The PGF1-21/3.2RE01VU2 internal gear pump belongs to the PGF Internal Gear Pumps series manufactured by Bosch Rexroth for hydraulic automation where compact flow generation is required. It displaces 3.2 cm³ of fluid per revolution and delivers 4.6 L/min at 1450 rpm and 10 bar. Clockwise rotation is mandatory, and a cylindrical output shaft simplifies direct coupling to electric motors. An aluminum housing holds overall mass to 1.0 kg, easing installation on small power packs. The unit runs from 600 rpm up to 3600 rpm, so variable-speed drives can regulate output across a broad range without cavitation or overheating.
System interfaces follow BSPP threads under ISO 228/1, with a G 3/8 suction port and a G 1/4 pressure port for standard pipe assemblies. An FKM seal retains hydraulic oil while resisting common additives. The pump can start with fluid viscosities as high as 2000 mm²/s and continue operating once viscosity falls to 10 mm²/s, permitting cold starts in unheated plants. Continuous pressure service is rated at 210 bar, and brief peaks up to 250 bar are accepted during load transients. These characteristics let the pump supply cylinders, servo valves, or pilot lines without exceeding design stress limits.
