A rotary circulating pump for heating systems comprises a pump housing with suction and delivery sides separated from one another by an impeller and having a calming or damping chamber situated on the suction side with an integral separator chamber connected thereto for removal of air from the fluid passing through the pump. A flow divider splits the fluid entering into the pump housing into two part flows before they reach the calming chamber. To enhance the separation of air bubbles, the flow divider is so constructed that it imparts to the part flows a rotational motion which is superimposed over their translatory displacement, and deflects the part flows radially as well as axially away from the suction aperture of the pump impeller.
