Optimal protection
of your pump

Application:

Suction filters are required for protection of the downstream hydraulic-pump from coarse contamination, mainly due to lack of initial cleaning or to an accidental ingression.

They take care of the pump, ensuring a safe and efficient operation.

The Suction Filters must be always properly sized to avoid cavitation of the pump.

Please note that the general cleanliness level required by the system must be ensured by the filters having that function (Return or Pressure fiIters).

User Benefits:

Suction filters represent the “first-line” filtration and are used to:

  • avoid the ingress of contamination into the hydraulic circuit
  • prolong the lifetime of finer downstream filtration
  • reduce the particulate-load on the finer filter, thus extending servicelife-intervals, unplanned downtime and maintenance
  • avoid damage to the finer downstream filter from coarse particulate, such as rust.

The overall consequence of effective “first-line” suction filtration is a reduction in the Kwh running costs of the hydraulic-pump.
