The invention provides a volute pump head for an artificial heart. The volute pump head comprises a volute, wherein the volute comprises a blood inlet and a blood outlet; the volute is internally provided with a fixing shaft; the fixing shaft is sleeved by a magnetic body; a conical impeller of an opening structure is mounted on the outer side of the magnetic body; when the magnetic body is rotated, the conical impeller is driven to rotate; a first gap is formed between the fixing shaft and the magnetic body; and when the conical impeller is driven to rotate by the magnetic body, a part of blood flows upwards through the first gap, and the conical impeller is suspended in the blood. The invention further provides an artificial heart pump and (extracorporeal membrane oxygenation) equipment.According to the pump head for the artificial heart provided by the invention, due to height and inclination designing of a first blade and a second blade, sufficient washing can be benefited, and thrombus and blood cell damage can be reduced; and due to designing of the conical impeller and the fixing shaft in the volute, heat can be effectively reduced, thrombosis can be reduced, and blood celldamage can be effectively avoided.
