Series 45 Frame G pumps have a dual servo piston design with a cradle-type swashplate set in

polymer-coated journal bearings. The bias piston increases swashplate angle. The displacement

piston decreases swashplate angle. At equal pressure, the larger diameter displacement piston

overpowers the bias piston. 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.
