The PGH5-2X/080RR11VU2 gear pump belongs to the PGH High Pressure Gear Pumps series and is built by Bosch Rexroth for hydraulic automation circuits. With a displacement of 81.4 cm³ per revolution, it moves a defined volume each shaft turn to support predictable actuator motion. At 1450 rpm and 10 bar with 46 mm²/s oil, the pump delivers 116.9 l/min, giving designers a reference flow rate for sizing valves and cylinders. A continuous operating pressure of 210 bar allows the unit to sustain heavy-duty loads, while an intermittent limit of 250 bar accommodates short pressure peaks without damage. The shaft is configured for clockwise rotation so drive motors must match this direction. These characteristics position the pump for constant-duty power units where stable flow and high working pressure are required.
The pump operates between 400 rpm and 2200 rpm; the lower limit maintains hydrodynamic lubrication, and the upper limit constrains mechanical stress and heat. An absolute inlet pressure of at least 0.8 bar is needed to prevent cavitation during high flow demand. A two-hole ISO 3019-1 U2 mounting flange secures the housing to standard motor adapters, while a 1-1/4 in SAE pressure flange (ISO 6162-2) and a 2 in SAE suction flange (ISO 6162-1) provide leak-free pipe connections. The fluid must meet ISO 4406 cleanliness class 20/18/15 so internal clearances remain wear-free. FKM seals withstand elevated temperature and common hydraulic oils, and a built-in through-drive lets an additional pump share the same prime mover. With a mass of 40.5 kg, the installation requires adequate support but remains manageable for conventional mounting brackets.
