PGH4-3X/040RE11WU2

The PGH4-3X/040RE11WU2 gear pump belongs to the PGH High Pressure Gear Pumps series and is built by Bosch Rexroth for hydraulic automation where steady high-pressure flow is required. It turns clockwise, making alignment straightforward with right-hand electric motors used on common power units. A displacement of 40.10 cm³ per revolution fixes the volume transferred each shaft turn, giving predictable delivery across the speed range. The pump supports up to 120 L/min, so large cylinders or multiple valves can be fed without flow shortage at rated speed. Continuous circulation is possible from 200 rpm upward, which keeps oil moving during low-speed standby cycles. Its cast-iron housing resists internal stress and maintains dimensional stability, and the design accepts both HFC and HLP hydraulic fluids to suit fire-resistant or standard mineral-oil circuits.

Integration into existing equipment is aided by a 2-hole 101-2 mounting flange in accordance with ISO 3019-1, allowing direct attachment to standard motor faces. Pressure discharge is through a 1 in ISO 6162-2 flange port capable of handling the unit’s rated working pressures, while a 1 1/2 in ISO 6162-1 suction port minimizes inlet restriction during high flow demand. An NBR shaft seal ring combined with FKM static seals keeps leakage low over wide temperature and fluid ranges. A through-drive is available so an additional pump can be coupled in tandem when several hydraulic circuits must share one prime mover. The assembly weighs 16.52 kg, permitting single-person handling during installation or service.
