Eaton Vickers 02-348676 Variable Displacement Piston Pump Assembly

The Eaton Vickers PVE21AR is an inline variable displacement axial piston pump designed for open-circuit hydraulic systems. It features a swashplate design that dynamically adjusts displacement to match system flow demand while maintaining constant pressure. The pump operates at a maximum continuous pressure of 210 bar (3045 psi) with a peak pressure capability of 250 bar (3625 psi). Full displacement is 45 cm3/r (2.75 in3/r) with a maximum rated speed of 2800 rpm at full flow conditions. The unit utilizes a lightweight aluminum housing with a SAE B 2-bolt mounting flange and a 1-inch keyed output shaft. Control options include pressure compensator and load sensing configurations for energy-efficient operation. The pump is engineered for horizontal mounting and requires mineral-based hydraulic fluid with filtration per ISO 4406 20/18/15. This replacement unit corresponds to Eaton Vickers part numbers 02-348676 and 02348676. It is interchangeable with Danfoss PowerSource code 411AK00101A and Vickers model codes such as PVE21R-9-30CC11. Typical applications include hydraulic systems in construction machinery such as excavators, wheel loaders, and agricultural tractors where reliable variable flow is required. The pump shares mounting flange and shaft dimensions with the PVE19 series, facilitating serviceability.
