Axial-Piston Pump

Jan. 11, 2007
The PVWJ open-loop axial-piston pump is designed for use in low-to-medium horsepower, industrial and mobile hydraulic applications.

Three frame sizes and 10 displacements are available. Six different control types permit field interchangeability without disconnecting from the drive or system piping. For large-volume circuits, individual use, or to drive auxiliary devices, the pump can integrally couple with two or more axial-piston, variable-delivery pumps through a single drive-shaft. A pressure-lubricated swash-block design provides high performance for high-pressure, high-cyclical operation. Features of the pump include a hardened-cylinder surface running on a hardened valve plate for contamination resistance and increased life; a quiet valve-plate design minimizes noise; SAE-keyed or SAE-splined shaft; sealed front-shaft bearing for operation with special fluids and side loading; up to 3,000 rpm; 5,800-psi maximum pressure; and maximum displacement ranging from 0.66 to 7.94 in. 3 /rev.
