A word about the organization of this manual
General information covering all displacements of the H1 range is given in the beginning of this manual.
This includes definitions of operating parameters and system design considerations.
The next sections in the book detail the specific operating limitations for each frame and give a full
breakdown of available displacements, features and options.
General description of H1 family hydrostatic pumps
The H1 axial piston variable displacement pumps are of cradle swashplate design and are intended for
closed circuit applications. Flow direction is reversed by tilting the swashplate to the opposite side of the
neutral (zero displacement) position. The flow rate is proportional to the pump input speed and
displacement. The latter is infinitely adjustable between zero and maximum displacement.
The H1 family of closed circuit variable displacement axial piston pumps is designed for use with all
existing Danfoss hydraulic motors for the control and transfer of hydraulic power.
H1 pumps can be used together in combination with other Danfoss pumps and motors in the overall
hydraulic system.
