FAQ:

How can I troubleshoot low or no flow from my PGH pump?

• Check that the reservoir fluid level is adequate.

• Inspect the suction line and inlet filter for blockages or clogs and clean them if necessary.

• Ensure the fluid viscosity is within the recommended range for the operating temperature.

• Check for air leaks in the suction line and ensure all connections are tight.

• Verify that the pump's rotation direction is correct.

• Inspect internal components (gears, shaft seal) for excessive wear.

Q6: How can I resolve issues with low system pressure or pressure fluctuations?

• Internal Leakage: Check for worn gears, pump housing, or side plates, which can cause internal leaks and pressure loss. Replacing worn parts is often necessary.

• System Relief Valve: A malfunctioning or incorrectly set relief valve can cause low pressure. Verify its setting and functionality.

• Fluid Contamination: Contaminated fluid can damage precision surfaces and cause erratic pressure. Check filters and change the fluid if needed.

• Cavitation: As above, cavitation can also cause pressure fluctuations and must be addressed by ensuring proper suction conditions.

Q7: What should I do if the pump is overheating or unusually noisy?

• 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.

Q8: What are the essential maintenance practices for PGH gear pumps?

• 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.

Q9: Can I get assistance with technical issues or order replacement parts?

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.

Q10: What are the typical warranty terms and production lead times?

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.
