Danfoss E Frame Open Circuit Axial Piston Pump – Series 45

Danfoss E Frame Open Circuit Axial Piston Pump Series 45 is constructed in a single servo piston design with a cradle-type swashplate set in polymer-coated journal bearings. It is available with a bias spring and internal forces that increase swashplate angle. The servo piston decreases swashplate angle, which allows a smooth and controlled fluid transfer. It has nine reciprocating pistons displace fluid from the pump inlet to the pump outlet as the cylinder block rotates on the pump input shaft.

The block spring of the pump holds the piston slippers to the swashplate via the slipper retainer for a optimum operation. The cylinder block rides on a bi-metal valve plate that is optimized for high volumetric efficiency and low noise. Danfoss E Frame pumps comes with tapered roller bearings support the input shaft and a viton lip-seal protects against shaft leaks, which ensures a long-term use in most-demanding conditions.

Danfoss E Frame Open Circuit Axial Piston Pump Series 45 is designed with an adjustable spool design, with one spool (PC only) or two spools (LS and PC), which provides control as per the system requirement. The control mechanism senses both system and load pressures (LS controls) and then adjusts it accordingly. Additionally, Danfoss E Frame is constructed with the control ports system pressure to the servo piston to control pump output flow. This pump is specially designed for mobile and industrial applications.
