Series advantages

  • Swashplate axial piston pump for closed hydraulic circuits

  • Smooth directional change of hydraulic fluid flow when swashplate passes neutral position 

  • Two pressure relief valves installed on high-pressure side to prevent overload

  • Built-in gear pump functions as both make-up oil pump and control pump

  • Maximum make-up pressure limited by integrated low-pressure relief valve

  • Newly designed rotating components and bearings enhance load capacity and rated speed

  • Optimized housing design reduces vibration and noise 

  • Multiple control options available to meet diverse industry application requirements

  • Various port connection configurations optimize piping connections
