Product Overview
The BIERI AKP16 (Part No. 4054819) is a high-precision axial piston pump engineered by BIERI Hydraulik, a recognized specialist in compact hydraulic power units and high-pressure pump technology. Operating on the swashplate principle, this pump converts mechanical drive energy into hydraulic flow through a rotating cylinder barrel containing multiple axial pistons that reciprocate against an inclined swashplate surface. The AKP16 is designed for demanding industrial duty, delivering consistent volumetric displacement and stable pressure output in continuous-operation hydraulic circuits. Its compact axial piston architecture makes it particularly suited to space-constrained installations where high power density, precise flow control, and long service life are essential requirements.
