D1 High Power Open Circuit Pumps

D1P is a new generation of regulating axial piston hydrogenerators with an inclined plate into an open circuit. These hydrogenerators are designed to achieve high quality, reliability and efficiency in connection with simple installation into the hydraulic system.
D1P has been developed for the most demanding requirements for open-circuit hydrogenerators in mobile applications - it meets the highest qualification requirements of Danfoss. D1P Hydro Generators are ideal for applications such as concrete and mining, mining, crane and marine applications and others.
D1P are designed for trouble-free cooperation with PVG proportional distributors and PLUS + 1® controllers.

Designed for quality and reliability

• proven rotation group with 9 pistols
• drilling sandblasters at an angle improves suction power
• the ball sliding surface of the valve plate and the cylinder block ensures high speed while maintaining high efficiency

Advanced features

• the built-in filling pump enables the work of the hydrogenerator at higher revolutions
• ideal for working with the Danfoss proportional distributors of the PVG series
• control of the hydrogenerator in accordance with the standard Danfoss PLUS + 1®
• full torque transmission to auxiliary clamp flange for hydrogenerator - tandem
• electrical proportional control of geometric volume with the possibility of emergency manual control for diagnostics

Geometric volumes

• 130 cm³ without filling pump
