Data Sheet D1 High Power Open Circuit Pumps 065/130/145/160/193/260/290 cm³ The new D1 pump is a high-pressure, highperformance variable axial piston pump, developed specifically for open-circuit systems in the most extreme application environments. Its robust design makes it an ideal solution for concrete machinery, mining machinery, cranes, drilling machinery, offshore, marine, and oil and gas equipment. The D1 expands the Danfoss open circuit pump portfolio to include higher hydraulic power product options for customers. It’s designed to work seamlessly with the new PVG 128/256 high flow valves, providing OEMs a full hydraulic system portfolio. The D1 pump is offered with five displacement options (65cc-260cc)four displacement options (130cc-260cc), a wide range of control options (pressure, load sense, power limiting and displacement controls), output pressure up to 350bar [5000psi] continuously, 400bar [5802psi] intermittently, and an integral charge pump allows the D1 pump to run at speeds up to 2500rpm. The D1 pump was developed and designed with global expertise, and customers will benefit from the strong local service provided by Danfoss. Danfoss offers technical support through its wide network of local distributors in more than 100 countries.
