Fluid

Prior to project design, please see our data sheets RE 90220 (mineral oil ) and RE 90221 (ecologically acceptable fluids) for detailed information on fluids and application conditions. When using ecologically acceptable fluids attention must be paid to possible limitations of the technical data.

Notes on the selection of hydraulic fluid

In order to select the correct fluid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient temperature. The hydraulic fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range (νopt.); see shaded section of the selection diagram. We recommend that the higher viscosity grade is selected in each case. Example: at an ambient temperature of X°C the operating temperature in the tank is 60 °C. In the optimum viscosity range νopt (shaded area), this corresponds to viscosity grades VG 46 or VG 68, VG 68 should be selected. Important: The leakage oil  temperature is influenced by pressure and speed and is typically higher than the tank temperature. However max. temperature at any point in the system may not exceed 115 °C. At high temperatures please use FKM seals.

DG - two point, direct control

The pump can be set to a minimum swivel angle by connecting an external switching pressure to port X. This will supply the control piston directly with control oil; a minimum pressure of 50 bar is required.

DR - Pressure control 

The pressure control serves to maintain a constant pressure in the hydraulic system, within the control range of the pump. The pump therefore supplies only the amount of hydraulic fluid required by the actuators. Pressure can be steplessly set at the pilot valve.
