RE 9606/0.97 Fluid We request that before starting a project detailed information about the choice of pressure fluids and application conditions are taken from our catalogue sheets RE 90220 (mineral oil, RE 9022 (environmentally acceptable hydraulic fluids and RE 9022 (fire resistance fluids, HF. When using HF- or environmentally acceptable hydraulic fluids possible limitations for the technical data have to be taken into consideration. If necessary please consult our technical department (please indicate type of the hydraulic fluid used for your application on the order sheet. he operation with HF-, HF- and HFC- hydraulic fluids requires additional special measures. Operating viscosity range In order to obtain optimum efficiency and service life, we recommend that the operating viscosity (at operating temperature be selected from within the range: ν opt = operating viscosity 6...6 mm 2 /s referred to the loop temperature (closed circuit or tank temperature (open circuit. Viscosity limits he limiting values for viscosity are as follows: size 28...60 ν min = mm 2 /s, short term at a max. permissible temperature of t max = C ν max = 600 mm 2 /s, short term on cold start (t min = -40 C size 20 ν min = 0 mm 2 /s short term at a max. permissible leakage oil temp. of t max = 90 C ν max = 000 mm 2 /s, short term on cold start (t min = -2 C In general the max. temperature is the leakage oil temperature of the hydraulic motor in case of hydrostatic transmissions. Please note that the max. fluid temperature is also not exceeded in certain areas (for instance bearing area. t temperatures of -2 C up to -40 C special measures may be required for certain installation positions.

We recommend that the highest possible viscosity range should be chosen in each case. Example: t an ambient temperature of X C the operating temperature is 60 C. Within the operating viscosity range (ν opt ; shaded area, this corresponds to viscosity ranges VG 46 or VG 68. VG 68 should be selected. Important: he leakage oil (case drain oil temperature is influenced by pressure and pump speed and is always higher than the circuit temperature. However, at no point in the circuit may the temperature exceed C (90 C, size 20. If it is not possible to comply with the above conditions because of extreme operating parameters or high ambient temperatures please consult us.
