Understanding Bosch Rexroth Axial Piston Pumps
What is an Axial Piston Pump?
Axial piston pumps work on the principle of positive displacement and are designed to transfer fluids at high pressure efficiently. The working principle involves the motion of several pistons parallel to the rotation axis of a cylinder block. The pistons’ linear motion is created by the angled swash plate or bent axis, thus generating suction and discharge.
Axial piston pumps may find their fair share of applications in engineering, as they can handle high-pressure systems efficiently while possessing the advantage of being compact and efficient. They are found in applications, including:
