Suction filtering elements are installed upstream of the hydraulic pump to protect the circuit from solid contaminants coming from the reservoir. While modern filtration strategies often favour less restrictive solutions such as the return filter or pressure filtration, suction filters are still widely used thanks to their ability to capture impurities right at the pump inlet.

They are especially recommended when it is not possible to ensure a perfectly clean reservoir or when the risk of initial contamination is high. To maintain effective filtration capacity without compromising pump supply, it is essential to select elements with low pressure drop and suitable flow capacity.

Suction filtering elements can be manufactured with:

• Surface filtration media (wire mesh, perforated plates, Dutch weave screens), easily cleanable by washing or reverse air flow.

• Depth filtration media (synthetic fibres, sintered metals), capable of retaining very fine particles through impact and adhesion.

Our range includes solutions compatible with the main industry standards, designed for reliability, mechanical strength, and long service life, even in demanding operating conditions.

For optimal system protection and monitoring, the suction filter can be integrated with:

• Pressure filtering elements to remove residual contaminants in-line, even at high pressures.

• Return filtering elements to trap impurities before the fluid returns to the reservoir.

• Clogging indicators to monitor the filtering element’s saturation status in real time and prevent efficiency loss.

Choosing the right suction filtering element ensures safe pump supply, reducing the risk of cavitation, premature wear, and unexpected failures. Browse the full filtering elements section for a complete overview of all available types, or explore the entire range of hydraulic filters.
