Competitive Advantages

1. Gap compensation structure ensures high volumetric efficiency, less internal leakage and stable performance even under long-hour continuous high-pressure operation.

2. Low noise and low flow pulsation, much smoother output than external gear pumps, suitable for noise-sensitive hydraulic systems like CNC machine tools.

3. Compact cast iron housing and modular design, easy installation and maintenance, strong interchangeability within the Rexroth PGH3-2X series.

The Analysis for Rexroth PGH3-2X Gear Pump Commom Breakdown:

1. Insufficient output flow / pressure drop: Mostly caused by aging NBR seals, excessive internal wear of gear pairs or contaminated hydraulic oil.

2. Abnormal noise and vibration: Usually due to insufficient oil suction pressure, air entering the oil circuit, misalignment of coupling or bearing wear.

3. Oil leakage from shaft end or flange surface: Main reasons are seal damage, loose mounting bolts, excessive system backpressure or scratches on the mating surface.
