The PGF3-3X/040RE07VE4 pump is produced by Bosch Rexroth in the PGF Internal Gear Pumps series. It serves fixed-displacement supply duties in hydraulic automation circuits where predictable flow is needed. A displacement of 40.5 cm³ per revolution sets the volume transferred every shaft turn, and a rated flow of 58.7 L/min at 1450 rpm under 10 bar illustrates output at common motor speeds. The unit starts delivering at speeds down to 500 rpm, which helps machines that run slow cycles during setup. Rotation is clockwise to match right-hand drive arrangements in most power packs. The design accepts startup oil viscosities as high as 2000 mm²/s so cold-start damage is avoided. It fastens to motors through an ISO 3019-2 four-hole 100B4SW mounting flange, and pressure is discharged through a SAE 3/4 in port that simplifies connection to standard tube fittings.
The pump keeps systems pressurized continuously at 180 bar and permits brief rises to 210 bar for peak loads. Inlet oil arrives through a SAE 1 1/4 in suction port sized to limit velocity and avoid cavitation. Fluid cleanliness must meet ISO 4406 class 20/18/15 to preserve bearing and gear life. Power is transmitted by a 25 mm shaft, and an 8 × 7 × 30 mm key secures the coupling to the prime mover against torsional slip. The housing mass is 4.9 kg, allowing single-person handling during installation or service. Together these parameters establish a pump that delivers reliable pressure and flow for general hydraulic automation tasks.
