The PGH3-2X/011RE07VU2 gear pump is produced by Bosch Rexroth within the PGH High Pressure Gear Pumps series for hydraulic automation where compact fixed-displacement units supply actuators with consistent flow. Its displacement is 11.0 cm³ per revolution, so each shaft turn delivers a known volume to the circuit. At 1450 rpm with mineral oil at 10 bar and 46 mm²/s viscosity, the pump outputs 15.8 l/min, a figure used to size reservoirs and cooling devices. Continuous service is permitted up to 315 bar, giving machines a stable working pressure, while a peak limit of 350 bar handles short overload events without damage. The unit accepts starting viscosities as high as 2000 mm²/s, allowing cold-start operation with heavily viscous fluids. Rotation is clockwise, making it suitable for right-hand shaft drives commonly found on industrial motors.
Maximum shaft speed is 3000 rpm, which defines the upper limit for prime mover selection and cavitation avoidance. The housing mounts with a 2-hole ISO 3019-1 flange, and a pilot diameter of 101.6 mm h8 centers the pump precisely on the motor faceplate. Pressure and suction connections follow the ISO 6162-1 SAE flange pattern; the pressure port is DN13 (SAE ½″) to accommodate high-pressure hoses, while the suction port is DN25 (SAE 1″) to minimize inlet losses. FKM seals resist heat and mineral oil additives, extending service life in harsh duty cycles. Hydraulic cleanliness must not exceed ISO 4406 (c) 20/18/15, so filtration equipment has to keep particle contamination below this class. The pump weighs 4.8 kg, light enough for single-person installation yet robust for fixed mounting.
