VPA10V(S)O Series 52 & 53 Series Variable Piston Pumps: Compact Power and Efficiency

The Hydraport VPA10V(S)O Series 52 and 53 are high-performance, variable displacement axial piston pumps designed for open-loop hydrostatic drives in applications with medium pressure requirements. Used in both mobile and industrial settings, these pumps deliver output flow that is directly proportional to the drive speed and displacement, allowing them to provide power only when needed.

Performance Highlights

These pumps are engineered for optimal performance, especially under varying loads:

• Superior Efficiency: The built-in load-sensing circuit helps reduce fuel consumption and ensures excellent operating efficiency.
• Versatile Control: A wide range of controls with short response times is available, including DR, DRG, DFR, DFR1, DFLR, electro-hydraulic pressure control, electro-proportional swivel angle control, and power control.
• Robust and Compact: Features a favorable power-to-weight ratio and compact dimensions, along with stable bearing for a long service life and a low operating noise level.
• System Flexibility: Available in single and through-drive models to easily create multi-circuit systems. Multiple drive shaft options are also available.

Primary Applications

These pumps are particularly suited for applications requiring high power-to-weight and compactness:

• Mobile Machinery: Construction (excavators, loaders), agricultural (tractors, harvesters), and material handling (forklifts, cranes).
• Industrial Machinery: Hydraulic systems in machine tools, presses, and manufacturing facilities.
• Testing: Hydraulic test benches for component calibration.
