Conforms to Global Standards!A3HG Series High Pressure Variable Piston PumpsAdvancing into global markets


  • Feature1:Conforms to International Standards

    Conforms to JIS standards as well the EU's ISO 3019-2 and North America's SAE J744 standards for installation compatibility with pumps used around the world. Key and spline coupling are available as standard for axial ends.
  • Feature2:High Pressure and Displacement Capacity Range

    Rated pressure increased to 31.5 MPa while maintaining the high performance of the A3H Series. A broad range of displacement capacities are also available, ranging from 16 to 180 cm3/rev, for compatibility with a wide range of medium-high load capacity pump applications.
  • Feature3:The standard configuration features through-drive

    The standard configuration features through-drive to allow connection to drive-side and driven-side pumps up to the same capacity, expanding the maximum flow range. Any pumps conforming to international standards can be used on the driven side, simplifying replacement on the machinery.
  • Feature4:Varied Control Methods

    Pressure compensator control, external pilot method pressure compensator control, and load sensing control are all available, for compatibility with any function.
