German Original Rexroth Gear Pump with 315 bar Maximum Pressure and 28cc to 500cc Displacement

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.

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.
