Product Description
Bucher QX Series High-Pressure Ultra-Quiet Internal Gear Pumps
Product Overview: The Bucher QX Series stands as the global industry benchmark for “Ultra-Quiet” hydraulic power. This featured selection includes core precision models: the high-flow tandem pump QX61-160/63-125R, the mid-range double pump QX41-040/31-025R, and precision single units QX22-005R and QX21-012R112-Y. Engineered with a unique internal gear principle, these pumps are specifically designed to meet the rigorous demands of injection molding machines, die-casting equipment, and servo-driven systems for high pressure, low pulsation, and rapid frequency response. Their non-symmetrical gear profiles ensure unmatched control precision at pressures up to 320 Bar.
Key Technical Advantages:
Ultra-Low Noise Operation: The internal meshing technology delivers decibel levels significantly lower than external gear pumps, perfect for modern “Silent Factory” initiatives.
Integrated Tandem Supply: The QX61/QX41 tandem designs power two independent circuits from a single drive shaft, allowing for high-low pressure combinations and optimizing installation space.
Perfect Servo Compatibility: Specifically optimized for variable-speed drives (VSD), maintaining high-pressure output even at extremely low RPMs or near-stall conditions.
Superior Pulsation Control: Exceptionally low pressure ripples protect downstream servo valves and actuators, significantly enhancing the precision of the final processed products.
100% Plug-and-Play Replacement: Strictly adheres to original Bucher OEM specifications (including specialized 112-Y configurations), ensuring identical flange patterns, shaft ends, and port positions.
