Parker PVP Series Piston Pump | PVP3336, PVP4136, PVP3320 | Variable Displacement Pump

Parker PVP33 & PVP41 Series Heavy-Duty Axial Piston Variable Pump

Product Overview: The Parker PVP series serves as the high-performance power core for industrial open-circuit hydraulic systems. Covering mainstream industrial displacements including PVP33 (33cc) and PVP41 (41cc), this range is custom-built for machine tools, injection molding, material handling equipment, and industrial power units (HPUs). Featuring an exceptionally rugged heavy-duty cast-iron housing, the PVP series delivers superior quiet-running excellence and fatigue resistance even at continuous pressures of 210 Bar. Core models like the PVP4136R2P11 and PVP33369R221 are renowned for their lightning-fast compensator response.

Key Technical Advantages:

• Rugged Heavy-Duty Construction: The reinforced cast-iron body is optimized for high-frequency load cycles. This construction not only extends mechanical service life but also significantly dampens hydraulic vibrations for maximum operating quietness.

• High-Precision Variable Control (A4/P11): Equipped with advanced control valve blocks. Models like the PVP33203R26A4M21 and PVP33303R6A421 support load sensing and pressure compensation, instantaneously modulating displacement based on demand for significant energy savings.

• Outstanding Power Density: Delivers high flow output within a compact installation footprint. The PVP33 and PVP41 series, through optimized swashplate mechanisms, ensure peak volumetric efficiency and stable torque output even at high speeds.

• Flexible Mounting Configuration: Strictly compliant with SAE porting standards. Offers various rotation options (e.g., R2 CW, R6 config) and shaft interfaces to ensure a seamless “drop-in” match for original OEM equipment, reducing maintenance costs.
