| Description |
Sequence 32
Nominal pressure 400 bar
Peak force 450
Control gadget: NV, HD3, HW, DG, DA1, DA2, EP3, EP4, EZ1, EZ2
The A4VG axial piston variable pump in swash plate layout for hydrostatic shut circuit transmissions
– Flow is proportional to travel pace and displacement and is infinitely variable
– Output flow raises with the swivel angle of the swash plate from to its optimum price
– Circulation route modifications easily when the swash plate is moved by way of the neutral place
– A extensive range of very adaptable handle devices is obtainable for diverse management and regulating capabilities
– The pump is outfitted with two strain-aid valves on the substantial strain ports to shield the hydrostatic transmission (pump and motor) from overload
– The large-force aid valves also purpose as improve valves
– The built-in increase pump functions as a feed and control oil pump
– The greatest increase strain is minimal by a developed-in increase force aid valve
– The integral strain minimize-off is regular
