2. Check for Temperature Variation

A quick hands-on inspection (only if conditions are safe) can reveal potential issues. Typically:

Fluid side → warmer

Gas side → cooler

If both sides feel similar, it may signal gas loss or a damaged bladder—both requiring immediate attention.

3. Use the System Pressure Gauge for a Quick Estimate

This simple method gives you a rough pre-charge reading without special tools:

Shut down the system

Allow hydraulic fluid to drain

Watch the gauge — the last reading before dropping to zero approximates your pre-charge

This is a convenient way to catch early signs of pressure deviation.

4. Measure with a Check/Charge Head

For precise and reliable results, a check/charge head is the best option. It connects directly to the accumulator’s gas valve, allowing you to:

Read nitrogen pressure accurately

Adjust or refill as necessary

This tool helps prevent downtime and extends accumulator service life.

🔧 Pro Tip: Maintain a Service Record

Logging every inspection, pressure reading, and adjustment helps you identify trends and schedule preventive maintenance before failures occur.

4 Ways to Check Your Hydraulic Accumulators for Maximum Production

Hydraulic accumulators play a critical role in maintaining efficiency and reliability across many industrial systems. Think of them like the hydraulic version of a capacitor in an electrical circuit—they store and release energy in the form of pressurized hydraulic fluid. This keeps your system running smoothly, absorbs shocks, and helps regulate pressure even under tough conditions.

At FEC International, we specialize in delivering high-performance, reliable hydraulic accumulators for a wide range of industrial applications. But no matter how durable your equipment is, regular check-ups are essential to ensure optimal performance and longevity.

Not sure where to start? Here are four easy and effective ways to check your hydraulic accumulator’s health:

1. Check the Pre-Charge Pressure

Every accumulator is pre-charged with dry nitrogen—usually between 50–66% of your system’s maximum working pressure. For example, if your system operates at 1500 PSI, your pre-charge should be somewhere between 750–1000 PSI.

If the pre-charge is too low, it can lead to poor fluid delivery. Too high? You risk pressure spikes. Both scenarios can compromise system performance and safety.

2. Feel for Temperature Differences

Here’s a quick physical test: carefully touch the accumulator (ensure it’s safe to do so). Normally, the fluid side of the unit will feel warmer than the gas side.

If both sides feel the same, it could indicate a gas leak or a damaged bladder, meaning it's time for immediate inspection.

3. Use the System Pressure Gauge

Want a fast way to estimate pre-charge pressure without any tools? Try this:

Turn off the system

Allow the fluid to drain

Watch the gauge—the last reading before it drops to zero is roughly your pre-charge pressure

It’s a simple trick that can help you keep tabs on accumulator performance between full maintenance checks.

4. Use a Check/Charge Head

For a more accurate approach, use a check/charge head. This tool connects directly to your accumulator’s gas valve, allowing you to:

Monitor nitrogen pressure precisely

Refill as needed

It's a small investment that helps you avoid major downtime and costly failures.

🔧 Bonus Tip: Keep a Maintenance Log

Documenting your maintenance checks is a great habit. A simple logbook can help you track trends, spot early issues, and schedule preventative service.

At FEC International, we offer a full line of premium accumulators, spare parts, and maintenance tools to help your hydraulic systems operate at peak efficiency. Whether you're building a new system or maintaining an existing one, we're your trusted hydraulic partner.

4 Ways to Check Your Hydraulic Accumulators for Maximum Production

Hydraulic accumulators play a vital role in many industrial systems, acting as energy storage devices that improve efficiency, absorb shocks, and ensure smooth hydraulic operations. Think of them as the hydraulic equivalent of capacitors in an electrical circuit—they store and release hydraulic energy to stabilize system performance and maintain pressure when it's needed most. At FEC International, we specialize in delivering reliable and high-performance hydraulic accumulators for a wide range of industrial applications. Like any critical component in a hydraulic system, regular inspection and maintenance of accumulators are essential to maximizing uptime, productivity, and service life. In this article, we’ll walk through four practical and effective methods for checking your hydraulic accumulators and ensuring they operate at peak performance.

Check the Pre-Charge Pressure One of the most important maintenance tasks is checking the pre-charge pressure of your hydraulic accumulator. Whether it's a bladder, piston, or diaphragm type, maintaining the correct pre-charge is crucial for proper functionality. Accumulators are typically pre-charged with dry nitrogen gas to around 50% to 66% of the maximum system pressure. For instance, if your hydraulic system operates at 1500 PSI, the accumulator should be pre-charged to somewhere between 750 and 1000 PSI. This pre-charge is the gas pressure on the nitrogen side of the accumulator when the hydraulic fluid is fully discharged. If the pressure is too low, the accumulator won’t function properly—delivering less fluid volume and potentially allowing damaging pressure spikes. On the flip side, too high a pre-charge can prevent fluid from entering the accumulator altogether. Routine checks of pre-charge pressure should be a standard part of any preventive maintenance program to prevent unnecessary wear and potential system failure.

