Sumitomo QT42-20F-Z Hydraulic Pump

Sumitomo QT42-20F-Z hydraulic pump is a high-performance internal gear pump manufactured by Sumitomo Precision Products, engineered for stable operation of industrial hydraulic systems. Drawing on Sumitomo’s century-long precision manufacturing expertise, this pump features ultra-low noise, minimal pressure pulsation and exceptional durability as its core strengths, suitable for high-pressure hydraulic applications across diverse working scenarios.

Sumitomo QT series hydraulic pumps adopt a special internal meshing gear profile and forced lubrication structure, delivering extremely quiet operation with consistent noise levels under varying pressure and rotational speed conditions, greatly improving workshop working environments. With superior pressure pulsation suppression, it supplies steady fluid flow for precision equipment such as machine tools and injection molding machines, ensuring accurate speed control and vibration-free operation. In addition, non-direct contact between sliding components drastically reduces wear, and compatibility with various hydraulic oils enables consistent performance under harsh operating conditions, cutting downtime maintenance and boosting overall equipment efficiency.

Sumitomo QT42-20F-Z hydraulic pump is widely deployed on industrial machinery including injection molding machines, hydraulic presses, forging presses, die-casting machines and CNC machining centers. It serves as an optimal hydraulic component choice for systems requiring low noise, stable performance and long service life, helping enterprises achieve efficient and reliable industrial production.
