PVQ40 PVQ45 PVQ50

Vickers PVQ40 PVQ45 PVQ50 — axial piston pump 41, 45 and 50 cm³

Vickers PVQ40, PVQ45 and PVQ50 are variable displacement axial piston hydraulic pumps of the Quiet Series, manufactured by Eaton. The largest frame sizes in the standard PVQ series, forming a common design group with the same housing and SAE B flange. PVQ40 is rated for full pressure up to 210 bar; PVQ45 with its larger displacement is limited to 190 bar. A through-drive configuration is available. Used in machine tool equipment, hydraulic presses, industrial power units and any systems where acoustic noise level is critical. Open circuit.
