Product Overview
▔▔The Yuken A3HM Series represents a premium lineup of high-pressure, variable displacement axial piston pumps designed specifically for demanding industrial and mobile applications. Developed by Yuken, a global leader in hydraulics, this series is engineered to deliver high volumetric efficiency, exceptional reliability, and flexible control mechanisms. Featuring an advanced swash-plate design, the A3HM series dynamically adjusts oil displacement to meet the exact demands of the system, reducing power consumption and minimizing heat generation.
Key Advantages
▔▔
- Drastically Compact & Lightweight: Optimized structural design makes it significantly smaller and lighter than conventional standard pumps, making it perfect for space-constrained mobile machinery.
- High Pressure Capacity: Built to handle challenging jobs with a rated continuous pressure of 31.5 MPa and a maximum peak pressure of 35 MPa.
- Superior High-Speed Performance: Capable of operating at exceptional shaft speeds (up to 3,400 r/min for smaller models), which translates into substantial output flow relative to its physical size.
- Standard Thru-Drive Capability: Features a built-in through-drive system that allows a secondary pump of equal displacement to be mounted directly to the rear, enabling multi-circuit operations from a single prime mover.
- Advanced Energy-Saving Controls: Available with pressure compensation, remote pilot control, and load-sensing mechanisms to prevent energy wastage.

Applications
▔▔| Application Sector | Machine Type | Role of A3HM Pump | Key Benefit Realized |
| Mobile & Construction | Excavators, Wheel Loaders, Crane Rigs | Powers primary travel motors, boom cylinders, and heavy steering assemblies. | Compact chassis fits tightly inside small engine bays while coping with high mechanical shocks. |
| Industrial Manufacturing | Hydraulic Presses, Forging Machinery | Supplies steady high-pressure fluid during stamping and clamping stages. | Variable control lowers energy usage during long pressure-holding cycles. |
| Plastic Processing | Injection Molding Machinery | Controls precise screw clamping forces and high-speed material injection strokes. | Fast response time boosts manufacturing output and part precision. |
| Marine Equipment | Deck Winches, Steering Gear, Anchor Windlasses | Drives high-torque hydraulic motors under wet, salty environmental conditions. | Fluororubber (FKM) seals protect the interior against thermal and chemical degradation. |

FAQ
▔▔Q1: What is the main difference between "Pressure Compensator" and "Load Sensing" controls on the A3HM pump?
A1: The Pressure Compensator type (01 Control) automatically cuts back the pump's oil flow to near zero once the system hits a pre-set pressure limit, protecting the machine from overloading. The Load Sensing type (14 Control) is even more advanced; it senses the actual resistance of the moving workload and changes both the pressure and flow to the absolute minimum required to complete the task, maximizing overall fuel or electricity savings.
Q2: Can I couple another hydraulic pump directly behind the Yuken A3HM pump?
A2: Yes, you can. Every standard model in the A3HM series features a "thru-drive" architecture. This means the primary drive shaft extends all the way through the back of the pump body, allowing you to attach a secondary auxiliary pump (even one with the same displacement capacity) to run off the same engine.
