Bosch Rexroth gear pump PGM5-3X/100RA11VU2
Note: The Bosch Rexroth PGM series is essentially internal gear pumps with constant displacement, which are often confused with external gear pumps. The following presents the models and key parameters of the PGM series in detail for reference.
The PGM series mainly includes the 4X and 3X sub-series, with frame sizes 4 and 5, and covers a displacement range of 25 cm³ to 160 cm³. It is optimized for variable-speed drives, featuring low noise, low pulsation and high efficiency thanks to gap compensation technology.
