FIELD: medicine.
SUBSTANCE: invention concerns a micropump system, particularly a micropump system for medical application. A pump comprises a rotor (6) comprising a motor section (34), first and second axial expansions (14, 16) having different diameters, a stator (8) comprising a stator housing, having a rotor chamber (10, 12) for receiving at least the axial expansions, and first and second seals (18, 20) fixed around the first and second axial expansions. The axial expansions are provided with fluid grooves interacting with respective first and second seals to form first and second valves, which open and close fluid propagation along the respective seal as a function of at least rotor angulation. The pump comprises a third seal fixed around the second axial expansion nearby the motor section (34) of the rotor and limiting an output section (12) of the rotor chamber.
EFFECT: invention aims at creating the pump for medical application, which is expected to be accurate, reliable, space-saving and safe to use.
