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.
The MP1 motor is designed for use primarily in mobile
equipment using existing and proven technology.
These motors have been optimized with regard to
options, life, package size and installed cost.
The MP1 motor is a fixed displacement axial piston
motor and is intended for closed and open circuit
medium power applications. These motors are
designed primarily to be combined with other
products in closed and open circuit systems to
transfer and control hydraulic power.
The MP1 motors consists of two displacements in one
package size. Three different configurations are
available, an SAE A, B and cartridge style two-bolt
configuration.
