The Danfoss D1P series hydraulic pump is a high-performance solution designed to meet the demands of various mobile and industrial applications. It offers a range of displacement sizes from 65 cc to 290 cc, providing powerful hydraulic output for heavy-duty operations in construction, mining, forestry, and material handling.
Key Features:
1）High Power Density: The D1P pump delivers excellent power density, achieving maximum flow rates up to 667 liters per minute and operating at system pressures up to 350 bar continuously, with intermittent pressures reaching 400 bar. This makes it ideal for high-flow and high-pressure applications in demanding environments.
2）Efficiency and Durability: With a robust rotating group and low-friction roller-element cradle bearings, the D1P ensures long-lasting efficiency and reduced wear. This design minimizes the maintenance requirements compared to traditional pumps with sliding friction bearings.
3）Wide Range of Displacements: The D1P series is available in multiple displacement sizes, offering flexibility to meet various operational needs and enabling optimization for different machine types.
4）Flexible Control Options: This pump provides a range of control options, including pressure compensation and load sensing. Additionally, it offers electronic displacement control with manual override, giving users precise control over hydraulic functions.
5）Applications in Tough Environments: The D1P pump is ATEX-certified for mechanical control configurations, allowing it to be used in hazardous environments such as marine, oil, and gas, as well as in mining applications.
The Danfoss D1P hydraulic pump is an ideal choice for industries that require robust, high-performance, and flexible hydraulic solutions. With its high power density and versatility, it is capable of operating in some of the most challenging conditions.
