High-Pressure Quantitative Hydraulic Gear Pump with Up to 500 l/min Flow Rate and 1000 cc/rev Displacement

Cavitation can cause pressure fluctuations and must be addressed by ensuring proper suction conditions.

• Overheating: Ensure the fluid viscosity is correct, the system cooler is functioning, and the pump is not overloaded. Check for restrictions in the discharge line.
• Noise/Vibration: This can indicate cavitation (check suction side), air in the fluid (bleed the system), mechanical wear in bearings or gears, or misalignment between the pump and drive motor. Correct the alignment if necessary.

• Regular Inspection: Perform visual checks for leaks, unusual noises, and overheating.
• Fluid Maintenance: Use clean, recommended fluid and monitor its condition. Regularly check and replace suction and pressure filters.
• Lubrication: Ensure bearings are properly lubricated according to manufacturer specifications.
• Seal and Connection Check: Inspect shaft seals and pipe connections for leaks and tighten or replace them as needed.
• Alignment Check: Periodically verify the alignment between the pump and the drive motor.

Yes, most suppliers and manufacturers offer technical support. For genuine replacement parts (e.g., seals, gears, bearings) and specific troubleshooting guidance for your PGH model, it is recommended to contact the supplier or Bosch Rexroth directly.

Warranty terms can vary by supplier but are often around 60 days for new units. Standard production lead times for MOQ quantities are typically around 15 days, but this can vary based on the product and order size. Always confirm these details with your supplier.
