The PGF3-3X/020RE07VE4 internal gear pump belongs to the PGF Internal Gear Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits that require steady, low-pulsation flow. It is configured for clockwise rotation, so matching the drive direction prevents cavitation at start-up. A displacement of 20.6 cm³ per revolution defines the pump’s volumetric output each shaft turn, while a flow of 29.9 L/min at 1450 rpm and 10 bar gives designers a reference point for motor sizing. The minimum speed of 500 rpm ensures adequate hydrodynamic lubrication during slow cycles. Continuous duty is permitted up to 210 bar; transient loads can reach a pressure peak of 250 bar without harming the gear set. FKM sealing material resists mineral oils and high temperatures, extending service life. Fluid ports follow the ISO 6162-1 type 07 pattern, making the unit compatible with standard SAE flange blocks in compact manifolds.
The pump handles fluid temperatures from −20 °C to +100 °C, enabling reliable cold starts and safe operation in hot industrial environments without viscosity loss. To avoid vapor formation, inlet pressure must stay above an absolute 0.6 bar, and it must not exceed 3 bar so that boosted suction lines do not overload the shaft seal. An SAE 1 1/4 suction port offers a generous cross-section that lowers intake velocity and noise. Discharge oil exits through an SAE 3/4 pressure port sized for compact hoses that still withstand high working pressure. These connection dimensions simplify the selection of standard fittings, reduce installation time, and maintain consistent flow characteristics throughout the hydraulic system.
