The Denison P8 series is a high-performance axial piston variable displacement hydraulic pump, designed for demanding open&close-circuit mobile and industrial applications. It utilizes a swashplate design to enable smooth, precise control of flow and pressure.
Key features include:
- Variable Displacement: Allows output flow to be adjusted from zero to maximum, matching system demand for improved efficiency and reduced heat generation.
- Pressure Compensation: A standard pressure compensator automatically adjusts displacement to maintain a preset system pressure, optimizing power usage.
- Robust Construction: Built with heavy-duty bearings and a hardened cylinder barrel for reliable operation under high continuous pressures (up to 420 bar).
- Control Versatility: Offers multiple control options like pressure compensator, load sensing, and horsepower limiting for sophisticated system integration.
- High Efficiency: Its axial piston design minimizes internal leakage, ensuring high volumetric and overall efficiency across a wide operating range.
Renowned for durability and performance, the P8 is commonly used in construction equipment, material handling, and industrial machinery where responsive, efficient hydraulic power is critical.
