Product details
PGF1-2X Internal Gear Pump (Rexroth)
1. Model Code Explanation (PGF1-2X)
- PGF: Internal gear pump
- 1: Frame Size 1
- 2X: Series code
2. Main Technical Parameters (PGF1-2X Series)
- Displacement: 1.7–6.3 cm³/rev (common sizes: 1.7, 2.8, 5.0, 6.3)
- Max Pressure: 210 bar (continuous); 250 bar (intermittent)
- Speed Range: 600–3600 rpm
- Inlet Pressure: 0.6–3 bar (absolute pressure)
- Material: Aluminum alloy pump housing; steel gears and shafts; steel-backed tin-bronze bearings
- Weight: Approx. 1.0–1.14 kg (5.0 cm³/rev model)
3. Structure & Working Principle
Adopts internal gear design with driving external gear and driven internal gear, separated by a crescent seal. No trapped oil phenomenon, featuring low flow pulsation and low noise.
Equipped with axial and radial clearance automatic compensation, which minimizes leakage and maintains high efficiency even under high pressure, especially for low-viscosity hydraulic oil.
The pinion shaft is supported by fluid-lubricated plain bearings, and the internal gear uses static bearing support for long service life.
4. Performance Features
- Low operation noise
- High volumetric efficiency thanks to clearance compensation
- Wide adaptability to various oil viscosities and rotational speeds, excellent suction performance
- Compact structure, light weight and high power density
- Available for tandem assembly; compatible with PGH and PV7 piston pumps
5. Model Example (PGF1-2X/5,0RA01VP1)
- /5,0: Displacement 5.0 cm³/rev
- RA: Flange and port configuration
- 01: Version code
- VP1: Seal and shaft extension type
6. Typical Applications
- Industrial fields: Machine tools, automated equipment, low-pressure servo systems
- Mobile machinery: Construction machinery, forklifts, compact hydraulic power units
