REXROTH PGF Series 2X and 3X Internal‑Gear Fixed Pumps
Product Overview
The PGF‑2X and PGF‑3X are Bosch‑Rexroth fixed‑displacement internal‑gear pumps.
Designed with clearance‑compensation structure, they feature low‑flow pulsation and low noise, mainly used for open‑loop hydraulic circuits in industrial and mobile‑hydraulic applications.

Difference between 2X and 3X
2X = Previous generation: Mature standard version
3X = New upgraded generation: Optimized bearings, improved pressure‑fatigue life and upgraded seals. 3X is preferred for heavy‑duty conditions. Most mounting dimensions are interchangeable between 2X and 3X.
Key Advantages
Automatic clearance compensation, maintaining high volumetric efficiency under high‑pressure, low‑speed and low‑viscosity‑oil conditions.
Low flow pulsation and low noise, ideal for machine‑tools and noise‑sensitive equipment.
Plain‑bearing construction for long service life, capable of withstanding up to 2 million high‑pressure cycles.
Supports tandem drive for double‑pump / triple‑pump combinations to supply multiple hydraulic circuits.
Compatible media: Mineral oil HL/HLP, environmentally‑friendly synthetic hydraulic oil HEES/HEPR, etc.
Typical Applications
‑ CNC machine tools & automated production‑line hydraulic stations
‑ Forklifts, scissor lifts and light‑duty construction machinery
‑ Packaging machinery, rubber‑plastic equipment, conveyor systems
‑ Medium‑pressure, medium‑flow hydraulic power‑units
