Description
First, it is necessary to correct a common misunderstanding: The PGM-4X series is an internal gear pump, not an external gear pump. Rexroth’s external gear pumps are mainly AZPG, AZPF, and other series.

  • Models with different mounting flanges and shaft extensions: e.g., PGM4-4X/032RT11VU2

IV. Supplementary Notes

  1. Difference from External Gear Pumps: Internal gear pumps have a more compact structure, lower noise, and smaller pulsation, making them suitable for noise-sensitive applications.
  2. Installation and Maintenance: Inlet and outlet ports are at right angles for easy configuration; the pump body can be rotated, and reverse fluid delivery can be achieved by changing the motor rotation direction.
  3. Operating Limits: Maximum operating pressure is 210 bar. It is recommended to use within the rated pressure range to ensure service life.
  4. Accessories: Compatible with gear pump repair kits, seal kits, installation kits, etc.
