Details regarding the choice of hydraulic fluid:
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 58 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG46 or VG66; to be selected: VG66. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 110 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
