Suction Filter

What is a suction filter?

A suction filter is a vital component of the hydraulic system.

Its function is to protect the hydraulic pump by preventing solid particles, contaminants (dirt and impurities) present in the fluid from reaching the pump.

It is installed at the pump’s suction inlet, filtering the fluid before it enters the pump to be pressurized and distributed throughout the system.

Types of Suction Filters:

There are different types of suction filters, which may vary according to the application and type of hydraulic fluid.
  • Metal mesh filters (or screen filters): Used in hydraulic systems where the fluid has low dirtiness (less impurities).
  • Cartridge filters: Greater particle retention capacity, ideal for systems with more contaminated (dirty) fluids.
  • Synthetic or mixed media filters: Used in systems that require high filtration precision, offering a greater retention capacity for small particles.

Correct application

It is important to ensure that the suction filter is compatible with the type of fluid used and the operating conditions of the hydraulic system. Incorrect applications can compromise the functioning of the system and accelerate component wear.

A filter with a capacity that is too small can clog quickly, while a filter that is too large may not be effective in terms of filtration efficiency and may increase operating costs. The correct dimensioning depends on the system flow, the amount of contaminants in the fluid and the type of pump.

Importance of the filter

The main function of the suction filter is to protect the hydraulic system. Without the filter, contaminant particles, such as “dirt”, rust or other debris, can damage the pump and other components of the hydraulic system.

This can result in premature wear of the hydraulic components, especially the pump.

The filter ensures that the fluid is clean and free of contaminants, which increases the life of the system and reduces maintenance and repair costs.

Preventive Maintenance and Inspection of the Suction Filter:

Preventive maintenance of the suction filter is crucial to ensure that it continues to function properly. Some recommended actions include:
  • Pressure check: A drop in pressure between the filter inlet and outlet is a sign that the filter may be saturated or “clogged”.
  • Visual inspection: Regularly inspect the filter to detect the need for replacement.

What happens if the filter is not replaced

If the suction filter is not replaced, it can become saturated and “clogged” and lose its efficiency.

Allowing solid particles and impurities to enter the hydraulic pump, resulting in wear, failure of the pump, valves, pipes and other components of the hydraulic system.

The obstruction (clogging) of the filter causes a drop in the pressure of the hydraulic system, which affects the functioning of the system, leading to catastrophic failures, generating high costs with maintenance and replacement of parts.

Preventative maintenance of your equipment is essential to ensure the performance and durability of the hydraulic system by always replacing the suction filter.

Corrective maintenance can cost between R$5,000.00 and R$20,000.00 for a hydraulic pump.

What is the replacement period?

The replacement of the suction filter may vary depending on the application, type of fluid and work environment.

The filter should be checked and replaced periodically every 6 months to 1 year, or according to the manufacturer’s recommendations.

In environments with severe use or with highly contaminated fluid, replacement may be necessary more frequently.

Preventive maintenance is essential to ensure the proper functioning of the filter and the hydraulic system.
