HPR-02 Self-regulating pump for open circuit operation high pressure

Displacement size from 55 to 165D

Product advantages

  • optimum interaction with Linde LSC control valves and LinTronic
  • energy saving operation by ‘flow on demand’-control
  • dynamic response
  • excellent suction up to rated speed
  • noise optimization over the whole range of operation
  • compact design
  • high power density
  • high reliability
  • long working life

Design characteristics

  • axial piston pump in swashplate design for high pressure open circuit systems
  • clockwise or counter clockwise rotation
  • self-priming at high nominal speed
  • tank pressurization or swash angle reduction for high speed applications
  • adaptive noise optimization SPU
  • decompression fluid is discharged via pump housing to keep suction side calm
  • exact and robust load sensing controllers with or without swash plate position feedback

Controller types

  • LP load sensing with pressure cut-off
  • H1L load sensing with hydraulic ΔpLS – override
  • E1L load sensing with electrical ΔpLS – override
  • LEP load sensing with electric stroke limiter and pressure cut-off
  • ETP electro-proportional with hyperbolic power-limiter and pressure cut-off
  • TL2 load sensing with hyperbolic power limiter
