Axial Piston Fixed Pumps – Power, Precision, and Reliability for Modern Hydraulics
Axial piston fixed pumps are a cornerstone of modern hydraulic systems, delivering consistent flow and pressure for a wide range of industrial and mobile applications. Known for their durability, high efficiency, and compact design, these pumps are essential for equipment that demands reliable power transmission under tough operating conditions.
What Are Axial Piston Fixed Pumps?
An axial piston fixed pump is a type of positive displacement pump where multiple pistons are arranged in parallel to the drive shaft. As the shaft rotates, the pistons move axially, drawing in hydraulic fluid and delivering it at a fixed displacement per revolution. Unlike variable pumps, the flow rate in a fixed pump is constant for a given speed, making them ideal for systems where demand remains steady.
Key Features and Benefits
Consistent Performance – Delivers a steady flow rate, ensuring predictable machine operation.
High Pressure Capability – Many models operate at nominal pressures of 350–400 bar, with peaks up to 450 bar.
Compact and Robust Design – Optimized for tight installation spaces without compromising power.
High Efficiency – Minimal energy loss during operation, reducing fuel or electricity consumption.
Long Service Life – Precision-engineered components resist wear, even under heavy-duty cycles.
Low Noise Operation – Advanced design reduces vibration and sound levels for operator comfort.
Applications of Axial Piston Fixed Pumps
These pumps are widely used in both mobile hydraulics (construction machinery, agricultural equipment, commercial vehicles) and industrial hydraulics (press machines, plastic molding, marine systems). Their high-pressure capability and reliable output make them suitable for tasks such as lifting, pressing, steering, and powering auxiliary systems.
Popular Series and Variants
Manufacturers like Bosch Rexroth, Parker, and Eaton offer various series such as the A2FO, A4FO, A17FO, and A17FNO. Each series is optimized for specific installation conditions, pressure ratings, and performance requirements.
Why Choose Axial Piston Fixed Pumps?
If your system requires a constant hydraulic flow with minimal maintenance and maximum efficiency, an axial piston fixed pump is a cost-effective and reliable choice. Whether in a crane, excavator, injection molding machine, or marine winch, these pumps deliver the performance needed to keep operations running smoothly.
