PGF1-2X/5,0RL01VM Internal Gear Pump R900086170

The Bosch Rexroth PGF1-2X/5,0RL01VM internal gear pump, material number R900086170, is a fixed-displacement hydraulic pump for reliable hydraulic flow supply in industrial and mobile hydraulic systems. Bosch Rexroth official Store identifies this item as INTERNAL GEAR PUMP PGF1-2X/5,0RL01VM. For accurate purchasing and replacement, the complete model and material number should always be used together: PGF1-2X/5,0RL01VM / R900086170.

According to Bosch Rexroth RE 10213 technical data, PGF pumps are leak-gap-compensated internal gear pumps with fixed displacement. The PGF series is designed for low operating noise, low flow pulsation, high efficiency even at low viscosity and long service life through slide bearings and sealing gap compensation. For this specific PGF1-2X/5,0RL01VM internal gear pump, the model code indicates frame size 1, component series 2X and size 5.0. Bosch Rexroth data for size 5.0 lists a geometric displacement of 5.0 cm³/rev.

The complete model code PGF1-2X/5,0RL01VM contains important configuration details that must not be shortened during procurement. The PGF section identifies the Bosch Rexroth internal gear pump family. The 1 section indicates frame size 1. The 2X section indicates component series 20 to 29, with unchanged installation and port dimensions within the same component series range. The 5,0 section identifies the 5.0 displacement size. The R code indicates clockwise rotation when viewed on the drive shaft. The L code identifies the drive shaft version, the 01 code identifies line thread connection according to ISO 228-1, the V code indicates FKM seals, and the M code indicates the mounting flange version.

Bosch Rexroth technical data for size 5.0 lists an input speed range of 600 to 3600 rpm. The same table lists continuous outlet pressure of 180 bar, intermittent outlet pressure of 210 bar, and flow of 7.2 l/min at 1450 rpm, 10 bar and 30 mm²/s viscosity under the stated test conditions. These values should be reviewed together with the machine hydraulic schematic, actual operating speed, suction conditions, oil viscosity, filtration level and system pressure limitation before installation.

The operating principle of the Bosch Rexroth PGF1-2X/5,0RL01VM internal gear pump R900086170 supports quiet and stable hydraulic performance. The pinion shaft drives the internally toothed ring gear. During rotation, chamber volume increases on the suction side and hydraulic fluid flows into the pump. The segment assembly separates the suction chamber from the pressure chamber, and the fluid is displaced through the pressure channel as the teeth mesh again. This internal gear pump design helps reduce flow and pressure pulsation, supporting low-noise operation.

The PGF design uses axial and radial compensation to maintain efficient sealing between rotating and fixed pump parts. Bosch Rexroth technical data describes the pump construction as including the housing, bearing cover, end cover, ring gear, pinion shaft, slide bearings, axial discs, stop pin and segment assembly. These design features help the PGF series provide stable flow, good suction behavior and reliable service life in suitable hydraulic applications.

The PGF1-2X/5,0RL01VM internal gear pump is suitable for hydraulic power units, machine tools, production machinery, lifting equipment, mobile hydraulic systems, compact industrial equipment and other circuits requiring a fixed-displacement internal gear pump. Because Rexroth PGF pumps are available with different frame sizes, displacements, shaft designs, rotation directions, port connections, seal materials and mounting flanges, replacement should not be based only on appearance.

For procurement teams and maintenance engineers, the key purchasing reference is the complete Bosch Rexroth model PGF1-2X/5,0RL01VM together with material number R900086170. Short descriptions such as “PGF1 pump” or “Rexroth internal gear pump” are not enough for accurate replacement. Buyers should confirm the full model code, material number, displacement, rotation direction, shaft version, line connection, seal material and mounting flange before ordering.

Before installing or replacing this pump, hydraulic operating conditions should also be checked. Important points include inlet pressure, pressure line design, suction line design, hydraulic fluid type, viscosity range, cleanliness level, operating temperature, air bleeding and pressure relief protection. Bosch Rexroth notes that the system must provide pressure safeguarding so that the permissible pump operating pressure is not exceeded.
