The PGF1-2X/2 8RA01VP1 internal gear pump belongs to the PGF Internal Gear Pumps series and is produced by Bosch Rexroth. It supplies hydraulic circuits with fixed displacement flow for industrial automation. The unit delivers 2.8 cm³ per revolution, allowing predictable volume output at rated speed. A continuous pressure rating of 210 bar supports steady actuator motion, while an intermittent limit of 250 bar provides short-term reserve for load peaks. Clockwise rotation when viewed from the shaft end defines motor coupling orientation. Operating speed ranges from 600 min⁻¹ to 4000 min⁻¹ so designers can match pump flow to variable drive speeds. A cylindrical shaft end with key according to ISO 3019-2 transfers torque without slip, and the 4 × 4 × 14 mm DIN 6885 key engages the driver hub securely. Mounting flange centering of 45.24 mm aligns the housing to standard motor adapters and minimizes radial misalignment during installation.
For fluid connections the suction port is threaded G 3/8 and the pressure port is G 1/4, enabling straightforward linkage to common BSPP pipework. Minimum operating viscosity is 10 mm²/s, and starting viscosity may reach 2000 mm²/s, which broadens the allowable temperature window during cold starts. The pump requires oil cleanliness class ISO 4406 20/18/15 to limit wear on the internal gears. An FKM shaft seal resists mineral oils and elevated temperatures, maintaining leakage control under full pressure. Overall weight is 1.0 kg so the unit adds little mass to compact power packs. These characteristics define the working envelope and ensure the pump supplies consistent flow across the specified pressure and speed range without compromising service life.
