The difference between Yuken A series and AR series piston pumps

A&AR series piston pump is a hydraulic piston pump with two series numbers, including A series and AR series. Apart from the different serial numbers, what are the differences between the two? Here are the differences between them:

1. Design structure: A series and AR series piston pumps are different in design structure. The A series piston pump adopts an axial piston arrangement, with the piston and the crankshaft arranged at an angle; while the AR series piston pump adopts a radial piston arrangement, with the piston and the crankshaft arranged at a right angle.

2. Working principle: The working principles of A series and AR series piston pumps are basically the same. They both generate pressure through the reciprocating movement of the piston in the piston hole. The difference lies in the arrangement and movement of the piston.

3. Pressure range: The pressure ranges of A series and AR series piston pumps are also different. Generally speaking, the AR series piston pump has a relatively high pressure range and is suitable for high-pressure hydraulic systems; while the A series piston pump has a relatively low pressure range and is suitable for medium and low-pressure hydraulic systems.

4. Purpose: Due to different design structures and pressure ranges, the applications of A series and AR series piston pumps are also different. A series piston pumps are usually used in medium and low pressure hydraulic systems such as engineering machinery, agricultural machinery and industrial equipment; while AR series piston pumps are often used in high pressure hydraulic systems such as metallurgical equipment, injection molding machinery and aerospace.

5. Dimensions and installation: A Series and AR Series piston pumps may also differ in size and installation. Specific dimensions and installation requirements can be selected based on actual application conditions and equipment requirements.

It should be noted that the above are general differences, and specific product specifications and performance parameters may be different. When selecting a suitable piston pump, it is recommended to refer to relevant product documentation and consult with the manufacturer or supplier to ensure that the selected piston pump meets actual needs.
