It is recommended to use hydraulic oil that meets ISO VG 46 or ISO VG 68 specifications. The oil should have good anti-wear and anti-oxidation properties, and the oil temperature during operation should be controlled between -10°C and 80°C to avoid affecting pump performance.

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.

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.
