H1P series

Sauer-Danfoss Series H1P — hydraulic pump

Sauer-Danfoss Series H1P is a line of variable-displacement axial piston hydraulic pumps with displacements from 45 to 250 cm³ for closed-circuit hydrostatic systems. The pumps use a cradle swashplate design that reverses flow direction by simply tilting the swashplate through its zero-displacement position. The series is rated for a maximum working delta pressure of 480 bar and features an integrated gerotor charge pump with pressure-balanced port plates to minimise volumetric losses. Hydraulic, proportional electrohydraulic, discrete, and mechanical controls are available.

Advantages Sauer-Danfoss Series H1P

• Maximum delta pressure of 480 bar enables operation in the most demanding hydraulic systems of heavy mobile equipment
• Cradle swashplate design without a T-bar reduces the total number of parts and simplifies maintenance
• Integrated gerotor charge pump with balanced port plates minimises volumetric losses and maintains stable charge pressure without external units
• Single true clean side design with no operating ports on one face of the housing provides flexible placement in tight machine spaces

Applications Series H1P

Sauer-Danfoss Series H1P pumps serve as the primary hydrostatic drive in bulldozers, crawler excavators, pipelayers, and drilling rigs. The series is also widely used in compact track loaders, industrial snowcats, and grain and forage harvesters from John Deere, Claas, and Case IH.
