Suction Filters

The utilisation of HYDAC suction filters is 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, there is no recommendation of ultrafine filtration 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 do not suit for ensuring the protection requirements of components for an economical efficient operation of the system.
