Product Description

QX Series High-Performance Silent Internal Gear Pumps

Product Overview: The QX Series serves as the powerhouse for industrial high-pressure hydraulic systems, excelling in environments that demand ultimate silence and pressure stability. Utilizing the “straight conjugate” internal meshing principle, this series covers critical models including QX53-040R238, QX42-025 R, and QX43-025 R. Renowned for its near-zero flow pulsation, the QX series is widely used in servo-driven injection molding machines, high-precision machine tools, and road roller travel systems. Its unique structural design ensures a service life of tens of thousands of hours even under extreme pressure.

Key Technical Advantages:

  • Ultimate Silence & Low Pulsation: The internal meshing principle reduces operational noise by 15-20 dB compared to conventional pumps. Minimal flow ripples significantly reduce system vibration, enhancing the surface precision of molded parts.

  • Single-Stage High Pressure: Specifically engineered for heavy-duty cycles with a rated working pressure of 25 MPa (250 Bar) and peak capabilities up to 31.5 MPa (315 Bar).

  • Optimized for Servo Drive Systems: Exceptional low-speed, high-pressure characteristics support frequent start-stop and variable speed operation of servo motors, drastically improving overall energy efficiency.

  • High Reliability & Contamination Resilience: Features non-contact gap compensation technology, drastically reducing mechanical wear and maintaining stable volumetric efficiency even in less-than-ideal oil cleanliness conditions.

  • Target Applications: Servo injection molding machines, bending machines, brick presses, road roller travel/vibration circuits, and aerospace test benches.

Detailed Models & Parameters:

  • Core Series: QX High Pressure Internal Gear Pump Series.

  • Model Keywords: QX53-040R238, QX42-025 R, QX43-025 R, QX42, QX43, QX53.

  • Displacements (cm³/rev): Including precise specs: 25cc and 40cc.

  • Pressure Ratings: Rated at 25 MPa (250 Bar / 3625 PSI); Peak pressure up to 31.5 MPa.

  • Rotation & Configuration: R (Clockwise); specialized codes like 238 define specific mounting flanges and porting protocols.
