Product Description
QX Series High-Performance Silent Internal Gear Pumps
Product Overview: The QX Series serves as the powerhouse for industrial high-pressure hydraulic systems, excelling in environments that demand ultimate silence and pressure stability. Utilizing the “straight conjugate” internal meshing principle, this series covers critical models including QX53-040R238, QX42-025 R, and QX43-025 R. Renowned for its near-zero flow pulsation, the QX series is widely used in servo-driven injection molding machines, high-precision machine tools, and road roller travel systems. Its unique structural design ensures a service life of tens of thousands of hours even under extreme pressure.
Key Technical Advantages:
Ultimate Silence & Low Pulsation: The internal meshing principle reduces operational noise by 15-20 dB compared to conventional pumps. Minimal flow ripples significantly reduce system vibration, enhancing the surface precision of molded parts.
Single-Stage High Pressure: Specifically engineered for heavy-duty cycles with a rated working pressure of 25 MPa (250 Bar) and peak capabilities up to 31.5 MPa (315 Bar).
Optimized for Servo Drive Systems: Exceptional low-speed, high-pressure characteristics support frequent start-stop and variable speed operation of servo motors, drastically improving overall energy efficiency.
High Reliability & Contamination Resilience: Features non-contact gap compensation technology, drastically reducing mechanical wear and maintaining stable volumetric efficiency even in less-than-ideal oil cleanliness conditions.
Target Applications: Servo injection molding machines, bending machines, brick presses, road roller travel/vibration circuits, and aerospace test benches.
