D1 High Power Open Circuit Pumps
65/130/145/193/260 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), 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.
