SINGLE AND DOUBLE INTERNAL GEAR PUMPS, HG SERIES

HG Hydraulic pumps are gap-compensated internal gear pumps with fixed displacement.
The HG series has been developed particularly for the high requirements machine in industrial hydraulics fields.

FEATURES

  • circuit-board-1 Available single and double pumps (HG0, HG1 and HG2 series)
  • piston-2 Speed range up to 3000 rpm
  • prototype Nominal max pressure: 315 bar
  • piston-2 Nominal displacement: 4:160 cc/rev
  • gauge-1 Hydraulic fluid used: HLP, HFC, HEES, HFD-U
