A pump comprises: at least one rotor rotatable about an axis of rotation; a pump housing surrounding the rotor, wherein a pump channel is formed between a radially inner surface of the pump housing and a radially outer surface of the rotor; and a seal assembly that seals the pump channel to an end surface of the rotor. The seal assembly comprises: a sliding surface which is provided on one of the rotor and the pump housing and which extends perpendicular to the axial direction of the rotor; a static surface provided on the other of the rotor and the pump housing; and a first elastomer element attached to the static surface and pressed against the sliding surface in the axial direction.
