HA4VTG series

The HA4VTG series by Hytek is a range of variable displacement axial piston pumps with swashplate design, for closed-circuit hydrostatic transmissions. Featuring compact and lightweight construction to facilitate integration into complex hydraulic systems.

Details

  • Available displacements: from 71 cc to 100 cc, available in two series variants: Series 15 (nominal pressure 320 bar, maximum 400 bar) and Series 39 (nominal pressure 400 bar, maximum 450 bar)
  • Swashplate axial piston design
  • Closed circuit
  • Nominal pressure: 400 bar
  • Maximum pressure: 450 bar
  • Maximum speed: 3,050 rpm
  • Compatible fluid: mineral oil
  • Available controllers: mechanical lever control (HW), hydraulic pilot pressure control (HD), proportional electric control (EP, 12V/24V), on/off electric control (EZ, 12V/24V)
  • Through-drive available (with or without auxiliary pump)



 

 12-MONTH WARRANTY 

Benefits

  • Flow proportional to rotational speed and pump displacement, enabling multiple flow adjustment options
  • Integrated maximum pressure valves with overload protection on both A and B branches
  • Capable of operating under demanding conditions at high speeds, elevated pressures, dynamic loads and frequent flow reversals
  • Integrated charge pump

Application fields

  • Earthmoving machinery
  • Construction machinery
  • Forestry and agricultural machinery
  • Lifting (cranes) and material handling
  • Industrial and special-purpose vehicles
