Design characteristics

  • Axial piston pump in swashplate design for high pressure open loop 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 rugged load sensing controls
  • SAE high pressure ports
  • SAE mounting flange with ANSI or SAE spline shaft
  • through shaft SAE A, B, B-B and C
  • optional tandem and multiple pumps

Regulator types

  • LP Load sensing with hydraulic pressure cut-off
  • E1L Load sensing with electrical override
  • TL Load sensing with mechanical power limiter
