Hydraulic systems power modern industry. They can also use a lot of energy. In some cases, they can make up to 30% of a factory’s electricity bill. The good news is that you can save energy with your system right now. There are proven strategies that can help you save energy and money.

Industrial managers, facility operators and engineers who care about sustainability: here are 5 methods to help you cut energy waste, boost efficiency and support your green goals.

Switch to Variable Speed Drives (VSD)

The biggest impact you can make is to replace fixed-speed pumps with VSDs. These VSDs adjust motor speed to match the demand.

• How it works: Pumps only run as fast as they need to. They don’t over-. Run at full speed all the time.
• Energy Savings: You can reduce pump energy use by 20-50%.
• Quick Win: Many VSDs pay for themselves in 12-18 months by saving electricity.

Try This Today: Check your pump runtime versus the load. VSDs work in systems with variable demand.

Optimize Accumulators for Peak Shaving

Use accumulators to store energy during low-demand periods. Then release it during peak loads.

• Benefits: This reduces pump cycling, smooths out pressure spikes and cuts energy peaks.
• Savings: You can lower energy consumption by 15-25% in operations that’re intermittent or cyclic.
• Pro Tip: Make sure to size accumulators for your specific duty cycle. Oversized ones waste space, and underutilized ones don’t work well.

Upgrade to Efficient Hydraulic Fluids

Switch from mineral oils to synthetic or bio-based fluids. These fluids have lubricity and viscosity index.

• Why it works: They reduce friction, work better in cold and hot temperatures and reduce pump strain.
• Results: You can save 5-10% on energy and extend the life of your components.
• Interactive Check: Calculate your fluid change ROI. Many people see payback in under a year.

Implement Load-Sensing Controls

Load-sensing pumps automatically adjust output pressure to match the work requirement.

• Key Advantage: You don’t need to maintain system pressure when only partial power is needed.
• Energy Impact: You can save 20-40% on energy in pressure applications like presses and injection moulding.
• Easy Upgrade: Modern electronic load-sensing kits can retrofit existing systems.

Regular Maintenance = Energy Savings

Clean, leak-free and properly tensioned systems are naturally more efficient.

Focus Areas:

• Fix leaks (they waste 10-20% of energy)
• Filters and heat exchangers
• Check valve settings and cylinder alignment
• Monitor fluid condition monthly

Quick Audit Checklist:

• Leak inspection (hoses, fittings, cylinders)
• Filter condition check
• Pressure gauge calibration
• Fluid analysis report review

Energy Savings Action Plan

Start Here: Pick one method based on your biggest energy waste area:

• High pump runtime? – VSDs
• Cyclic loads? – Accumulators
• High-pressure apps? – Load sensing
• Basic maintenance gaps? – Start with leaks and filters

Expected Results: Most facilities see 15-30% energy reduction within the first year.
