Piston pumps are the "aristocrats" of excavator hydraulic systems and the most common choice for medium and large excavators. They use multiple pistons moving reciprocally within cylinders to alter working volume, achieving oil intake and discharge. Based on piston arrangement, they're mainly categorized as axial or radial piston pumps.

Axial piston pumps dominate modern excavators, with pistons arranged parallel to the drive shaft. When the swashplate (or tilt plate) angles relative to the drive shaft, the pistons reciprocate during rotation. Greater angles create longer piston strokes and larger pump displacement. Modern variable displacement piston pumps can adjust the swashplate angle in real time to modify output flow for different working conditions.

In excavators, hydraulic pumps play a vital role. Without them, even the most powerful engine couldn't transfer energy to working components like the bucket or boom. The performance of a hydraulic pump directly determines an excavator's efficiency, operational smoothness, and fuel economy. A high-quality hydraulic pump enables an excavator to be both "powerful" and "energy-efficient," which is why modern excavator manufacturers place such emphasis on hydraulic pump technology.
