The XB01VSO series of swash-plate-type axial piston variable displacement pumps is primarily used in industrial hydraulic transmission open circuits, especially suitable for high-pressure, heavy-load applications. Flow rate is directly proportional to both drive speed and displacement and can be infinitely variable; multiple control options are available—including pressure control, flow control, and power control—to prevent overload and meet energy-saving requirements. Featuring a through-shaft design, these pumps satisfy diverse requirements of hydraulic systems. They serve as direct replacements for imported Bosch Rexroth A4V series axial piston pumps.
