Product Overview
The ATOS PFG-120-D (part number 115498408) is a high-performance external gear pump engineered by Atos, a globally recognized manufacturer of precision hydraulic components. Operating on the positive displacement principle, this fixed-displacement gear pump uses two precision-machined intermeshing gears to draw hydraulic fluid from the reservoir and deliver a constant, pulsation-minimized flow to the system. With a nominal displacement of approximately 22.5 cm³/rev belonging to the PFG-120 group, it serves as a reliable pressure source in industrial hydraulic circuits, providing consistent flow for actuation, lubrication, and power transmission duties. Its robust cast-iron construction and optimized gear geometry make it a dependable choice for continuous-duty applications where durability and volumetric efficiency are paramount.
