Original Rexroth A4FO Series Hydraulic Piston Pump A4FO22 A4FO28 A4FO40 A4FO71 A4FO125 A4FO250 A4FO500 Fixed Displacement Pump

A4FO22 / A4FO28 (Small Displacement): Ideal for light-duty hydraulic systems, including small automated equipment, precision machine tools, small lifting platforms and auxiliary hydraulic units. Features ultra-low noise and high precision for stable operation of small mechanical equipment.
A4FO71 (Medium Displacement): Suitable for standard engineering machinery, agricultural equipment, general industrial hydraulic stations and logistics handling machinery. Balances high efficiency and power output, meeting most conventional industrial hydraulic driving demands.
A4FO125 / A4FO180 (Medium-Large Displacement): Designed for medium and heavy-load scenarios such as concrete mixers, mining auxiliary equipment, large hydraulic lifting systems and industrial production lines with high power requirements.
A4FO250 (Large Displacement): Applied to heavy-duty mobile machinery, large-scale mining equipment, heavy industrial hydraulic systems and high-flow open-circuit drive equipment, providing strong and continuous high-flow high-pressure power support.
