Product Description
Nachi PVS Series High-Efficiency Variable Axial Piston Pump
Product Overview: The Nachi PVS series piston pump is synonymous with high efficiency and energy savings in modern industrial hydraulic systems. Featuring a unique “semi-cylindrical swashplate” design, this series covers a complete range of displacements from the compact 8cc (PVS08) and 16cc (PVS16) to the robust 70cc (PVS70). The PVS range achieves exceptional energy efficiency by drastically minimizing internal friction and leakage. With versatile control logics such as A1/A2/A3 Pressure Compensation or C1/C2/C3 Combination Control, it is perfectly suited for the dynamic power requirements of injection molding machines, CNC machine tools, and automated production lines.
Key Technical Advantages:
Superior Energy Savings: The semi-cylindrical swashplate reduces oscillation resistance. Combined with pressure compensation, it automatically de-strokes the pump during pressure-holding phases, cutting energy waste and heat generation.
High-Sensitivity Control Modes (A3/C1):
A1/A2/A3: Standard Pressure Compensator control, supporting precise settings for different pressure classes (e.g., A3 for higher pressure ranges).
C1/C2/C3: Combined Regulation, allowing for multi-stage pressure and flow switching to optimize complex machining cycles.
Rapid Dynamic Response: Features rapid displacement adjustment with ultra-short response times, ensuring precision and coherence for high-speed hydraulic actuators.
Low Noise & Extended Life: The patented valve plate design effectively suppresses fluid pulsations, maintaining quiet operation even at the rated 21 MPa pressure. High-strength internal components ensure stability under 24/7 continuous industrial duty cycles.
