Parker PAVC Series Pump | PAVC100, PAVC65, PAVC38 | 210 Bar Variable Piston Pump

Parker PAVC Series High-Performance Variable Axial Piston Pump

Product Overview: The Parker PAVC series is a range of high-pressure swashplate-designed axial piston pumps engineered for Open Circuit hydraulic systems. This series covers essential industrial displacements including 33cc, 38cc (PAVC38), 65cc (PAVC65), and 100cc (PAVC100). The standout feature of the PAVC series is its hydrostatic-bearing support structure, which delivers exceptional durability even when handling challenging media or operating under high-cycle conditions. With advanced control options like the Type R Pressure Compensator, PAVC pumps provide precise, energy-efficient, and rapid-response hydraulic power for machine tools, injection molding, and heavy industrial presses.

Key Technical Advantages:

• Hydrostatic Bearing Support: The unique hydrostatic design eliminates direct metal-to-metal contact, drastically reducing friction and wear. This allows the pump to maintain an extended service life under poor lubrication or harsh fluid conditions.

• High Responsiveness & Stability: Features ultra-short compensator response times, ensuring smooth and lag-free pressure transitions during complex machining cycles or high-frequency reversals.

• Superior Contamination Resistance: The rugged internal architecture offers better tolerance for fluid impurities than comparable piston pumps, effectively reducing downtime and maintenance in demanding industrial environments.

• Low-Noise Engineering: Specialized valve plate designs and pre-compression chambers effectively suppress flow pulsations, maintaining quiet and stable performance even at the rated 210 Bar pressure.

• Modular Controls (R42):

  • Type R Control (PAVC10038R4222): Features standard pressure compensation that automatically de-strokes the pump when target pressure is reached, optimizing energy consumption.
