In the world of heavy equipment, maintaining the hydraulic system is essential to ensure smooth operation and prevent costly repairs. One critical component of the hydraulic system is the hydraulic tank strainer, which plays a vital role in keeping the hydraulic fluid clean and free from contaminants. The strainer filters out debris and particles from the hydraulic fluid before it circulates through the system. Over time, dirt, metal shavings, and other contaminants can accumulate in the strainer, causing it to become clogged or inefficient. In this article, we’ll explore the importance of hydraulic tank strainers, common issues related to them, and how to maintain them effectively.
Importance of Hydraulic Tank Strainers
Hydraulic systems are the backbone of many heavy machines, powering everything from lifting arms to attachments and even steering. The hydraulic fluid that circulates throughout the system must remain clean to avoid damaging sensitive components like pumps, valves, and motors. The hydraulic tank strainer, which is typically installed inside the hydraulic reservoir, helps to filter out any foreign particles that may have entered the system.
A clean hydraulic tank strainer ensures that the hydraulic fluid is free of contaminants, allowing the system to work efficiently. However, if the strainer becomes clogged, the fluid may not flow as smoothly, resulting in poor performance and potential damage to other components of the hydraulic system.
Signs of a Clogged or Faulty Strainer
If the hydraulic tank strainer is not functioning properly, it can lead to a variety of issues that can affect the performance of the heavy equipment. Some common signs of a clogged or faulty strainer include:
1. Decreased Hydraulic Power: If the hydraulic fluid is not flowing efficiently, the machine may exhibit slower or weaker performance. This can manifest as slow lifting or tilting of the bucket, or the inability to operate attachments effectively.
2. Overheating: When the hydraulic fluid is not circulating properly due to a clogged strainer, the pump can overheat. This is because the pump is working harder to move the fluid through a restricted system, which can lead to increased wear and tear on the pump.
3. Unusual Noises: A struggling hydraulic system can produce unusual noises, such as whining or grinding sounds, which often indicate that the fluid is not circulating as it should.
4. Increased Pressure: A clogged strainer can cause excessive pressure within the hydraulic system. The system will need to work harder to achieve the desired lifting force or movement, which can strain the pump and cause it to fail prematurely.
5. Fluid Contamination: If the strainer is no longer effective at filtering debris, contaminants may start to circulate through the system, potentially causing damage to other components like valves, cylinders, and hoses.
How to Maintain and Clean a Hydraulic Tank Strainer
Proper maintenance of the hydraulic tank strainer is essential to prolong the lifespan of the hydraulic system and ensure optimal performance. Regular checks and cleaning can prevent clogs and ensure that the system is running smoothly. Here are the steps to maintain and clean the hydraulic tank strainer:
1. Regular Inspections
Inspect the hydraulic fluid regularly to ensure it is clean and free from debris. This can be done by checking the fluid’s color and consistency. Hydraulic fluid should be clear and free from contaminants. If the fluid appears cloudy or has particles floating in it, it may be time to clean the strainer.
2. Cleaning the Strainer
To clean the hydraulic tank strainer, follow these steps:
If the strainer has become too clogged or damaged to clean properly, it is important to replace it. A new strainer will ensure that the hydraulic fluid remains clean and free of contaminants. Always use a replacement strainer that matches the specifications of the original part.
4. Refill with Clean Hydraulic Fluid
Once the strainer is cleaned or replaced, refill the hydraulic reservoir with fresh hydraulic fluid. Make sure the fluid is the correct type and meets the manufacturer’s specifications for the machine. Using the wrong fluid can cause damage to the hydraulic system and reduce efficiency.
5. Test the System
After reassembling the strainer and refilling the fluid, test the hydraulic system to ensure it is functioning properly. Monitor the machine for any signs of sluggish movement, overheating, or unusual noises that could indicate an issue with the strainer or the hydraulic system.
Tips for Prolonging the Life of the Hydraulic Tank Strainer
The hydraulic tank strainer is a small but crucial component in a heavy equipment hydraulic system. It helps keep the hydraulic fluid clean, preventing debris from damaging the pump, valves, and other parts. Regular maintenance, such as inspecting, cleaning, and replacing the strainer when necessary, is essential for preventing costly repairs and ensuring the longevity of the hydraulic system. By taking care of this vital component, operators can enjoy reliable performance and avoid unexpected downtime due to hydraulic issues.

2. Cleaning the Strainer
To clean the hydraulic tank strainer, follow these steps:
- Drain the Hydraulic Fluid: Before accessing the strainer, it is necessary to drain the hydraulic fluid from the reservoir. This can be done by opening the drain valve or using a suction pump to remove the fluid. Always dispose of the fluid according to local regulations.
- Locate the Strainer: The hydraulic tank strainer is typically located inside the hydraulic reservoir. It may be attached to the tank’s internal baffle or placed directly in the fluid line.
- Remove the Strainer: Carefully remove the strainer from the tank. Depending on the design, it may be secured with bolts or clips. Take note of its placement for reinstallation.
- Clean the Strainer: Once the strainer is removed, clean it thoroughly with a soft brush and solvent to remove any dirt, debris, or buildup. Avoid using harsh chemicals that could damage the strainer or other components.
- Check for Damage: Inspect the strainer for any signs of damage, such as holes, cracks, or excessive wear. If the strainer is damaged, it should be replaced with a new one.

Tips for Prolonging the Life of the Hydraulic Tank Strainer
- Use High-Quality Fluid: Always use high-quality hydraulic fluid that is appropriate for the machine’s operating conditions. Low-quality fluid can contain impurities that clog the strainer more quickly.
- Change Fluid Regularly: Change the hydraulic fluid at regular intervals, as recommended by the manufacturer. Old, contaminated fluid can cause strain on the system and reduce the effectiveness of the strainer.
- Monitor Operating Conditions: Keep an eye on the machine’s operating conditions. Excessive heat, pressure, or heavy-duty use can cause the hydraulic fluid to break down faster, leading to increased wear on the strainer.
- Install a Secondary Filtration System: Some operators choose to install a secondary filtration system that helps remove smaller particles from the hydraulic fluid, extending the life of the tank strainer and other components.
