Detailed Product Description
Variable Piston Pump A7V Series
Description
Variable displacement pump, axial piston, bent axis design, for hydrostatic
transmissions in open circuits.
The flowis proportional to the drive speed and the displacement and is steplessly
variable at constant drive speed.
comprehensive programme of control devices for every control and regulation
function.
operation of both mineral, and fire-resistant fluids.
Special Features
High performance rotary group with well-proven spherical control
area offering the following advantages;self-centering,low peripheral
speed,high efficiency.
Long service life robust rolling bearing.
Drive shaft will support radial loads.
Low noise level.
High duty roller bearing for intermittent high pressure operation.
For continuous duty hydrostatic are available.
