Technical Information	Series 45 H Frame Pumps

Frame H
Design	Series 45 Frame H 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.
	An integral, adjustable, two-stage control senses system pressure (PC and LS controls) and load
	pressure (LS only). The pump control ports system pressure to the displacement piston to control
	pump output flow.
