Ordering sample: A7V55-LV-2.0-L-Z-F-OO
Axial piston variable displacement pump A7V, series55,
with constant horsepower control, series 2.0
anti-clockwise rotation, splined shaft SAE side flange
connections, without auxiliary equipment.
    
Variable displacement pump, axial piston bent axis design, for hydrostatic transmissions in open circuits. The flow is proportional to the drive speed and the displacement and is steplessly variable at constant drive speed. Comprehensive program of control devices for every control and regulating function. Simplified high performance rotary group with enhanced technical data and  well-proven spherical control area. Robust roller bearings for high loads. Hydrostatic unloading of bearings possible for ontinuous. pressures up to 400 bar. Operation on both mineral and fire-resistant fluids. Improved port plate design and compact construction reduces noise level by 5 dBA

Hydraulic fluid
For extensive information on the selection of hydraulic fluids and application conditions please consult our data sheets RE 90220 (mineral oils), RE 90221 (ecologically acceptable fluids) and RE 90223 (HF-fluids).
The variable pump A7V is not suitable for operation on HFA fluids. When operating on HFD or ecologically acceptable fluids, limitations to the technical data and seals according to RE 90223 and RE 90221 must be observed.
Notes on the selection of hydraulic fluids
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 in 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 grades VG 46 or VG 68; select: VG 68.
