Abstract
This paper outlines the design philosophy and evaluation of the new “H” series variable displacement, medium pressure, open-circuit, axial piston hydraulic pumps. The “H” series is based on previously existing, technically successful, rotating group designs, but has significant design improvements affecting the areas of:
-
Unit Weight
-
Envelope Size
-
Ease of Assembly, Disassembly, Repairability and Modification
-
Alternate Fluid Capabilities
The “H” series is a family of naturally aspirated pumps nominally rated at 250 or 275 bar (3625 or 4000 psig), depending on system operating parameters. The geometric displacements of the four units in the series are as follows:
-
57cc (3.5 cu. in./rev.)
-
74cc (4.5 cu. in./rev.)
-
98cc (6.0 cu. in./rev.)
-
131cc (8.0 cu. in./rev.)
