Danfoss Series 45 Frame G Axial Piston Pump is an open-circuit high-performance pump made for a range of demanding hydraulic applications. These pumps comes with a dual servo piston design with a cradle-type swashplate, which ensures precise fluid flow control and working pressure. 45 Frame pumps are developed with polymer-coated journal bearings to support the swashplate. Furthermore, their sturdy design with bi-metal valve plates ensures low noise operation and high volumetric efficiency.

Danfoss Series 45 pumps has maximum displacements of 74 cm³/rev for the G74B type and 90 cm³/rev for the G90C variant. With a minimum pressure up-to 310 bar (4495 psi) and the maximum pressure up-to 400 bar (5800 psi), these pumps are suitable for heavy-duty tasks. These pumps feature with high-speed capabilities (speeds of up to 2800 rpm) to enable reliable operations even under the most demanding circumstances. Frame G Axial Piston Pump is a robust, proven designs, comes with a long service life.

These pump are versatile used in a variety of operational needs with a range of control options, such as load sensing (LS), remote pressure compensated (RP), and pressure compensated (PC). Additionally, the pump has optional adjustable displacement limiters that allows customers to fine-tune the performance as per their specific system requirements. Due to their compact size and proven durability, Danfoss Series 45 Frame G Axial Piston Pump is become a great option for any hydraulic system needing high efficiency and reliability.
