Suction Filters

HYDAC suction filters are used for functional protection of the downstream pump in the circuit (although only for the avoidance of coarse contamination). In order to avoid cavitation in the pump, which means negative pressure and a sudden pump failure, no ultrafine filtration is recommended at this point in the system.

Due to the risk of pump cavitations, relatively coarse filter materials with a filtration rating of > 25 μm are used. Therefore, suction filters are not suited for ensuring the required protection of components for an economical efficient operation of the system.
