HAWE R Series Radial Piston Pump | R2.5A, R5.6A, R8.3, R9.8 | 700 Bar High Pressure Pump

HAWE R Series Ultra-High Pressure Radial Piston Pump

Product Overview: The German HAWE R series radial piston pump is the globally recognized benchmark for ultra-high pressure hydraulic technology. Featuring a unique valve-controlled design, this series spans from single-flow models like R2.5A, R5.6A, and R8.3 to complex multi-outlet configurations such as R3.3-1.7-1.7-1.7-1.7A. Engineered specifically for extreme environments, R series pumps can handle operating pressures up to 700 Bar. Its modular architecture allows for the integration of multiple independent piston elements within a single pump head, delivering synchronized yet independent flows—ideal for high-pressure clamping, synchronized lifting, and press controls.

Key Technical Advantages:

• Extreme High-Pressure Reliability: Rated for pressures up to 700 Bar (70 MPa). All pressurized components are crafted from high-grade bearing steel with precision heat treatment, ensuring zero fatigue damage over millions of cycles.

• Unique Multi-Circuit Capability: By combining different piston sizes (e.g., R9.8-9.8-9.8-9.8A), the pump provides precise, interference-free flow to multiple circuits simultaneously, simplifying complex system architectures.

• Superior Volumetric Efficiency: The valve-controlled mechanism maintains high volumetric efficiency even at peak pressures and offers excellent adaptability to variations in oil viscosity.

• Oil-Immersed Longevity: Typically designed for tank-mounted (immersed) installation, providing superior heat dissipation and full lubrication of moving parts, which significantly extends maintenance intervals.

• Modular Coupling Solutions: The “A” suffix indicates specific flange connections for seamless coupling with standard electric motors or integration as the high-pressure stage in two-stage pump systems.
