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.

17.8 mm²/sec [88 SUS].

The chart on the right shows allowable inlet pressure and speed at various displacements. Greater speeds and lower inlet pressures are possible at reduced displacement. Operating outside of acceptable limits reduces pump life.
