The PGH5-2X/100RR11VU2 gear pump belongs to the PGH High Pressure Gear Pumps series manufactured by Bosch Rexroth. It supplies hydraulic automation systems with a fixed displacement of 100.2 cm³ per revolution, giving predictable volume per shaft turn. At 1450 rpm and 10 bar it delivers 143.8 L/min, so cylinders and motors receive steady flow during routine duty. The shaft is designed for clockwise rotation, matching common electric-motor drives. A permissible speed window from 400 rpm to 2200 rpm allows both slow jogging and high-output operation without cavitation. Startup suction can be maintained because the inlet may fall to 0.6 bar absolute, and the pump tolerates oil viscosities up to 2000 mm²/s during cold mornings. Use of HLP hydraulic oil conforming to DIN 51524-2 ensures seal compatibility and oxidation stability throughout the service life.
Continuous circuit pressure is supported at 160 bar, while short intermittent peaks up to 210 bar are accepted to handle brief load spikes in presses or machine tools. The housing carries an ISO 3019-1 two-hole mounting flange following SAE J744 so it bolts directly to standard motor adapters. Discharge plumbing connects to a 1 1/4 in SAE (H) port, simplifying hose selection in high-flow lines. Oil temperature may rise to +80 °C without degrading performance, and ambient air around the unit can reach +60 °C, letting the pump operate beside heat-generating machinery. A mass of 42.5 kg requires secure support brackets and assists in damping vibration during continuous duty. These characteristics qualify the pump for demanding high-pressure circuits where stable flow, standardized mounting, and elevated thermal limits are needed.
