    Abstract: A pumping heart simulator is described. The pumping heart simulator can include an inflow pump, an outflow pump, and a control apparatus. The inflow pump can have a first magnetic motor that facilitates flow of fluid from a bottom portion of a fluid reservoir to three inlet valves of a heart via the inflow pump. The outflow pump can have a second magnetic motor that facilitates flow of fluid from two outlet valves of the heart to a top portion of the fluid reservoir via the outflow pump. The control apparatus can alternately activate the first magnetic motor and the second magnetic motor. Related apparatuses, systems, methods, techniques and articles are also described.
