Parker PV Series Pump | PV016, PV063, PV140, PV180, PV270 | 350 Bar Variable Piston Pump

Parker PV Series Heavy-Duty Axial Piston Variable Pump

Product Overview: The Parker PV series is a high-pressure swashplate-designed axial piston pump engineered specifically for industrial Open Circuit systems. This series covers a comprehensive displacement range from the compact 16cc (PV016) to the heavy-duty 270cc (PV270). With a rated operating pressure of 350 Bar and exceptional shock resistance, the PV series is the preferred power source for heavy industries. By integrating advanced compensators (such as NMRC/NMMC Pressure Compensation), PV pumps ensure maximum energy efficiency and smooth operation even under complex load conditions.

Key Technical Advantages:

• Heavy-Duty High-Pressure Reliability (350 Bar): Rated at 350 Bar (5000 PSI) with peak capabilities reaching 420 Bar, featuring reinforced high-capacity bearings to ensure an extended service life in extreme environments.

• Low Noise Engineering: Optimized valve plate and pre-compression chamber technology significantly suppress fluid pulsations, maintaining industry-leading quiet performance even at full pressure.

• Versatile Control Modulations (NMRC/NMFC):

  • Pressure Compensation: Models like PV016R1K1T1NMRC feature high-sensitivity compensators that automatically de-stroke the pump when target pressure is reached, optimizing energy consumption.

  • Load Sensing (LS): Ensures the pump flow output precisely matches actuator demand, slashing system heat generation.

• Rapid Dynamic Response: Features extremely short response times for displacement adjustment, handling high-frequency cycles and instantaneous load fluctuations for precision in molding and pressing.

• Modular Configuration: Offers various mounting and connection options (e.g., K1/L1 Thru-Drive), allowing for tandem mounting of secondary pumps to facilitate compact power distribution.
