PGH2-2X/008RR07VU2

The PGH2-2X/008RR07VU2 pump belongs to the PGH High Pressure Gear Pumps series produced by Bosch Rexroth and supplies hydraulic automation circuits with consistent high-pressure flow. Its geometric displacement of 8.2 cm³ per revolution defines the volume delivered each shaft turn, enabling accurate sizing of actuators. A nominal flow of 11.8 l/min at 1450 rpm and 10 bar provides adequate oil supply for moderate machinery. The unit withstands continuous mineral-oil pressure of 315 bar, allowing sustained force in pressing or clamping operations. It tolerates intermittent peaks up to 350 bar to cover short load spikes during rapid cycles. Compatibility with HLP, HETG, HEES, and HFD fluids lets the same pump serve mineral, biodegradable, or fire-resistant systems. Clockwise rotation when viewed on the shaft dictates drive motor direction and prevents reverse flow in fixed-displacement circuits. A DN13 pressure port with an SAE 1/2-inch connection standardizes the selection of high-pressure hoses.

Line connections are provided as an SAE flange in accordance with ISO 6162-1, creating a rigid joint that resists leakage under high load. The two-hole mounting flange specified by ISO 3019-1 allows direct attachment to common motor bell housings without adapters. A DN13 suction port of the same SAE 1/2-inch size keeps inlet hardware uniform and limits pressure drop at the pump intake. The cleanliness requirement of ISO 4406 (c) 20/18/15 mandates filtration that shields the gear set from abrasive particles. A maximum starting viscosity of 2000 mm²/s lets the unit start reliably with cold or viscous media before the system reaches operating temperature. The FKM shaft seal ring resists mineral and synthetic oils as well as elevated temperatures, reducing maintenance caused by seal wear. With a weight of 4.6 kg, the pump can be positioned by one technician and minimizes load on mounting structures.
