Product Description
QX Series High-Performance Silent Internal Gear Pumps
Product Overview: The QX Series serves as the definitive powerhouse for industrial high-pressure hydraulic systems, excelling in environments that demand ultimate silence, high reliability, and an extended service life. Utilizing the “straight conjugate” internal meshing principle, this series covers a versatile range from single pumps to multi-stage combinations, including models QX52-040R, QX62-125R, QX81-315R, as well as complex configurations like QX41-04031-025R and the double-pump QX21-016/23-006R. Renowned for its near-zero flow pulsation, the QX series is the ideal power source for servo-driven systems and precision machinery requiring high efficiency and energy savings.
Key Technical Advantages:
Ultimate Silence & Low Pulsation: The specialized internal meshing geometry drastically reduces operational noise and ensures minimal pressure ripples. This enhances system stability and significantly improves the surface precision of finished parts.
Non-Contact Gap Compensation: Unique non-contact compensation technology minimizes internal friction and wear. It maintains a superior volumetric efficiency above 95% even during prolonged high-pressure cycles.
Optimized for Servo Drive Systems: Exceptionally low-speed, high-pressure characteristics allow for stable pressure output at near-zero RPMs, synchronizing perfectly with servo motor dynamics for maximum energy efficiency.
Multi-Stage Flexibility: Supports multi-pump combinations (e.g., QX41 or QX21 double-pump series), enabling independent oil sources from a single drive shaft to optimize system layout.
Target Applications: Servo injection molding machines, CNC bending machines, brick presses, lifting platforms, aerospace test benches, and various industrial presses.
