German Rexroth High Pressure Gear Pump with 28 cc/rev Displacement and 22 mm Shaft Size for Mobile and Industrial Machinery

The PGH Series stands out for its high pressure stability (supporting working pressures up to 250 bar for most models), compact structural design (saving installation space in hydraulic systems), and low noise operation (noise levels as low as 65 dB under rated conditions), making it ideal for continuous-duty industrial scenarios.

• Ensure the pump's rotational direction matches the system's requirements (reverse rotation can cause internal component damage)
• Keep the suction line length within 1 meter and avoid sharp bends to prevent insufficient oil suction
• Tighten the flange bolts to the torque specified in the manual (typically 18-22 N*m for standard models) to avoid oil leakage or housing deformation

First, check if the hydraulic oil level is too low (topping up to the standard level if needed); second, inspect for air bubbles in the oil circuit (bleeding the system to remove air); finally, check if the bearing is worn (replacing the bearing if there is excessive radial play).
