General Function:

Hydraulic pumps of type PGZ type are gerotor pumps with constant displacement. Via a driving disk, the shaft drives the inner rotor in the indicated direction of rotation. The inner rotor cogs with the gerotor to turn it. The tooth clearances opening in the suction range suck in the hydraulic fluid. The separation of suction and pressure range is implemented on the opposite side of the meshing area by means of a radial gap created by the tooth profile of the outer and the inner rotor sliding against each other. Within the pressure range, the hydraulic fluid is pumped into the pressure port by means of the chambers becoming smaller.