Monitor Temperature Differences Another tell-tale sign of accumulator health is the temperature difference between the fluid side and the gas side. In a properly functioning system, you’ll typically notice that the fluid end is warmer than the gas end. This occurs due to hydraulic fluid friction and the heat it generates during pressurization and flow. However, if the entire accumulator shell maintains a uniform temperature, that’s a red flag. It could indicate a ruptured bladder, nitrogen gas leakage, or an incorrect pre-charge level—all of which compromise performance. While temperature checks aren’t a standalone diagnostic tool, they can serve as a valuable visual or thermal cue that something might be wrong internally.

Use the System Pressure Gauge Did you know you can perform a quick pre-charge check using your system’s pressure gauge—without any extra tools? Here’s how: Shut down the hydraulic system.

Activate the manual or solenoid valve (if installed) to allow the fluid to flow back to the reservoir.

Watch the system pressure drop.

The last pressure reading before it drops to zero generally reflects the accumulator’s gas pre-charge pressure. While this isn’t the most accurate method, it’s a useful quick check that can help you detect major issues like total gas loss or system imbalance. If the observed value is significantly off from the expected pre-charge, it may be time for a full inspection.

Utilize a Check/Charge Head For the most accurate and reliable reading, professionals rely on a check/charge head. This tool threads directly onto the accumulator’s gas valve and displays the pre-charge pressure on a built-in gauge. Many check/charge heads are designed not only for monitoring but also for charging accumulators using nitrogen bottles. These tools are invaluable for conducting routine inspections and topping off gas levels as needed. If you're building a preventive maintenance kit or managing a fleet of hydraulic machines, a check/charge head is a must-have. You can browse our range of check/charge kits at FEC International — your trusted partner for hydraulic accumulator systems, service tools, and accessories.

Additional Indicators of Accumulator Malfunction Aside from the four checking methods above, it's important to be alert to behavioral signs that something might be wrong with your accumulator. These can include: Slower cylinder cycle times

Excessive system noise

Rapidly cycling pump unloaders

Pressure fluctuations in the hydraulic lines

Any of these symptoms can point to internal damage, a gas leak, or a ruptured bladder. A skilled hydraulic technician can often diagnose and resolve these issues quickly using one or more of the techniques outlined above.

Pro Tip: Create a Maintenance Log Implementing a routine maintenance schedule can save time, money, and hassle in the long run. Log each inspection date, the observed pre-charge pressure, and any maintenance performed. This historical data can help spot trends or gradual degradation, allowing you to plan proactive repairs before they become critical.

Conclusion Hydraulic accumulators are integral to system efficiency, shock absorption, and fluid delivery. Neglecting their maintenance can lead to system failure, reduced productivity, and increased costs. By regularly applying these four checking methods—pre-charge inspection, temperature monitoring, pressure gauge observation, and using a check/charge head—you’ll ensure your accumulators perform at their best.

Bladder Accumulators for Efficient, Stable, and Shock-Resistant Hydraulic Systems

In today's world of advanced machinery and automation, hydraulic systems play a vital role across industries — from manufacturing and agriculture to aerospace and construction. These systems rely on precise control, reliable energy delivery, and stability under pressure. One key component that ensures all of this — and more — is the bladder accumulator. What Is a Bladder Accumulator? A bladder accumulator is a type of hydraulic accumulator that stores energy in the form of pressurized fluid. It features a flexible bladder inside a pressure vessel, typically made of high-strength steel. The bladder separates the gas (usually nitrogen) from the hydraulic fluid. As fluid enters the accumulator, it compresses the gas, storing potential energy that can be released when needed. This compact yet powerful device serves multiple critical functions within a hydraulic system — helping improve efficiency, stabilize pressure, absorb shocks, and support system responsiveness. How Bladder Accumulators Improve Hydraulic Systems

Pressure Stabilization Hydraulic systems are dynamic — pressure can fluctuate due to load changes, pump pulsations, or sudden valve movements. These fluctuations can negatively affect system performance and wear out components over time. A bladder accumulator helps to buffer these pressure variations, ensuring smoother operation and extending the life of valves, pumps, and other hydraulic parts.

Shock and Vibration Absorption In industrial or mobile equipment, sudden directional changes or load spikes can lead to hydraulic shock (also known as water hammer). Left unmanaged, these shocks can cause serious damage. Bladder accumulators act like hydraulic cushions, absorbing these shocks and reducing vibration. This not only protects the system but also enhances operator comfort and machine reliability.

Emergency Power Source In the event of pump failure or power loss, a bladder accumulator can provide temporary hydraulic power. It discharges the stored fluid to allow controlled machine shutdown or to complete a critical operation safely. This is especially important in systems where safety and continuity are crucial — such as in aircraft or heavy construction equipment.

Leakage and Thermal Compensation Even the most tightly sealed hydraulic systems can lose fluid over time due to minor leaks or thermal expansion and contraction. A bladder accumulator compensates for these changes automatically, maintaining system pressure and performance without requiring constant manual adjustment.

Energy Efficiency and Cost Savings Bladder accumulators help optimize energy use by storing surplus hydraulic energy during low-demand periods and releasing it during peak demand. This reduces the load on the pump, minimizes energy consumption, and leads to lower operating costs. It also allows for the use of smaller pumps and motors in some systems, reducing capital investment and improving overall efficiency. Why Choose FEC’s Bladder Accumulators?
