PGH Series Hydraulic Internal Gear Oil Pump PGH2 PGH3 PGH4 PGH5 PGH5-21/160RE07VU2 fixed displacement pump
| PGH Series hydraulic internal gear oil pump PGH2 PGH3 PGH4 PGH5 PGH5-21/160RE07VU2 fixed displacement pump |
| Describe |
Frame size 4 and 5 Component series: 3X Maximum operating pressure 350 bar Maximum displacement volume 250 cm3 |
| Hydraulic pumps of type PGH.-3X are gap-compensated internal gear pumps with fixed displacement. |
| They mainly consist of: Mounting flange, housing, cover with through-drive, pinion shaft, internal gear, sliding bearings, axial washers and stop pin as well as the radial compensation consisting of segment, segment support and the seal rolls. |
| The hydro-dynamically mounted pinion shaft drives the toothed internal gear in the direction of rotation shown. The tooth clearances opening in the suction area prime the fluid. The fluid is transported into the tooth clearances of pinion and internal gear, from the suction area into the pressure area. |
| The radial compensation elements consist of segment, segment support and seal rolls. |
