Product Description
QX Series Ultra-Quiet Internal Gear Hydraulic Pumps & Motors
Product Overview: The QX Series represents the pinnacle of internal gear technology, renowned for “Ultra-High Pressure, Extreme Silence, and Long Life.” This comprehensive range features high-end models: the energy-efficient QXEH42-032R451 pump, the high-performance QXEM42-025N motor, and precision double-pump combinations like QX51-125/43-025R, QX52-100/51-100R05, and QX62-100/51-100R05. Its unique three-stage meshing principle ensures exceptional pressure stability and minimal noise even under variable-speed servo-drive conditions.
Key Technical Advantages:
Servo-Optimized QXEH/QXEM Design: Purpose-built for high-frequency servo responses. QXEH pumps maintain high pressure at ultra-low RPMs, while QXEM motors deliver superior starting torque and low-speed smoothness.
Whisper-Quiet & Minimal Pulsation: Utilizing non-contact gap compensation, operational decibels are significantly lower than traditional external pumps. Near-zero pressure ripples drastically extend the life of hydraulic lines and components.
Versatile Multi-Stage Tandem: Supports double-pump configurations (e.g., QX51/43 or QX62/51), allowing a single drive shaft to power two independent circuits, saving significant space and costs.
Heavy-Duty Durability: Constructed with reinforced cast-iron housings and precision-ground gears, rated for continuous pressures up to 32 MPa with peaks reaching 40 MPa, ideal for 24/7 heavy-duty industrial cycles.
100% Direct Replacement: Strictly adheres to SAE/ISO mounting standards, ensuring seamless compatibility with original Bucher-style units.
