Product Description
QX Series Ultra-High Pressure Internal Gear Pumps
Product Overview: The QX Series represents the pinnacle of internal gear pump technology, renowned for exceptional reliability and an ultra-long service life. This series is engineered for demanding applications requiring extremely high pressures (up to 32 MPa) and minimal operational noise. This range covers the entire spectrum: from compact units QX22-005R, QX21-010/016R70 to medium capacities QX31-025/032, QX41-050R11, and high-flow heavy-duty models QX51-125R and QX61-160R66. Its unique multi-stage meshing principle ensures the ultimate smoothness in fluid delivery.
Key Technical Advantages:
Ultra-High Pressure Resilience: Featuring non-contact gap compensation, it maintains a rated pressure of 32 MPa (320 Bar) with peaks up to 40 MPa, making it the premier choice for high-end servo-driven injection molding systems.
Whisper-Quiet & Low Pulsation: The internal meshing design combined with precision-ground gear profiles reduces noise levels by 15-20 dB compared to external pumps. Minimal pressure ripples significantly extend the life of hydraulic lines and actuators.
Optimized for Servo Drives: Excellent low-speed performance (stable high pressure even at 10-50 RPM) perfectly matches the dynamic response requirements of servo motors for high-precision, energy-saving control.
Versatile Multi-Stage Tandem: Supports multi-stage configurations (double or triple pumps), providing multiple independent pressure sources via a single drive shaft, saving significant installation space.
100% Direct Replacement: Strictly adheres to international SAE or ISO flange and shaft standards, ensuring seamless replacement of existing original Bucher units.
Detailed Models & Parameters:
Core Series: QX2, QX3, QX4, QX5, QX6 High Pressure Series.
Model Keywords: QX31-032, QX31-025, QX21-010, QX22-005R, QX21-016R70, QX41-050R11, QX51-125R, QX61-160R66.
