Atos Gear Pump Product Catalog
Overview
Atos (Atos Hydraulics), an advanced Italian manufacturer of electro-hydraulic components, offers a full range of high-performance gear pumps designed for diverse industrial and mobile hydraulic applications. The product line is mainly categorized into External Gear Pumps (PFG Series) and Modular Combined Gear Pumps (PFG-POX Series). All Atos gear pumps feature simple and robust construction, low noise operation, high efficiency, and reliable performance, widely used in steel, metallurgy, power, injection molding, automotive manufacturing, and other fields.
1. External Gear Pumps (PFG Series)
Atos PFG series is a range of fixed-displacement external gear pumps, featuring axial hydraulic balance and a modular design. They are available in multiple size series with a wide displacement range, various shaft and flange configurations, and can be combined with POX series pumps to form modular units for complex hydraulic systems. Some models are optional with built-in filters for enhanced fluid cleanliness[4].
