Pump having a filter arrangement

The invention relates to a pump for pumping a medium from a suction side to a pressure side, comprising a filter arrangement. The filter arrangement comprises an inflow path (105), a first outflow path (110), and a second outflow path (120). A hydrophobic membrane filter (140) is arranged between the inflow path (105) and the first outflow path (110). A hydrophilic membrane filter (150) is arranged between the inflow path (105) and the second outflow path (120). At least one section of the hydrophobic membrane filter (140) and one section of the hydrophilic membrane filter (150) lie across from each other at a distance (d) of no more than 1 mm so that a gas bubble (210) that moves with a medium (220) flowing in the inflow path (105) comes into contact with the hydrophobic membrane filter (140) during the movement. The first and second outflow paths (110, 120) of the filter arrangement are connected to the suction side of the pump.
