Yuken A56 Series Pump | A56-F-R-04-H-K-32393 | A37, A56 | Injection Molding Machine Hydraulic Pump

Yuken A56 Series High-Pressure Variable Pump for Injection Molding Machines

Product Overview: The Yuken A56 series axial piston variable displacement pump is a global power benchmark for injection molding machinery hydraulic systems. Renowned for its superior energy efficiency and ultra-low noise levels, this series is widely utilized in precision injection molders, die-casting machines, and heavy-duty industrial presses. Featured models like the A56-F-R-04-H-K-32393 and the A37/A56 lineup utilize highly sensitive pressure compensation (04 Control) to maintain system pressure while drastically cutting reactive power loss, making them critical for optimizing machine OEE.

Key Technical Advantages:

• Superior Energy Saving: The 04 Pressure Compensation mechanism instantly minimizes flow upon reaching the cut-off pressure, preventing hydraulic oil overheating and reducing energy consumption by over 30%.

• Exceptional Low-Noise Performance: Utilizing Yuken’s patented valve plate damping and high-rigidity housings (e.g., K-32393 specs) to maintain minimal noise levels even at full operating pressures.

• High-Response Servo Characteristics: Optimized for the repetitive cycles of injection molding (clamping, injection, holding), providing millisecond-level response for smooth, shock-free transitions.

• Heavy-Duty Long-Life Build: Critical rotating groups (pistons and cylinders) are manufactured from induction-hardened alloys to withstand 24/7 high-intensity production demands.

• 100% OEM Standard Compatibility: Manufactured to strict Yuken factory mounting standards (e.g., series codes 32366, 32393), ensuring flanges, shafts (keyed/splined), and porting match original equipment perfectly.
