Product Overview
The Parker Denison PAVC33R4226 is a variable displacement axial piston pump engineered for open-circuit industrial hydraulic systems requiring precise flow control and high operating efficiency. Manufactured by Parker Hannifin under the Denison brand, this pump utilizes a proven swashplate design in which multiple pistons reciprocate within a rotating cylinder barrel, with displacement varied by adjusting the swashplate angle through an integrated compensator control. The PAVC33 series is recognized for its robust construction, low noise signature, and fast response to system pressure changes, making it a preferred choice for demanding applications where accurate flow and pressure regulation are essential. With a nominal displacement of 33 cm³/rev, the PAVC33R4226 delivers reliable performance across a wide range of industrial duty cycles.

Engineering Features & Advantages
- Precision Performance: Swashplate axial piston design with tight-tolerance cylinder barrel and valve plate delivers high volumetric efficiency and consistent flow across the full pressure range.
- Variable Displacement Control: Integrated compensator adjusts swashplate angle to match system demand, reducing heat generation and energy consumption compared to fixed-displacement alternatives.
- Low Noise Operation: Optimized piston kinematics and rigid housing construction minimize vibration and airborne noise, suitable for noise-sensitive industrial environments.
- Industrial Reliability: Heavy-duty bearings and hardened internal components are built for continuous operation under severe industrial conditions.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Parker Denison PAVC33 series mounting and porting standards.
Typical Industrial Applications
The PAVC33R4226 is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, and construction or marine hydraulic systems where variable flow and high-pressure capability are required. Its responsive compensator control makes it particularly well-suited for applications involving frequent load changes, holding circuits, and multi-actuator systems demanding stable pressure and flow characteristics.
