Nachi VPPL Series Hydraulic Pump | VPPL-022, VPPL-016, VPPL-008 | Pressure Compensator

Nachi VPPL Series High-Pressure Axial Piston Variable Pump

Product Overview: The Nachi VPPL series is a high-pressure axial piston variable pump specifically engineered for compact and lightweight open-circuit systems. This series is a standard choice for metalworking centers, special-purpose machine tools, and small-scale injection molding machines. Known for its precision swashplate design and exceptional mechanical efficiency, the VPPL range delivers pressures up to 25 MPa with unmatched operational smoothness. Core models such as the VPPL-022PC5-R00S/20N feature an integrated pressure compensator that modulates flow based on load, achieving significant energy savings.

Key Technical Advantages:

• Superior Pressure Compensator Control (PC5): Equipped with high-sensitivity compensators. Models like the VPPL-016PC5-R00S/20N automatically reduce displacement to the minimum once the preset pressure is reached, preventing oil overheating and drastically cutting power consumption during pressure-holding phases.

• Rapid Response & Extended Service Life: Featuring specially treated piston groups and spherical port plates. Even in the high-frequency reversal cycles of the Series 20N, the pump maintains peak volumetric efficiency and offers high resistance to premature wear caused by hydraulic contamination.

• Ultra-Quiet & Low Vibration: Utilizing Nachi’s patented acoustic damping technology, the VPPL series maintains exceptionally low decibel levels even at maximum RPM and pressure, making it ideal for laboratories or precision machining workshops.

• Compact Series 20N Design: Adhering to Nachi’s latest design specifications. Whether it is the VPPL-008 or the VPPL-022, the mounting flanges, shaft splines, and R00S standard interfaces offer 100% physical compatibility for seamless maintenance and replacement.
