Variable Displacement Pump
H1 60/68 Tandem
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. H1 - our new
generation of servo-controlled hydrostatic pumps - is
no exception.
The H1 range is built around an advanced control and
available in a wide range of displacements. It is
designed for quality and reliability and offers
expanded functionality, greater total efficiency, and
easy installation.
All H1 control and sensor options are PLUS+1
Compliant. PLUS+1 allows you to rapidly develop and
customize electronic machine control. It opens up the
future by combining machine controls and
diagnostics in an integrated operating network.
