A4VTG090
Rexroth
Product Overview:
The A4VTG090 is a high-pressure, swashplate design axial piston pump specifically engineered for closed-loop hydraulic systems. Known for its compact structure, high power density, and excellent controllability, this pump is widely used as a direct replacement for original Rexroth units. With a displacement of 90 cc/rev, it delivers reliable and efficient hydraulic power for demanding mobile and industrial applications.
