Sauer Danfoss ERR100B ERR130B ERR147C Hydraulic Piston Pump
Feature:
Series 45 Frame E 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 tothe swashplate via the slipper retainer. The cylinder block rides on a bi - metal valve plate optimized forhigh 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 PC) control senses system pressure and load pressure (LS controls). The control ports system pressure to the servo piston to control pump output flow.
