Axial Piston Pump Design

What hydraulic piston pumps are used for

Axial piston pumps are widely used throughout the mobile and industrial sectors. They are generally the pump of choice for flows over 5L/min and up to 415 bar, if budgets allow.

In general, the swash plate design is used for pumps and the bent axis design for motors although there are applications where this is not the best solution.

The duty life can be as high as 10000 hrs, full load operation, which makes them ideal for continuous duty industrial power units and heavy-duty mobile applications. Manufacturers tend to have a range of different pumps available that are tailored to suit the cost and duty of different industrial sectors.

It's difficult to give exact pressure ranges etc as there are so many different versions available. Supplier experts will always advise on specific applications but this training is to make you aware of the important areas so that you better understand and can, therefore, diagnose issues with your equipment.

Essentially axial piston pumps are used on high-performance equipment, typically heavy duty industrial, continuous operation, high pressure 315 bar and above. Mobile excavators and wheel drive systems.

Lower cost versions have been produced in recent years and because of their high-performance, duty rating and clean operation, they have become more widely used.
