Whenusing HFB-, HFC-, HFD- or environmentally acceptable hydraulic fluidspossible limitations for the technical data have to be taken intoconsideration. If necessary please consult our technical department(please indicate type of the hydraulic fluid used for your applicationon the order sheet).Operating viscosity rangeIn order to optain optimum efficiency and service life, we recommendthat the operating viscosity (at operating temperature) be selectedfrom within the range opt = opt.

5 Operating viscosity mm2/sreferred to the loop temperature ( closed circuit) or tank temperature(open circuit).Viscosity limitsThe limiting values for viscosity are as follows:sizes min=5 mm2/s, short term at a max. permissible temperature of tmax = 115 C max= 1600 mm2/s, short term on cold start (tmin = -40 C)sizes min= 10 mm2/s, short term at a max. permissible leakage oil temp. of tmax = 90 C max= 1000 mm2/s, short term on cold start (tmin = -25 C)Please note that the max. fluid temperature is also not exceeded incertain areas (for instance bearing area).At temperatures of -25 C up to -40 C special measures may berequired for certain installation positions. Please contact us for furt-her diagramfluid temperature rangetemperature t in Cviscosity in mm2/sNotes on the selection of the hydraulic fluidIn order to select the correct fluid, it is necessary to know the operatingtemperature in the loop ( closed circuit) or the tank temperature (opencircuit) in relation to the ambient hydraulic fluid should be selected so that within the operatingtemperature range, the operating viscosity lies within the optimumrange ( opt) (see shaded section of the selection diagram).

6 Werecommend that the highest possible viscosity range should be chosenin each : At an ambient temperature of X C the operatingtemperature ( closed circuit: loop temperature; open circuit: tanktemperature) is 60 C. Within the operating viscosity range ( opt;shaded area), this corresponds to viscosity ranges VG 46 or VG 68 should be : The leakage oil (case drain oil) temperature is influencedby pressure and Motor speed and is always higher than the circuit ortank temperature. However, at no point in the circuit may thetemperature exceed 115 C for sizes or 90 C for it is not possible to comply with the above conditions because ofextreme operating parameters or high ambient temperatures pleaseconsult finer the filtration the better the achieved purity grade of thepressure fluid and the longer the life of the axial piston unit. To ensurethe functioning of the axial piston unit a minimum purity grade of9 to NAS 163818/15 to ISO/DIS 4406 is very high temperatures of the hydraulic fluid (90 C to max.)
