A3HG Series Variable Displacement Piston Pump Single Pump with Through-Drive Shaft ”A3HG” Series Piston Pumps The new Yuken A3HG series variable piston pumps is a result of the enhanced development based on the exceptional performance characteristics, reliability and innate quality of our current existing A3H series pumps. The Yuken A3HG series, now has an improved nominal pressure of 31.5 MPa (315 bar) from 28MPa (280 bar) and a maximum pressure of 35 MPa (350 bar) that is maintaining the high performance of the A3H series. Features • Enhancing Variety of Port Flange Mounting European Standard : Conform to ISO3019-2 N. American Standard : Conform to SAE J744 Both Keyed Shaft and Spline Shaft are available as standard design. • Wide range of Displacements, with superb Volumetric Efficiency Maintaining the high performance of our A3H pumps, the improved A3HG series now offers a nominal pressure of 31.5 MPa (315 bar).With the choice of keyed or splined shaft this pump can be used in a wide range of applications. • Optional Through Drive Inboard and outboard pumps can be the same size, and any pump which has JIS/ISO or SAE mounting can be fitted to the appropriate inboard pump • Control Type Pressure Compensator Type (01), Pilot Pressure Control Type Pressure Compensator (07) Load Sensing Type (14) Displacement & Rotational Speed • Displacement: 16-180 cm3/rev (7 sizes) • Shaft Speed: A3HG16:3600min-1-A3HG180:1800min-1 We have widened the range and now have available pumps not only with JIS mounting but also ISO and SAE variants as standard depending on market needs With a wide flow range, varying from 16 cm3/rev to 180 cm3/rev, optional through drive - allowing, if required, both pumps to be the same size, we can offer a wide displacement with various control possibilities. Applications • Pressing Machine, Pipe-bending machine, Pipe Terminal Processing Machine, Tube Molding Machine, Steel Mill Equipment, Rolling Equipment, Concrete Production Equipment, Compactor, Industrial Machinery Equipment, Industrial Vehicle Launch Schedule • April 2013

Note) It is necessary to add intermediate flange for some size of pumps. Consult Yuken, when require more details.
