Note

The values in the table are theoretical values, without consideration of efficiencies and tolerances. The values are rounded. Exceeding the maximum or falling below the minimum permissible values can lead to a loss of function, a reduction in operational service life or total destruction of the axial piston unit. We recommend testing the loads by means of experiment or calculation / simulation and comparison with the permissible values.

Hydraulic fluids

The axial piston unit is designed for operation with mineral oil HLP according to DIN 51524.

Application instructions and requirements for hydraulic fluids should be taken from the following data sheets before the start of project planning:

90220: Hydraulic fluids based on mineral oils and related hydrocarbons 90221: Environmentally acceptable hydraulic fluids

For operation with environmentally acceptable fluids please consult us.

2)	Special version, please contact us.
3)	Equates e.g. with the VG 46 a temperature range of +5 °C to +85 °C (see selection diagram)

Explanatory note regarding the selection of hydraulic fluid

The hydraulic fluid should be selected such that the operating viscosity in the operating temperature range is within the optimum range (vopt see selection diagram).

Selection diagram

Filtration of the hydraulic fluid

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

A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.

At a hydraulic fluid viscosity of less than 10 mm²/s (e.g. due to high temperatures in short-term operation) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.

For example, the viscosity is 10 mm²/s at:

HLP 32 a temperature of 73°C HLP 46 a temperature of 85°C

Total operating period		300 h
Minimum pressure (high-pressure side)	pHP min	10 bar	Minimum pressure on high- or low-pressure side (port A or B) required to prevent damage to the axial piston unit.
Minimum pressure (low-pressure side)	pLP min	see diagram "Permissible rotational speed in relation to outlet pressure"
Rate of pressure change			Definition
Rate of pressure change	RA max	16000 bar/s	Maximum permissible rate of pressure build-up and reduction during a pressure change over the entire pressure range.
