The PGP2-2X/008RE20VE4 pump belongs to the PGH High Pressure Gear Pumps series from Bosch Rexroth and is intended for hydraulic automation where compact, fixed-displacement sources are required. Its displacement of 8.2 cm³ per revolution permits a flow of 11.9 L/min at 1450 rpm, matching common electric motor speeds. A continuous outlet pressure of 250 bar supports stable circuit loading, while the 350 bar maximum operating pressure covers short peak demands. The pump is built for clockwise rotation so port orientation and drive coupling must follow that direction. Usable drive speed extends up to 1800 rpm to reach higher flow rates, and 600 rpm is the lowest speed that still ensures internal lubrication and volumetric efficiency.
To avoid cavitation the absolute inlet pressure must stay between 0.8 bar and 2 bar, establishing safe suction conditions. Hydraulic fluid temperatures are allowed from −10 °C to 80 °C so the unit can perform in moderate cold or warm environments. A minimum viscosity of 10 mm²/s secures a protective oil film, the normal running limit of 300 mm²/s prevents elevated drag, and start-up can proceed with oil as thick as 2000 mm²/s for cold starts. The assembly weighs 3.1 kg, a value that guides bracket selection and enables manual handling during installation.
