Technical Information Series 45 H Frame Pumps
T
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.
