A10VO
Xeriwell or Others
Rexroth A10VO Axial Piston Variable Pump is designed with variable displacement with axial piston rotary group in swashplate construction for hydrostatic drives in open circuit. It is intended for use in open circuit hydrostatic drives. The swashplate angle can be changed infnitely to vary the drive speed anddisplacement, which are proportional to the pump flow. These pumps have a solid bearing for extended service life and a maximum allowable drive speed.
These pumps are frequently used in equipment for material handling, construction and agriculture that has to operate consistently at a medium pressure. Thesepumps are ideal for heavy-duty applications because of their strong suction qualities, compact size, and low noise level. These pumps are also designed with a robustconstruction for precise operation and a long service life.
Features:
1) Variable axial piston pump in swash plate design for hydrostatic drives in open circuits
2) Flow is proportional to drive speed and displacement. The flow is infinitely variable by adjustment of the swash plate.
3) Strong bearings for long service life
4) High permissible drive speeds
5) High power to weight ratio
6) Small dimensions
7) Low noise level
8) Good suction characteristics
9) Axial and radial loading of drive shaft possible
10) Pressure and flow control
11) Electro-hydraulic pressure control
12) Power control
13) Electro-proportional displacement control
14) Short response times
