Sumitomo QT Pump | QT62-125F, QT23-6.3F, QT62-80E | Servo Injection Molding Machine Pump

Sumitomo QT Series High-Performance Servo Gear Pumps

Product Overview: The Sumitomo QT Series is the global benchmark for silence and durability in hydraulic systems for Injection Molding Machines (IMM). This selection features core displacements from the compact QT23 to the high-capacity QT62, including models such as QT62-125F-SV-Z, QT23-6.3F-A, QT62-80E-BP-Z, and QT6N-100E-SV-Z. Specifically engineered for servo-variable drive systems, the QT series delivers elite high-pressure stability and ultra-low pulsation. It is the primary choice for precision control and energy reduction in premium IMM brands like Haitian, Chen Hsong, and Yizumi.

Key Technical Advantages:

• Ultra-Low Noise Architecture: Utilizing the unique internal gear principle, it operates with minimal decibel levels, maintaining a mild acoustic profile even during high-pressure holding phases to improve factory environments.

• Low Pulsation & High Precision: Specialized gear profiles drastically reduce flow and pressure ripples, ensuring stable injection speeds and superior part molding accuracy.

• Seamless Servo Integration: Features low rotational inertia, perfectly matching the rapid start-stop, reversal, and high-frequency response requirements of servo motors.

• High-Pressure Longevity: Provides stable rated pressures with minimal internal wear, ensuring an exceptionally long service life under 24/7 high-intensity production cycles.

• Elite Energy Efficiency: Maintains high volumetric efficiency even at low RPMs during holding pressure, effectively reducing system heat and overall energy consumption.
