4.9.1.1. Way Hydraulic Gear Pump
Use
A gear pump sends through the pressure
line the hydraulic oil from the suction line
after accelerating it with the rotating and
turning gears. Thus the mechanical en-
ergy from the motor is converted to hy-
drostatic energy.
Gear pumps work with suitab-
le hydraulic oils only.
