatigue critical) / Maximum pressure pmax = 500 bar (short term)
Note Definition of short term, unless stated otherwise: t < 1s, t total = 3ooBh.

2 Technical data Axial piston variable-displacement pump DPVG 085 to 280 2.3.2 Minimum operating pressure = feed pressure
In order to guarantee sufficient lubrication in the driving gear in all swivel angles during operation, there must be a pressure applied in the operating circuit, for example measured at M1 or M2, at Vg max and Vg min, of at least pHDmin = 20 bar. The values depend on external circumstances, such as the type of hydraulic fluid used or the temperature, and they must be individually calculated for each use. Values upon request.
2.3.3 Housing pressure, leakage-oil pressure
The housing or leakage-oil pressure pL must not exceed the maximum values. For boundary values, See chapter 2.4.3. The number of leakage-oil connections T can vary depending on the application.
2.4 Shaft seal 2.4.1 General
The radial shaft seals (RWDR) from Liebherr are special sealing elements that allow a specific housing pressure. In order to ensure that the tribological system functions optimally, the operating conditions must be observed. See chapter 2.4.3 Depending on the peripheral speed, oil temperature, lubricant, and pressure buildup in the housing, the sealingedge temperature can be approx. 20° to 40°C above the leakage-oil temperature of a hydraulic axial piston unit.
Date: 12/2014 Version: 1.0 ID No.: 11357580

2 Technical data Axial piston variable-displacement pump DPVG 085 to 280 2.4.2 Temperature range
The FKM radial shaft seal is permissible for housing temperatures of -25°C to +115°C. Please consult us in case of use below -25°C. 2.4.3 Permissible pressure load for hydraulic pumps
The service life of the RWDR is influenced by the speed “n” of the axial piston unit and the leakage-oil pressure “pL.” The constant leakage-oil pressure “pL” should not exceed 3 bar abs. for operating temperature. The max. permissible leakage-oil pressure is 6 bar absolute for reduced speed (see diagram). Short-term pressure peaks of max. 10 bar abs. are allowed (t < 0.1 s) in the short term. The more pressure peaks that occur, the shorter the service life of the shaft seal. The pressure in the axial piston unit must always be higher than the outer pressure on the shaft seal. r a b n i . x a m . s b a

2.5 Housing flushing Under various operating conditions, such as a very low flow over a longer period of time, a boundary value increase in temperature could occur in the housing. See chapter 2.7 In this case, the housing must be flushed in such a manner that the “hot” hydraulic fluid is conveyed to an external cooler, cooled there, and fed back into the hydraulic system. The flushing quantity qV in l/min has to be individually set for each nominal value in connection with the application and is the responsibility of the manufacturer of the device or system.

2 Technical data Axial piston variable-displacement pump DPVG 085 to 280 2.7 Hydraulic fluids 2.7.1 General
The selection of the suitable hydraulic fluid is substantially influenced by the expected operating temperature depending on the ambient temperature that is equivalent to the tank temperature. Use the comparative oil values for the s election of the suitable hydraulic fluid. See chapter 2.7.5 2.7.2 Operating limits
Depending on the operating temperature, the appropriate oil must be selected taking into account the viscosity characteristics according to the following conditions: -
Cold start: max. approx. 1600 mm2 /s *)
-
Normal operation: at or above approx. 500 mm2 /s *)
-
Optimal range of application: 16-36 mm2 /s *)
-
At max. leakage-oil temperature, the viscosity must not be below 8 mm2 /s (short term, meaning < 3 min., 7mm2 /s). The shear stability (KRL) has to be observed for multigrade oils.
*) In reference to the tank temperature In addition to the viscosity characteristics, the Liebherr GSP specification ID No. 10465804 must be observed. 2.7.3 Filling quantity
The required filling quantity can be customized; values upon request. Note The hydraulic unit must be filled with oil and bled prior to initialization. This must be inspected during operation and after longer standstills, and it must be repeated as necessary!
2.7.4 Filtering
-
To maintain the specified purity class “21/17/14 according to ISO 4406” under all circumstances, it is necessary to filter the hydraulic fluid. The hydraulic fluid is filtered by means of the device-specific use of oil filters in the hydraulic system. Cleaning and maintenance intervals of the oil filter, with respect to the entire oil circuit, depend on the device usage, and they are to be found in the device-specific operating manual.

