Product Overview
The ATOS PFG-218-D 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 utilizes a pair of precision-machined, intermeshing gears to draw hydraulic fluid from the reservoir and deliver a continuous, non-pulsating flow to the system. The PFG series is specifically designed for industrial applications requiring reliable flow delivery, high volumetric efficiency, and quiet operation. As a critical power source in hydraulic circuits, the PFG-218-D serves as the primary pressure-generating component, converting mechanical energy from an electric motor or combustion engine into hydraulic energy for downstream actuators, valves, and cylinders.

Engineering Features & Advantages
- Precision Gear Geometry: The PFG-218-D features specially profile-ground gear teeth that ensure minimal internal leakage and high volumetric efficiency, maintaining consistent flow rates even under varying pressure loads.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, the pump incorporates durable journal bearings and a robust casing design that withstands high radial and axial loads.
- Low Noise Operation: Advanced tooth profile design and precise manufacturing tolerances significantly reduce pressure pulsations and noise emissions, making it ideal for noise-sensitive environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards ensures drop-in replacement without modification to existing mounting flanges or drive shafts.
- Contamination Tolerance: The external gear design offers inherent resistance to minor fluid contamination, providing a longer service life in real-world industrial environments compared to more sensitive pump types.
Typical Industrial Applications
The ATOS PFG-218-D gear pump is widely deployed across heavy industrial sectors. It is commonly found in plastic injection molding machines where consistent flow is required for clamping and injection cycles. In metallurgical presses and forging equipment, it provides reliable power for high-force actuation. The pump is also a standard component in construction and marine hydraulics, including excavators, cranes, and winches, as well as in CNC machine tools for lubrication and coolant delivery systems. Its robust design makes it suitable for any application demanding a dependable, fixed-displacement hydraulic power source.
