Danfoss 20-46-97901 K2R038 Series 45 axial piston pump in stock

Danfoss 20-46-97901 K2R038 Series 45 Frame K2 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.
