Design Features

  • High pressure axial piston pump in swash plate design for open loop systems
  • Clockwise or counter clockwise rotation
  • Self-priming at high nominal speed
  • Higher rotating speed by tank pressurization or swash angle reduction
  • Adaptive noise optimization SPU
  • Decompression fluid is drained via pump housing for suction side stability
  • Exact and rugged load sensing controls
 

Control Method

  • LS with hydraulic pressure cut-off
  • LS with hydraulic override
  • LS with electric override
  • LS with hyperbolic power limitation
  • LS with electro-proportional flow
  • Electro-proportional flow setting, hyperbolic power 
  • Limitation and pressure cut-off
 

Product Advantages

  • Optimal interaction with Linde LSC-directional control valves and LinTronic
  • Energy saving operation by "flow on demand" control
  • Dynamic response
  • Self-priming at high nominal speed
  • Adaptive noise optimization SPU
  • Compact structure
  • High power density
  • High reliability
  • Long life
