Danfoss Frame H Open Circuit Axial Piston Pump - Series 45 is a variable displacement axial piston pump for open circuit applications. These pumps are designed to optimize performance, size, and cost, matching the work function requirements of the demanding mobile applications. Danfoss Frame H pumps are available with a dual-servo piston design combined with a cradle-type swashplate, which ensures precise control of fluid flow and high volumetric efficiency.

These pumps are available in two displacements, H57B and H75D, with a minimum pressure range of 210 bar and a maximum pressure range up to 410 bar. With a full line of displacements, controls, and mounting options, the Series 45 modular design approach reduces your time to market and provides a more competitive, reliable product to your customers. Furthermore, these pumps are available in various control options, such as optimized fan drive control (FDC), electronic displacement control (EDC), and electronic torque limiting (ETL).

Danfoss Frame H pumps are available with optimized valve plates for maximum efficiency and quiet operation, computer-moulded castings to optimize inlet conditions for maximum pump speed, and a compact package size, minimizing installation space requirements. Danfoss offers a wide range of product selections to meet the flow and pressure requirements of your individual application, including agriculture, construction, material handling, forestry, and mining.
