Danfoss Series 45 L and K frame open circuit piston pumps convert input torque into hydraulic power. The Series 45 L and K Frame hydraulic piston pump is available in a wide range of displacements and offers a full line of controls, pressures and configurations that have been engineered to fit your multiple application needs. Series 45 Frame L and K pumps have a single servo piston design with a cradle-type swashplate set in polymer-coated journal bearings.
Faster customized controls
Danfoss Series 45 offers a full line of displacements, controls, pressures and configurations that have been engineered to fit your multiple application needs. By utilizing proven, common components; the expertise of our system and applications engineers; and existing production sources for Series 45, Danfoss offers rapid prototyping and off -the-shelf solutions.
Series 45 Frame L and K pumps have a single servo piston design with a cradle-type swashplate set in polymer-coated journal bearings. A bias spring and internal forces increase swashplate angle. The servo piston decreases swashplate angle. 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 holds the piston slippers to the swashplate via the slipper retainer. The cylinder block rides on a bi-metal valve plate optimized for high volumetric efficiency and low noise. Tapered roller bearings support the input shaft and a viton lip-seal protects against shaft leaks.
An adjustable one spool (PC only, not shown) or two spool (LS and remote PC) control senses system pressure and load pressure (LS controls). The control ports system pressure to the servo piston, adjusting swashplate angle to control pump output flow.
