Nachi P & PH Series Pump | P16V, P70V, P130V, PH100, PH170 | Variable Piston Pump

Nachi P & PH Series High-Pressure Variable Piston Pump

Product Overview: The Nachi P and PH series axial piston pumps are the heavy-duty powerhouses of modern industrial hydraulic systems. The P series (covering P8, P16, P31, P70, P100, P130) is widely utilized in injection molding machines and machine tools, renowned for its ultra-quiet operation and extended service life. The PH series (covering PH80, PH100, PH130, PH170) is specifically engineered for heavy-duty applications, supporting rated pressures up to 31.5 MPa. Whether it is the precision of the P16VMR-10-CMC or the robust output of the PH series in forging equipment, Nachi delivers world-class hydraulic performance.

Key Technical Advantages:

• Ultra-Low Noise Performance: Utilizing Nachi’s patented noise-reduction technology, these pumps maintain quiet decibel levels even under full pressure, significantly improving the factory workspace.

• High-Efficiency Controls (CMC/EPC):

  • CMC Control: Models like the P16VMR-10-CMC feature high-sensitivity pressure compensation, de-stroking automatically during pressure-holding phases to slash energy consumption.

  • EPC Electro-Proportional Control: Supports integration with digital systems for real-time, stepless regulation of pressure and flow.

• PH Series Heavy-Duty Architecture: The PH series features reinforced rotating groups and swashplate supports, with rated pressures increased to 31.5 MPa to withstand grueling shock loads.

• Long-Term Operational Stability: Optimized valve plates and piston geometries ensure peak volumetric efficiency remains consistent during 24/7 continuous operation.
