The PGH5-3X/063RE11VE4 pump is part of the PGH High Pressure Gear Pumps series from Bosch Rexroth and supplies fixed-displacement flow for hydraulic automation tasks. Each shaft rotation moves 64.7 cm³ of fluid, giving precise volumetric delivery. Continuous operating pressure is 315 bar for normal service, while intermittent peaks are accepted up to 350 bar during brief overloads. A maximum flow rating of 189 l/min supports high-demand circuits, and the unit must run at no less than 200 rpm to maintain lubrication and efficiency. Clockwise rotation sets the drive orientation, and the assembly weight of 41.668 kg affects mounting considerations in power units.
The pump works with HLP, HEES, and HFDU fluids so it can serve mineral-based or fire-resistant systems. An absolute inlet pressure of at least 0.8 bar prevents cavitation at startup and low suction conditions. Fluid enters through a 2 in suction port and exits through a 1 1/4 in pressure port, matching common hose sizes in industrial skids. FKM seals resist heat and aggressive additives to keep leakage low. Starting is permitted with oil viscosities up to 2000 mm²/s, allowing cold-temperature operation without damage. The housing mounts via a 160B4SW flange that conforms to ISO 3019-2, which simplifies replacement in standardized manifolds and reservoirs.
