FlowFilter double strainer is planned especially for the objects that are using high concentration of humus water or another kind of water with small particles. The meter can be used with quench-rinsed seals, packings seals, single mechanical seals, or mechanical seals. It has compact filter construction where is combined FlowUnit seal water control unit.

In the double strainer unit the filter can be changed and cleaned without interrupting the water flow to the strainer unit or to seal. The flow rate can be directed alternatively through two filters so the object is always receiving filtered seal water. The great advantage of FlowFilter operation idea is opportunity to allow service or filter change without need for stopping the flow.
