Product Description
GPA Series High-Performance Ultra-Quiet Internal Gear Pumps
Product Overview: The GPA Series is the ideal power source for modern industrial hydraulic systems. As a precision internal gear pump, this range covers GPA1, GPA2, and GPA3 standards, specifically engineered to meet the dual demands of servo-driven injection molding machines and precision machine tools for low noise (ultra-quiet operation) and high pressure (up to 25 MPa). This selection highlights the core model GPA2-16-E-20-R6.3 and full displacement configurations from the compact GPA1 to high-flow GPA3-63. All models utilize radial and axial gap compensation technology to ensure elite volumetric efficiency throughout their service life.
Key Technical Advantages:
Extreme Quietness: Utilizing the internal meshing principle, the operating noise is exceptionally low (typically below 65dB), making it the premier choice for low-noise, green manufacturing environments.
Perfect Servo Compatibility: Optimized for variable-speed servo motor drives, maintaining stable pressure output even at extremely low RPMs for maximum energy savings.
Compact Design: Compared to external gear pumps of the same displacement, the GPA series offers a smaller footprint and shorter axial length, saving significant installation space in hydraulic power units.
Low Pulsation Output: Unique gear geometry minimizes flow ripples, drastically reducing system vibration and protecting downstream servo valves and precision sensors.
100% Plug-and-Play Replacement: Adheres to standard flange and shaft specifications, ensuring seamless compatibility and replacement with mainstream GPA series pumps.
Detailed Models & Parameters:
Core Series: GPA1, GPA2, GPA3 High Pressure Series.
GPA1 Displacements: GPA1-1, 1, 2, 2, 4, 4 cm³/rev.
GPA2 Displacements: GPA2-2, 4, 6, 10, 16 cm³/rev (Featured: GPA2-16-E-20-R6.3).
