Hydraulic Pump A4FO28/32L

The A4FO28/32L is a heavy-duty fixed-displacement axial piston pump built for open-circuit hydraulic systems, trusted in concrete pumps and construction machinery. Its swashplate design ensures stable, consistent performance under high-pressure working conditions.

This pump delivers reliable power with a nominal pressure of 400 bar and a peak pressure of 450 bar, matching the demands of heavy-duty applications. The output flow stays proportional to drive speed and displacement, ensuring precise hydraulic power delivery for your equipment.

Built for durability, the A4FO28/32L features excellent suction capabilities and low-noise operation, even during extended runs. High-quality materials and precision machining minimize wear, extending service life and reducing maintenance needs on job sites.

A key advantage is its through-drive shaft, enabling easy series connection with additional pumps for combined hydraulic power setups. The compact, optimized housing fits tight installation spaces without sacrificing power density, ideal for mobile and stationary equipment.

Compatible with standard HLP mineral oil per DIN 51524, this pump suits most common hydraulic fluids. It is a direct, reliable replacement for original A4FO28/32L units, ensuring seamless integration and consistent performance for your hydraulic systems.
