The A2FE set plug-in motor with axial tapered piston rotary team of bent-axis layout, for hydrostatic drives in open and closed circuits
-Far-reaching integration in mechanical gearbox thanks to recessed mounting flange positioned in the middle of the case (incredibly area-saving design)
-The output speed is dependent on the movement of the pump and the displacement of the motor.
-The output torque increases with the strain differential amongst the large-pressure and the lower-strain facet.
-Small dimensions.
-Substantial total efficiency.
-Total unit, completely ready-assembled and examined.
-Straightforward to install, just plug into the mechanical gearbox.
-No configuration specs to be observed when installing.

CZPT fluid
Prior to beginning venture plHangCZPT, remember to refer to our information sheets RE 95710 (mineral oil), RE 95711 (environmentally acceptable hydraulic fluids) and RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for detailed data concerning the selection of hydraulic fluid and application circumstances. The plug-in motor A2FE is not suitable for operation with HFA hydraulic fluid. If HFB, HFC or HFD or environmentally acceptable hydraulic fluids are utilized, the limitations with regards to technical info or other seals must be observed.
Information concerning the selection of hydraulic fluid
The correct decision of hydraulic fluid requires information of the running temperature in relation to the ambient temperature: in a shut circuit, the circuit temperature, in an open up circuit, the reservoir temperature. The hydraulic fluid must be picked so that the running viscosity in the working temperature range is within the ideal range (νopt), see shaded location of the assortment diagram. We recommended that the larger viscosity class be selected in every situation. Instance: At an ambient temperature of X °C, an working temperature of 60 °C is established in the circuit. In the the best possible working viscosity range (νopt., shaded spot) this corresponds to the viscosity classes VG 46 or VG 68 to be selected: VG sixty eight.
Note: The circumstance drain temperature, which is afflicted by pressure and speed, can be larger than the circuit temperature or reservoir temperature. At no point of the ingredient might the temperature be greater than a hundred and fifteen °C. The temperature variation specified underneath is to be taken into account when figuring out the viscosity in the bearing. If the above conditions can’t be preserved due to severe running parameters, we advocate the use of a flushing and enhance force valve.
Shaft seal
Permissible pressure loading the support life of the shaft seal is affected by the velocity of the axial piston unit and the circumstance drain pressure (situation pressure). The indicate differential strain of 2 bar between the scenario and the ambient stress could not be enduringly exceeded at regular functioning temperature. For a greater differential strain at reduced speed, see diagram. Momentary force spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.
