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

Operating pressure range

Pressure at working port A or B (high-pressure side)			Definition
Nominal pressure	pnom	see table of values	The nominal pressure corresponds to the maximum design pressure.
Maximum pressure	pmax	see table of values	The maximum pressure corresponds to the maximum operating pressure within the single operating period. The sum of the single operating periods must not exceed the total operating period.
Single operating period		10 s
Total operating period		300 h
Minimum pressure	pHP min	25 bar	Minimum pressure on high-pressure side (port A or B) required to prevent damage to the axial piston unit.
Minimum pressure at inlet (pump operating mode)	pE min	see diagram	To prevent damage to the axial piston motor in pump mode (change of high-pressure side with unchanged direction of rotation, e.g. when braking),a minimum pressure must be guaranteed at the working port (inlet). The minimum pressure depends on the rotational speed and displacement of the axial piston unit.
Total pressure	pSu	700 bar	The summation pressure is the sum of the pressures at both work ports (A and B).
Rate of pressure change			Definition
with integrated pressure relief valve	RA max	9000 bar/s	Maximum permissible rate of pressure build-up and reduction during a pressure change over the entire pressure range.
without pressure relief valve	RA max	16000 bar/s
Case pressure at port T			Definition
Continuous differential pressure	ΔpT cont	2 bar	Maximum averaged differential pressure at the shaft seal (case to ambient)
Pressure peaks	pT peak	10 bar	t < 0.1 s
