Pumps • Hydraulic Pumps • Hydraulic Piston Pumps

A hydraulic piston pump features an odd number of pistons arranged in a circular array within a housing, known as a cylinder block, rotor, or barrel. This housing rotates around an integral shaft that is aligned with the pumping pistons. Each time it does that, an equal amount of liquid is emitted. Hydraulic piston pumps come in two main designs: compact, economical axial piston pumps, and radial piston pumps for high pressure and small flows applications. They are used to power many machines (e.g., skid steer loaders) and to drive the screws of torpedoes. Leading manufacturers: Denison, Caterpillar, Komatsu, Bosch Rexroth, Vickers, Linde, Kawasaki, Dynex Hydraulics
