Abstract

The invention relates to a separation pump (1) for pumping a fluid mixture (2) of gas (3) and liquid or suspension (4) and for separating gas (3) and liquid or suspension (4) from each other. The separation pump (1) comprising a rotatable drum means (10) for rotating fluid mixture (2). The rotatable drum means (10) having an inner wall (11) and an inner space (12). The rotatable drum means (10) being rotatable for causing liquid or suspension (4) of fluid mixture (2) to form a layer of liquid or suspension (4) on the inner wall (11) and for causing gas (3) of the fluid mixture (2) to migrate towards the axis of rotation (13). The separation pump comprises foam discharging means (15) for discharging foam (16) from the inner space (12) of the rotatable drum means (10). The foam discharging means (15) comprises a second outlet (17).
