The PGH4-3X/020RE11VU2 pump is part of the PGH High Pressure Gear Pumps series from Bosch Rexroth, intended to move hydraulic oil in automated power units. It displaces 20.1 cm³ for every shaft revolution, giving a fixed flow rate proportional to speed. Clockwise rotation aligns with standard prime movers used in mobile and industrial equipment. A 25 mm shaft diameter accepts medium-torque couplings without special adapters, while the 2-hole ISO 3019-1 101-2 mounting flange permits direct installation on common pump brackets. The design allows operation from 200 rpm, supporting slow-speed circuits, and remains stable up to 3000 rpm when high flow is required. With a weight of 14 kg, the pump can be handled by a single technician during assembly.
The unit delivers 315 bar continuous pressure so actuators receive constant force, and it tolerates brief peaks to 350 bar for overload events. A fluid temperature range of –10 °C to 80 °C covers typical mineral oils, while an ambient window of –20 °C to 60 °C allows outdoor mounting in varied climates. The 3⁄4 in SAE high-pressure outlet port connects to reinforced discharge lines, and the 1 in SAE standard-pressure inlet minimizes suction losses. FKM seals withstand hot oil and additives for extended service life, and a built-in through-drive lets a second pump share the same prime mover when multiple circuits are needed.
