Product Description
GPA Series High-Performance Silent Internal Gear Pumps
Product Overview: The GPA Series is engineered as the “Silent Heart” for precision hydraulic systems. As a premium internal gear pump, the GPA series is the preferred choice for servo-driven injection molding machines, CNC machine tools, and automated production lines due to its exceptional low-noise performance and extreme pressure stability. This featured range includes the GPA1, GPA2, and GPA3 frames, highlighting the core model GPA3-63-E-20-R6.3 and a full displacement spectrum from 1cc to 63cc. Its “straight conjugate” internal meshing technology ensures superior response speed and energy efficiency when paired with variable-speed servo drives.
Key Technical Advantages:
Ultimate Silence & Low Pulsation: Utilizing the internal meshing principle, operational noise is 15-20 dB lower than conventional pumps. Minimal pressure ripples drastically enhance the repeatability of precision molded or machined parts.
Dual Pressure Compensation: Equipped with automated axial and radial pressure compensation mechanisms, maintaining volumetric efficiency above 95% throughout its service life, effectively reducing oil overheating.
Optimized for Servo Drives: Exceptional low-speed, high-pressure characteristics allow for stable pressure output at minimal RPMs, synchronizing perfectly with servo motor dynamics for maximum energy savings.
High Pressure & Longevity: Built with high-tensile materials and hardened gears, with rated pressures up to 16-20 MPa and high peak load capacity.
Target Applications: Servo injection molding machines, CNC bending machines, automated hydraulic power units, footwear machinery, and precision presses.
Detailed Models & Parameters:
Core Series: GPA1, GPA2, GPA3 Internal Gear Pump Series.
