Uchida-Rexroth PH100 & PH80 Pump | U-PH100-R-158C | PH80-R-229B | Variable Piston Pump

Uchida-Rexroth PH80 & PH100 Series High-Pressure Variable Piston Pumps

Product Overview: The Uchida PH series (including PH80 and PH100) is a range of variable axial piston pumps world-renowned for high stability and precise control in industrial and mobile hydraulic systems. This series is specifically engineered to meet the stringent demands of heavy-duty equipment for high-pressure responsiveness and long-cycle continuous operation. The range features core displacements of 80cc (PH80) and the high-power 100cc (PH100). Featured models such as the U-PH80-R-229B, PH100-MSZR-21-ESS1-100-10, and U-PH100-R-158C deliver unmatched performance. With superior volumetric efficiency and diverse control logic options, the PH series is the premier choice for large stamping presses, die-casting machines, steel mill hydraulic stations, and heavy machinery main drives.

Key Technical Advantages:

• Superior High-Pressure Performance: Equipped with reinforced rotating groups, ensuring extremely smooth flow output under rated high-pressure conditions while effectively minimizing pressure ripples.

• Intelligent Control Modalities: Offers various configurations including MSZR (Pressure Compensated Control) and ESS (Electronic Displacement Control), allowing precise matching with actuator loads for enhanced energy efficiency.

• Rugged Engineering: Built with high-capacity bearings and specially hardened piston groups, significantly extending the service life under harsh environments (e.g., high temperatures and vibrations).

• Quiet Operation Technology: Optimized valve plate geometry and pre-compression chambers significantly reduce hydraulic ripple and structural noise, enhancing the industrial workplace.

• High Interchangeability: Complies with SAE/ISO mounting standards, allowing for a seamless “drop-in” replacement of aging hydraulic pumps and simplifying maintenance or retrofit procedures.
