Series Variable Displacement Piston Pumps
These A3H Series variable displacement piston pump offer high pressure, high efficiency, high speed and low noise features. This pump series has been developed using Yuken's unique design concept and cumulative technologies.They are suitable for use with construction machinery and various industrial machinery ranging from presses to injection moulding machines.
The A7H series variable displacement piston pumps offer a displacement of 180,270 cm3/rev with a rated pressure of 35 MPa and a maximum pressure of 40 MPa, supporting high pressure / high flow applications. The non-drive side of these pumps can be connected to an additional pump with SAE connection to provide a combined pump.

These AR series pumps have been developed on the basis of the same design concept as A series pumps which are renowned for high efficiency and low noise level.Using an alminum body, the size of the pump is more compact and the mass is considerably reduced. The noise level has also been reduced.
Series Variable Displacement Piston Pumps
The A series variable displacement piston pumps are high efficiency swash plate type piston pumps developed using Yuken's unique technology to meet customers' needs for energy efficient and low noise solutions. These pumps support a wide variety of displacement sizes and control types and are widely used in various hydraulic systems.
