XB01FO Series Fixed-Displacement Axial Piston Pumps with Swashplate Design, intended for hydrostatic transmissions in open circuits used in both mobile and stationary applications. Their flow rate is directly proportional to both rotational speed and displacement. Compared with the XB01VSO Series Variable-Displacement Axial Piston Pumps with Swashplate Design, the XB01FO Series offers distinct advantages in terms of flow pulsation, system pressure, service life, noise level, and cost. For a fixed-displacement pump, operating speed is directly proportional to output flow rate and remains unaffected by other factors—making it especially suitable for hydraulic systems requiring high output-flow stability. These pumps serve as direct replacements for imported Bosch Rexroth A4F Series axial piston pumps.
