The PGF2-22/006LN20VM-A313 internal gear pump is produced by Bosch Rexroth for the PGF Internal Gear Pumps series and supplies hydraulic circuits with steady flow for automation tasks where compact two-stage delivery is required. The larger stage has a displacement of 22.2 cm³ per revolution, delivering 31.9 L/min at 1450 rpm so actuators receive medium-volume flow without pulsation. Continuous pressure for this stage is limited to 180 bar, while intermittent duty can reach 210 bar to cover brief load peaks. A square flange conforming to DIN 3901/3902 provides the pressure port interface, and the housing mounts on a 2-hole centering Ø52 mm pattern to simplify alignment with standard motor adapters. The shaft carries two flats for a claw coupling, allowing direct connection to drive motors, the pump turns counter-clockwise, and operation is permitted up to 3000 rpm to give designers a broad speed window.
The second stage displaces 6.5 cm³ per revolution and provides 9.4 L/min at 1450 rpm, giving a dedicated low-flow source for pilot functions. Continuous operating pressure for this section is 210 bar, and intermittent peaks can reach 250 bar to accommodate short-term load spikes. HL or HLP fluids specified in DIN 51524 are required to ensure correct lubrication characteristics, and FKM sealing elements permit use at elevated oil temperatures. System filtration must achieve ISO 4406 class 20/18/15 so debris does not damage the internal gear profile. By combining two pressure ratings in a single housing, the pump reduces installation complexity and allows designers to assign distinct flow paths without adding extra drives.
