FAQ:

What precautions should be taken during the installation of PGH Series Gear Pumps?

• 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.

3. How to resolve abnormal noise from a PGH Series Gear Pump during operation?

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).

4. How often should maintenance be performed on PGH Rexroth Gear Pumps?

For general industrial applications, 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.

5. Can PGH Rexroth Gear Pumps be used in high-temperature environments for a long time?

No. 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.
