DDC Axial Piston Pumps
with Implement Pump, 20/24 cm³
For more than 40 years, Danfoss has been developing state-of-the-art components and systems for mobile machinery used in off-highway operations around the world. We have become a preferred supplier by offering the best of what really matters: The hardware inside your vehicle application.
Implement pump is an integrated charge pump that can be used for the lightly-loaded external work function.
Since implement pump has both external gear pump and charge pump functions, it allows customers to apply more compact sizing than existing system using external gear pump.
The DDC pump with implement pump is a high quality light duty pump which offers expanded functionality, great total efficiency, low noise, and easy installation.
The DDC pump is well suited for turf care applications, compact utility tractors, harvesters, small rollers, and agricultural vehicles.
