The PGH5-3X/100RE11VU2 pump belongs to the PGH High Pressure Gear Pumps series from Bosch Rexroth and serves as a compact source of hydraulic power in automated machinery. It moves 5.24 cm³ of fluid each revolution, and at 1450 rpm with mineral oil at 10 bar and 46 mm²/s it provides 7.5 l/min to downstream actuators. Size code 5 governs its housing dimensions, while clockwise rotation aligns with common electric-motor drives. The pump starts at 600 rpm and can run up to 3000 rpm, covering most industrial speed ranges. An ISO 3019-1 two-hole flange (U2) seats the unit to standard mounting faces, and an FKM seal keeps high-temperature oil contained. Overall weight is 4.3 kg, which simplifies handling during assembly.
Continuous service pressure reaches 315 bar with mineral oils, and short-term peaks are limited to 350 bar to absorb load transients. Fluid cleanliness must meet ISO 4406 class 20/18/15 so that gear surfaces remain free of abrasive particles. Acceptable viscosity falls between 10 mm²/s and 300 mm²/s during normal running, while a starting limit of 2000 mm²/s prevents damage when cold oil is thicker. These viscosity windows maintain a stable lubricating film across seasonal temperature shifts. The pressure, cleanliness, and viscosity ratings combine with the previously stated speed range to deliver consistent flow for presses, machine tools, and similar hydraulic automation tasks.