Note Only one nominal value is illustrated per regulation type or function, primarily based on the nominal value 280. Special applications and custom-made productions are not listed in this section. Always use the information from the delivered installation drawing or consult with Liebherr.
3.1 Regulation types Applicable to all regulation types: DANGER The spring-guided return in the regulating valve is not a safety device! Impurities in the hydraulic system such as wear or residual contamination from device or system components can result in blockages in undefined places of the various regulator components. Under certain circumstances, machine operator requirements can no longer be realized. The realization of a safety device, such as an Emergency-Off, is the responsibility of the manufacturer of the device or system.

3 Actuation and regulation types Axial piston variable-displacement pump DPVG 085 to 280 3.3 Regulation functions -
SD function / Control-pressure proportional hydraulic displacement, see chapter 3.3.1 DA function / pressure cut-off valve, see chapter 3.3.2 DA1 function / pressure cut-off valve with override, see chapter 3.3.3 TCH function / hydraulically controlled torque regulation with pressure cut-off valve, see chapter 3.3.4 EL function / electro-proportional displacement, see chapter 3.3.5 ELS function / electro-proportional displacement with safety valve, see chapter 3.3.6 TCE function / electrically controlled torque regulation with pressure cut-off valve, see chapter 3.3.7
3.3.1 SD function
The SD regulation is suitable for applications that require a proportionally regulated volumetric flow rate. Characteristic curve Characteristic
When the drive is displaced from Vg min toward Vg max, the pump swivels to a greater displacement volume Vg with increasing SD control pressure at X1 / X2. If X1 / X2 is switched, then the control piston is displaced into the regulator adjusting unit. The deflection leads directly to the swivel yoke / swivel cradle by mechanical transfer through an adjusting lever, to swivel out the swivel yoke / the swivel cradle, countering the spring force of the return spring toward Vg max. If there is a failing, missing, or defective actuation signal to X1 / X2, the pump swivels toward V g min.

3 Actuation and regulation types Axial piston variable-displacement pump DPVG 085 to 280 3.3.2 DA function
The DA pressure regulation provides the minimization or limitation of the volumetric flow rate of the axial piston unit when it reaches a fixed setting for the high-pressure value pHD. By swiveling toward Vg min, the hydraulic system is protected from damage and overload. It is swiveled toward Vg min until the volumetric flow rate of the axial piston unit, at precisely this pressure level, meets the needs of the consumer. The function of the pressure regulator ensures that the pressure in the system remains constant, even with a changing volumetric flow rate. This equalizes all internal and external losses of leakage oil. Setting range XE approx. 30- 400 bar. Options - Additional internal structural design measures for vibration damping should be implemented after consultation. - Pressure cut-off valve with override function: see chapter 3.3.3 3.3.3 DA1 function
In the closed-loop circuit, the override function DA1 corresponds to a two-stage pressure cut-off valve with 2 pressure stages. -
Pressure stage 1, e.g.: 250 bar or Pressure stage 2, e.g.: 400 bar
The DA1 function in the DA axis in the pressure regulator has the purpose of overriding the fixed setting of the DA cut-off pressure of pressure stage 1 (e.g., 250 bar) by means of an externally fed control pressure pY-pT at the connection Y, and consequently increasing the high pressure to the fixed setting of the DA cut-off pressure of pressure stage 2 (e.g., to 400 bar). This makes it suitable for systems or devices that either require a controllable ability to increase torque or are sub ject to multiple use. Examples are the working hydraulics in mobile excavators and their travel hydraulics.

3 Actuation and regulation types Axial piston variable-displacement pump DPVG 085 to 280 3.3.4 TCH function
With the TCH function, the displacement volume V gof the hydraulic pump can be set in several stages that are dependent on the control pressure at X1 / X2 (pst-pT) and proportionate to the high pressure pHD. This r ealizes constant rotating speeds of the slewing ring, with the simultaneous ability to limit the maximum power input.
Block curve
With increasing control pressure at X1 / X2, the hydraulic pump swivels toward Vg max, and with an increasing pressure differential ΔP A-B it swivels toward Vg min. (See diagram) The respective high pressure is fed back to the pilot control valve and counteracts the control signal. When the drive is at a standstill, it is possible to build up the pressure differential ΔP A-B in the system proportionate to the control signal at X1 / X2, e.g., for holding the superstructure when working on a slope. (See block curve) The TCH function is combined with the DA function, see chapter 3.3.2 and it is particularly well suited for slewinggear controls, for instance. 3.3.5 EL function Characteristic
With the EL function, the displacement volume V g of the axial piston unit is displaced proportionally and infinitely variably via a solenoid. The EL function is subordinate to the DA function, meaning that the EL function dependent on the control current is only implemented below the set value for the pressure cut-off.

