Parker Piston Pumps | P2/P3 Series

Parker P2/P3 Series Piston Pumps

The Parker P2/P3 Series hydraulic piston pumps are engineered to meet the demanding performance requirements of heavy-duty mobile applications. With continuous pressure ratings up to 350 bar (5,000 psi), these variable displacement piston pumps deliver exceptional power density, enabling equipment downsizing without compromising performance or reliability.

The P2/P3 Series piston pumps feature an optimized housing design and unique port layout for fast, cost-effective installation on mobile transmissions. A wide range of options allows customization to match specific application needs. The P2 serves as the standard configuration, while the P3 incorporates an internally boosted, supercharged inlet for high-flow performance under challenging inlet conditions.

Each model includes an integrated pre-compression volume, ensuring low-pressure ripple and reduced noise emissions, making the P2/P3 Series ideal for mobile machinery requiring efficient, quiet, and high-performance hydraulic power.
