The PGF1-21/1.7RA01VP1 pump belongs to the PGF Internal Gear Pumps series from Bosch Rexroth and supplies fixed-volume flow for hydraulic automation tasks. It displaces 1.7 cm³ of hydraulic fluid per revolution, producing a predictable output. A continuous pressure rating of 180 bar supports stable operation during normal duty. The unit can operate at speeds up to 4500 rpm and down to 600 rpm, giving a broad working range for different drive conditions. A centering diameter of 45.24 mm positions the body precisely on the mounting face. The two-hole flange defined by ISO 3019-2 provides straightforward installation, and the shaft rotates clockwise to match standard motor drives. Total weight is 0.8 kg, permitting easy handling during assembly.
At 1450 rpm the pump delivers 2.4 L/min, which suits low-flow control loops. It endures intermittent pressure surges up to 210 bar, allowing short-duration overloads. Permissible hydraulic fluid temperatures span from −20 °C to +100 °C so the pump can function in both cold starts and high heat situations. A pressure connection sized G 1/4 in accordance with ISO 228-1 links to downstream components, while the suction port uses the same G 1/4 thread for uniform piping. The shaft seal is manufactured from FKM to resist elevated temperatures and common oil additives, helping to maintain tightness over extended service. These interface and temperature limits define reliable performance in compact hydraulic manifolds.
