Product Description
GPA Series Low Noise High-Performance Internal Hydraulic Gear Pumps
Product Overview: The GPA Series is an ultra-efficient power component specifically engineered for applications with stringent noise control requirements. As a precision internal gear pump, this series is renowned for its compact architecture, minimal pulsation, and extended service life. This featured range highlights core specifications: GPA1-1-2-EK1-20-R and the high-performance model GPA1-4-E-20-R6.3. Its unique straight-line conjugate gear profile ensures smooth axial fluid delivery, completely eliminating the fluid trapping and noise issues common in traditional external gear pumps, making it the ideal choice for small-scale hydraulic systems and servo-driven units.
Key Technical Advantages:
Ultimate Silent Design: The specialized internal meshing structure keeps operational noise typically below 50-60 dB, maintaining ultra-quiet performance even at high RPMs to drastically improve the work environment.
Minimal Flow Pulsation: High-precision internal gear meshing delivers continuous, nearly ripple-free flow, enhancing the positioning accuracy of hydraulic actuators.
High Efficiency & Energy Saving: Features axial and radial pressure compensation that maintains volumetric efficiency above 95% across the entire operating range, effectively reducing system heat generation.
Compact & Lightweight Construction: The small footprint allows for easy integration into space-constrained hydraulic power units or mobile lifting equipment.
Target Applications: Small lifting platforms, precision CNC machine lubrication, medical device hydraulic drives, laboratory test benches, and servo-hydraulic stations.
