Product Description
Voith QX & QXM Series High-Performance Silent Internal Gear Pumps & Motors
Product Overview: The Voith QX Series is the global benchmark for “High-Pressure Silence” in industrial hydraulics. As high-performance internal gear pumps, this series is engineered to meet the extreme pressure stability demands (Rated up to 32 MPa) of servo-drive systems. This featured range includes: high-precision single pump QX23-005R12, tandem double pump QX22-006/22-006R06, heavy-duty spec QX42-020R/BIZ, and the four-quadrant hydraulic motor QXM42-025L108. Its non-symmetrical gear design ensures ultimate durability throughout its entire service life.
Key Technical Advantages:
Ultra-Quiet & Near-Zero Pulsation: Utilizing Voith’s patented internal meshing technology, operational noise is 10-15 dB lower than conventional pumps. Minimal pressure ripples significantly enhance repeatability in injection molding and CNC bending processes.
Dual Gap Compensation: Equipped with automated radial and axial pressure compensation. Even under continuous high-pressure cycles, it maintains a volumetric efficiency above 95%, effectively minimizing oil overheating.
Optimized for Servo Drives: Supports high-pressure output at extremely low speeds (down to 10 RPM). It synchronizes perfectly with servo motor dynamics for maximum energy efficiency.
QXM Four-Quadrant Operation: Models like the QXM42-025 function as both a pump and a motor, supporting energy recovery and bi-directional drive capabilities.
Target Applications: CNC bending machines, precision injection molding machines, hydraulic lift drives, ceramic presses, and aerospace test rigs.
