Series 45 Axial Piston Open Circuit Pumps Technical Information ...

Series 45 Axial Piston Open Circuit PumpsTechnical InformationFrames L and KDesignSeries 45 Frame L and K pumps have a single servo piston design with a cradletypeswashplate set in polymer-coated journal bearings. A bias spring and internalforces increase swashplate angle. The servo piston decreases swashplate angle. Ninereciprocating pistons displace fluid from the pump inlet to the pump outlet as thecylinder block rotates on the pump input shaft. The block spring holds the pistonslippers to the swashplate via the slipper retainer. The cylinder block rides on a bimetalvalve plate optimized for high volumetric efficiency and low noise. Tapered rollerbearings 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) controlsenses system pressure and load pressure (LS controls). The control ports systempressure to the servo piston, adjusting swashplate angle to control pump output flow.Frame K/L cross sectionLS adjustment screwLS control(attached to endcap)LS spoolPC spoolPC adjustment screwEndcap(axial ported)SwashplateBias springServo pistonTapered rollerbearingValve plateBlock springTapered roller bearingCylinder blockInput shaftShaft sealPistonSlipper retainerSlipperP101 659E22 520L0519 • Rev GK • March 2012
