SELF-REGULATING PUMP FOR OPEN CIRCUIT OPERATION

•    -  optimum interaction with LHY Powertrain 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

Controls

•    -  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
