Hydraulic filtration

To ensure the level of fluid cleaning in the hydraulic systems, these are equipped with filters retaining undesirable particles that can be generated within the system during the installation and operation phase. Filters are generally characterized by the quantity of particles they can retain and the minimum size of these particles. There are different types of filters: suction, return, pressure, spin-on... Filters can be complete with clogging indicators: sensors that react when a pressure value is reached in the filter, possibly differential. Under these conditions and depending on the type of clogging indicator installed a visual signal appears or an electrical contact is activated, allowing an immediate replacement of filter element.

Filter elements

Filter elements

The cartridge constitutes the actual filter element of a filtration system. It can be made up of different materials and with different degrees of filtration depending on the requests and applications.

Air filters

Air filters

The air filters are used for the filtration of the air entering the tanks of the hydraulic systems and for the oil filling.

Spin-on filters

Spin-on filters

Spin-on filters are used for the safety of individual process components, for example pumps, valves ... In spin-on filters the cartridge includes a filter element contained within a fixed metal container to the filter head.

Suction filters

Suction filters

Suction filters in hydraulic systems are installed to protect the pumps from gross contamination that can compromise their operation.

High pressure filters

High pressure filters

The pressure filter is installed on the pressure lines of the hydraulic systems; they consist of closed containers pressurized capable of withstanding process pressures.

Accessories

To maintain the efficiency of the filters it is necessary to avoid clogging phenomena by using appropriate indicators. These devices switch when the clogging of the filter causes an increase in pressure drop across the filter element. The indicator is set to an alarm before the element is completely clogged, warning of the need for replacement.

Return filters

Return filters

Return filters filter the fluid returning to the tank and prevent solid particles from entering the system that typically form due to component wear.
