YUKEN “A3H” Series High pressure variable piston pump

YUKEN A3H series high-pressure variable piston pump is a swash plate piston pump developed by Youyan Company. It has the characteristics of high pressure, high efficiency, stability and reliability. The following are introduced in detail from four aspects: basic parameters, performance characteristics, model specifications, and application areas.：
1. Basic parameters
Maximum working pressure: 35MPa (some models may vary slightly, such as the rated pressure may be 100bar or 100kgf/cm2, and the maximum working pressure can reach a higher value).
Displacement range: 16.3 to 180.7cm3/rev (the specific displacement varies according to the model, such as A3H16, A3H37, A3H56, A3H71, A3H100, A3H145, A3H180, etc.).
Speed range: Adapt to the needs of different speeds, the specific speed needs to be determined according to the actual application, and the speed range of some models can reach 500rpm to 2300rpm.
Drive method: Usually driven by an electric motor or a diesel engine, some models support servo motor drive.
Medium: Hydraulic oil is usually used as the working medium, and some models are suitable for liquid media such as lubricating oil.

2. Performance characteristics
High-pressure and high-performance: it can provide stable high-pressure hydraulic power to meet the needs of various high-pressure hydraulic systems.
Load induction compensator: Equipped with a load induction compensator, it can automatically adjust the displacement according to changes in the system load to achieve energy-saving and efficient operation.
High volumetric efficiency: Even in a high-pressure environment, it can maintain a high volumetric efficiency and reduce energy loss.
Flexible adjustment: By adjusting the inclination of the swash plate, the displacement of the pump can be flexibly changed to meet different flow requirements.
Compact design: the output power/quality ratio is large, the design is compact, space-saving, and easy to install and maintain.
High protection level: Some models have a protection level of IP65 or higher, which can adapt to harsh working environments.

3. Model specifications
YUKEN A3H series high-pressure variable piston pumps contain multiple models. The following are some examples of common models and their suffix combinations.：
Basic model: A3H(16, 37, 56, 71, 100, 145, 180)
Examples of suffix combinations: LR01KK-10, FR01KK-10, FR09KK-10, etc.
Suffixes for specific functions or characteristics: such as 110A4K (indicating a displacement of 110A and equipped with a 4K drive shaft), etc.
