Product Description
HG Series High-Pressure Internal Gear Pumps for Shear & Bending Machines
Product Overview: The HG Series is the premier power core for high-end hydraulic forming machinery. Utilizing an advanced internal straight-line conjugate gear profile, this series is optimized specifically for the high-frequency and high-pressure demands of Shear Machines and Bending Machines (Press Brakes). This range features core models such as HG1-25-01R-VPC-36 and the heavy-duty HG2-80, HG2-100, HG2-125, and HG2-160-01R-VPC. With superior axial and radial pressure compensation technology, these pumps deliver stable, silent, and high-efficiency power even under extreme continuous conditions of 31.5 MPa.
Key Technical Advantages:
Ultimate Silence & Anti-Vibration: The specialized internal gear design ensures a smooth flow transition with minimal pulsation. Noise levels are significantly lower than external gear pumps, drastically reducing the operational noise of bending machinery.
Dual Automatic Gap Compensation: Equipped with patented radial and axial compensation mechanisms that adjust in real-time to system pressure, maintaining volumetric efficiency above 95% throughout the pump’s lifecycle.
Optimized for Servo Drive Systems: Supports high-pressure holding at ultra-low RPMs, making it the central component for energy-saving servo press brake systems, enhancing the repeat accuracy of bending angles.
Heavy-Duty Structural Engineering: Built with reinforced pump bodies and wear-resistant bearings to withstand the high-frequency load shocks of shearing and bending processes.
Target Applications: CNC Press Brakes (Bending Machines), Hydraulic Shears, Servo Hydraulic Presses, Brick Presses, and heavy-duty metal forming equipment.
