DDC Axial Piston Pump

The DDC20 is a compact and lightweight variable displacement axial piston pump intended for use in closed circuit low to medium power applications. DDC20 is a direct displacement control pump utilizing an advanced slipper piston design. The flow rate is infinitely variable between zero and maximum. The direction of flow is commanded by tilting the swashplate in one direction or the other from the neutral (zero flow) position. Reversing the direction of flow reverses the direction of motor rotation.
• Displacement 20 cm3/rev[1.22 in3/rev]
• Optional bypass valve and loop flushing valve
• Optional integral charge pump
• Compact design with best in class pressure ratings and durability
• Low noise
• Backed by a global network of Sauer-Danfoss service provider
