Liebherr DMVA/DMVAG Hydraulic Axial Piston Motors are designed as swashplates for open and closed circuits, that is specially constructed for mobile machinery . It has a very high power density and the inverse drive with a swivel angle of 22° is very efficient, making it ideal for applications that require a variable displacement to hydraulic motor.

These are also called flanged variable displacement double motors, available in nominal sizes from 165–108 to 215–165. The nominal pressure of the units is 6,527 psi (450 bar) and the maximum pressure is 7,252 psi (500 bar) absolute.

Liebherr DMVA/DMVAG have adjustable individually or in parallel in the driving gears . A shared connecting plate simplifies hydraulic line installation. Liebherr DMVA series is available with the most common controls, features an impressive high performance and efficiency.
