PGH-type hydraulic pumps are gap-compensated internal gear pumps with fixed displacement. The hydrodynamically mounted pinion shaft drives the internal gear. The pinion shaft and internal gear tooth clearances opening in the suction range suck in the hydraulic fluid and transport it to the pressure range. The suction and pressure range are separated by the radial compensation elements and the tooth engagement between the internal gear and pinion shaft.
