Bosch Rexroth R918C01620 Hydraulic Gear Pump Assembly

The Bosch Rexroth R918C01620 is a triple-section external gear pump from the AZPFFF series designed for mobile hydraulic applications. It features three displacement stages rated at 12 cm³/rev, 14 cm³/rev, and 11 cm³/rev respectively. The pump configuration code LRR indicates counter-clockwise rotation for the first section and clockwise rotation for the second and third sections viewed from the drive shaft. Continuous operating pressure is rated at 200 bar (2900 PSI) per section with peak pressures up to 250 bar. The unit utilizes a standard SAE mounting flange and splined shaft configuration (KB/S0502). It is engineered for mineral-based hydraulic fluids operating within a temperature range of -20°C to +80°C. This assembly serves as a direct replacement for OEM part number R918C01620 and cross-references manufacturer codes AZPFFF-12-014-011-005-R and 0510565453. Typical applications include hydraulic systems on excavators and wheel loaders requiring multi-circuit flow delivery.
