Sauer-Danfoss D1P Series — hydraulic pumps
Sauer-Danfoss D1P Series is a line of high-power variable-displacement axial piston hydraulic pumps for open-circuit hydraulic systems. The pumps are designed for heavy-duty mobile and industrial applications: continuous working pressure up to 350 bar, peak pressure up to 400 bar, and input speed up to 2,500 rpm. An angled piston bore cylinder block and spherical valve plate deliver stable rotation and high efficiency. An integrated charge pump enables full-speed operation without external charge pressure. The series is PLUS+1® compatible and designed for seamless integration with PVG 128 and PVG 256 high-flow valve sections.
D1P Series models
The series includes pumps:
All series are available in the Sauer-Danfoss hydraulics section.
Advantages of the D1P Series
- 145 cm³ displacement and peak pressure up to 400 bar deliver high power density in a compact housing
- Standard roller-element cradle bearings replace sliding friction bearings, reducing wear and extending service life under sustained cyclic loads
- A wide range of control options — pressure compensation, load sensing, electric proportional displacement, and mechanical power limiting — simplifies integration into virtually any circuit architecture
- ATEX certification on mechanical control configurations enables use in explosive atmospheres in oil and gas and mining environments
- Full-power through-drive capability allows additional pumps to be driven without power loss to the main circuit
Applications D1P Series
Sauer-Danfoss D1P Series hydraulic pumps are used in drill rigs, pipe handling equipment, hydraulic power units, artificial lift systems, and heavy-duty construction, mining, forestry, and material handling machinery. Compatibility with PVG 128 and PVG 256 valve banks makes the series an ideal system solution for high-flow applications requiring precise work function control.
