PGH gear hydraulic pump

Hydraulic pumps of type PGH are gap-compensated internal gear pumps with constant displacement.
They basically comprise of housing , bearing cover , internal gear , pinion shaft , plain bearings , axial washers , end cover , mounting flange and stop pin , as well as the segment filler element consisting of segment , segment support and the seal rolls .
Suction and displacement procedure
The hydrodynamically supported pinion shaft drives the internally geared internal gear n the displayed direction of rotation.
During the rotation, there is a volume increase over an angle of approx. 90° in the suction range. An underpressure results and fluid flows into the chambers.
The sickle-shaped segment filler element separates suction and pressure chamber. In the pressure chamber, the teeth of the pinion shaft engage in the space between the teeth of the internal gear again. The liquid is displaced via the pressure channel .

We have the following pumps:

1.Axial Piston Pumps
2.External gearl pumps
3.Internal gear pumps
4.Gerotor pumps
5.Vane pumps
6.Radial piston pumps
7.Electrohydraulic pumps
If you have any inquiry please feel free to let me know .
