10 Essential Tips for Maintaining Your Hydraulic Power Unit

A hydraulic power unit (HPU) is the heart of many hydraulic systems, powering critical machinery in industries such as construction, manufacturing, and agriculture. Regular maintenance is essential to ensure that the HPU continues to perform at its best, preventing unexpected breakdowns and costly repairs. Neglecting maintenance can lead to diminished performance, increased energy consumption, and even system failure.

Benefits of Regular Maintenance:

Reduced Downtime: Proactive maintenance helps identify and resolve potential issues before they cause a system failure, minimizing downtime and ensuring that operations run smoothly.

Extended Lifespan: Proper care, such as regular fluid checks, filter replacements, and system inspections, can significantly extend the lifespan of your hydraulic power unit, saving you money on costly replacements.

Improved Efficiency: Keeping the HPU well-maintained ensures that all components, from the pump to the motor, are operating at peak efficiency, which in turn improves overall system performance and energy savings.

Ensuring your hydraulic power unit operates smoothly and efficiently requires more than just occasional checks. At Flowfit, we’ve compiled a list of 10 essential maintenance tips that will help you extend the life of your HPU, prevent costly repairs, and maximize its performance. Ready to keep your system in top shape?

1. Perform Regular Visual Inspections

Early detection of issues can prevent costly repairs.

Check for leaks around hoses, fittings, and seals.

Inspect the condition of the power unit and components for any signs of wear, cracks, or damage.

Look for loose bolts or any signs of instability.

2. Monitor Hydraulic Fluid Levels

Proper fluid levels ensure smooth operation and prevent damage to internal components.

Ensure the hydraulic fluid is at the correct level, as low fluid can affect performance.

Top-up or replace fluids as needed, using the manufacturer-recommended type of hydraulic oil.

3. Change Hydraulic Fluid Regularly

Contaminated fluid can cause damage to the pump, valves, and other components.

Ensure the hydraulic fluid is at the correct level, as low fluid can affect performance.

Top-up or replace fluids as needed, using the manufacturer-recommended type of hydraulic oil.

4. Replace Filters

Clean filters improve system efficiency and prevent damage to sensitive parts.

Regularly check and replace filters to maintain fluid cleanliness and prevent contaminants from circulating.

Use genuine, high-quality filters designed for the system’s specifications.

5. Keep the Unit Clean

Prevents contaminants from entering the system and improves overall operational efficiency.

Keep the hydraulic power unit and surrounding areas free from dirt and debris.

Clean the exterior regularly, especially air intakes and cooling areas.

6. Check and Test Pressure Relief Valves

Overpressure can damage hoses, seals, and pumps, leading to expensive repairs.

Ensure that the pressure relief valve is functioning correctly.

Test regularly to make sure the unit isn’t operating under excessive pressure, which could lead to damage.

7. Inspect and Lubricate the Pump and Motor

Proper lubrication prevents friction and wear, ensuring the longevity of key components.

Ensure the pump and motor are operating smoothly without excessive noise or vibrations.

Lubricate motor bearings and check for any unusual wear on the pump.

8. Monitor System Temperature

Overheating can damage seals and reduce the efficiency of hydraulic systems.

Check the temperature gauge regularly to ensure the system isn’t overheating.

Clean or repair the cooling system (fans, radiators) if necessary.

9. Test System Under Load

This helps identify hidden issues before they cause significant failures.

Periodically test the system under load to ensure it’s running smoothly under real working conditions.

Check for abnormal noise, vibration, or pressure fluctuations.

10. Keep a Maintenance Log

A maintenance log helps you stay on top of required tasks and spot trends that might indicate deeper issues.

Document all maintenance activities, including fluid changes, filter replacements, and inspections.

Track any issues and repairs to identify patterns or recurring problems.
