Bosch Rexroth AZPN Series External Gear Pump


The Bosch Rexroth AZPN pump is a fixed displacement external gear pump. It consists of a gear wheel pair and housing with a front and one rear cover. The drive shaft drives one of the two gear wheels which in turn drives the second gear wheel in the opposite direction.

On rotation, hydraulic fluid is entrapped in the gear chambers and delivered along the housing from the suction port to the pressure port. The flow per rotation roughly corresponds to the total of both gear chamber volumes.

The standard version 1X and 2X series pump sizes are: 20 | 22 | 25 | 28 | 32 | 36 cc/rev. Other features of the Bosch Rexroth AZPN gear pump include:
