Rexroth A4FO Series Fixed Displacement Axial Piston Pump

Product Overview: The Rexroth A4FO series is a high-performance, swashplate-design axial piston fixed displacement pump engineered specifically for open-circuit hydraulic systems. Renowned worldwide for its exceptional reliability, extended service life, and high power density, the A4FO series features key models like the A4FO22/32R-NSC12K01 and the massive A4FO500/30R-PPH25N00. It delivers extremely stable high-pressure power at a constant displacement output, making it the ideal choice for heavy-duty forging machinery, industrial power units (HPUs), and auxiliary systems in mobile equipment.

Key Technical Advantages:

• Extreme High-Pressure Durability: Rated for continuous operation at 350-400 Bar (5800 PSI) with peak capability up to 450 Bar, easily managing extreme load fluctuations and continuous high-intensity duty cycles.

• Superior Suction Characteristics: Optimized internal fluid passages ensure excellent self-priming capability even at high speeds, effectively preventing cavitation and ensuring smooth operation.

• Low Noise & Vibration: Utilizing precision swashplate geometry and a 9-piston rotating group, it significantly reduces hydraulic pulsation and mechanical noise for a better working environment.

• Robust & Compact Construction: Built with high-strength cast iron housings to withstand external impacts and thermal stresses in the harshest industrial environments.

• 100% OEM Standard Compatibility: Manufactured to strict Rexroth factory specifications (e.g., NSC12, PPH25 mounting codes), ensuring splined shafts and flanges align perfectly for a seamless “drop-in” replacement.
