• 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.

• Check if the hydraulic oil level is too low (topping up to the standard level if needed)
• Inspect for air bubbles in the oil circuit (bleeding the system to remove air)
• Check if the bearing is worn (replacing the bearing if there is excessive radial play)

• Routine inspection (checking oil level, temperature, and leakage) should be conducted monthly
• Oil change and filter replacement are recommended every 6 months or after 2000 hours of operation
• A comprehensive disassembly and inspection of the pump should be carried out every 2-3 years

The maximum allowable long-term operating temperature of PGH Rexroth Gear Pumps is 80°C. Prolonged use in environments exceeding this temperature will accelerate the aging of internal seals and bearings, significantly reducing the pump's service life and even causing sudden failures.