3 Actuation and regulation types Axial piston variable-displacement pump DPVG 085 to 280 When the drive is displaced from Vg min toward Vg max, the pump swivels to a greater displacement volume Vg with increasing control current= I at the proportional solenoid DRE. If E1 / E2 is switched, then the control piston is displaced into the regulator adjusting unit. The deflection leads directly to the swivel yoke / swivel cradle by mechanical transfer through an adjusting lever, to swivel out the swivel yoke / the swivel cradle, countering the spring force of the return spring toward Vg max. The hydraulic fluid required for this is obtained from the high-pressure pHD. For low high pressure pHD < 30 bar, the connection Fa must be supplied with a feed pressure of approx. 30 bar in order to ensure the displacement. If there is a missing or defective actuation signal, the axial piston unit swivels to V g min. Options - Safety function. see chapter 3.3.6 3.3.6 ELS function
Set point
Proportional solenoid E1/E2
Switch solenoid E3/E4
If the current consumption at the proportional solenoid DRE exceeds a defined value (e.g., 210 mA), then a switch solenoid E3 / E4 is automatically also supplied with voltage and closes a channel against tank pressure pT in the respective stop valve. This operation is repeated with each actuation of the proportional solenoid DRE. In the event of damage to the proportional solenoid (e.g., becoming stuck due to chucking abrasion), the machine operator, by switching off the control current I at E1 / E2, de-energizes the switch solenoid E3 / E4 and opens the channel to the tank pressure pT in the respective stop valve, and the control pressure is decreased. The axial piston unit swivels toward Vg min.

This r ealizes constant rotating speeds of the slewing ring, with the simultaneous ability to limit the maximum power input. Current characteristics Block curve
With increasing control current = I [mA] at the DRE proportional solenoid E1 / E2, the hydraulic pump swivels toward Vg max, and with an increasing pressure differential ΔP A-B it swivels toward Vg min.

4 Installation conditions Axial piston variable-displacement pump DPVG 085 to 280 Depending on the mounting position and installation variant, the gravitational curb weight and housing pressure have to be taken into account along with the effects of displacement and regulation, such that the settings of the device or system may have to be adjusted. The suction and leakage-fluid lines, in all mounting positions, must flow into the tank below the minimum fluid level in order to prevent foam formation. The oil tank must be designed in such a manner that the hydraulic fluid cools sufficiently during circulation and any impurities are deposited on the floor of the tank. Note Liebherr differentiates between two installation variants, A and B, as well as six mounting positions, 1-6, for the axial piston units.
Note Recommended installation variant(s): Below-tank installation A Installation variant(s) to be avoided: None
Note Recommended mounting position(s): Drive shaft horizontal Mounting position(s) to be avoided: None

4 Installation conditions Axial piston variable-displacement pump DPVG 085 to 280 4.1 Installation variants Note The installation variant is only meaningful for application with an integrated feed pump, and it is described in this section. If there is no integrated feed pump in the mounting plate, then the installation variant is irrelevant. Below-tank installation “A”: Axial piston unit is installed below the minimum fluid level of the tank. Above-tank installation “B”: Axial piston unit is installed above the minimum fluid level of the tank.

4 Installation conditions Axial piston variable-displacement pump DPVG 085 to 280 4.2 mounting positions In each of the two installation variants there are six possible mounting positions. As a rule for the DPVG mounting position, it has to be ensured that the crankshaft of the drive motor / the drive of the pump distributor gear is in line with the drive shaft of the DPVG.
ATTENTION An air buffer in the bearing area, particularly for mounting positions 1 and 3, can result in damage to the hydraulic unit. Ensure that the pump housing has been completely filled with pressure fluid and bled, both at initialization and during operations. Regularly inspect the pressure-fluid level in the housing space; reinitialize if necessary.
Note To prevent emptying of the axial piston unit in mounting position 3 and installation variant B, a check valve with an opening pressure of max. 0.5 bar can be installed in the leakage-fluid line after consultation with Liebherr.
