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.
