Filteranordnung und ein Verfahren zur Herstellung einer Filteranordnung

WO 2010102961 A1 UPAB: 20101002 NOVELTY - The pump has a filter arrangement comprising two outflow paths (110, 120) and a hydrophilic membrane filter (150) arranged between an inflow path (105) and one of the outflow paths. A section of another hydrophobic membrane filter (140) and a section of the latter filter lie opposite to each other at a distance (d) of not more than 1 mm, so that a gas bubble (210) moving with a medium (220), which flows in the inflow path, is in contact with the latter hydrophobic membrane filter during the movement. The outflow paths of the filter arrangement are connected to a suction side of the pump. USE - Pump for pumping a medium i.e. water, from a suction side to a pressure side. ADVANTAGE - The outflow paths of the filter arrangement are connected to the suction side of the pump, thus filtering a particle from the medium with the gas bubble independent of orientation of the filter arrangement, without guiding the gas bubble for increasing flow resistance
