powerful, rare earth magnets. When the pump is disassembled
(not connected to a motor) and the magnets are exposed, these
magnets produce powerful magnetic fields. individuals with
cardiac pacemakers, implanted defibrillators, other electronic
medical devices, metallic prosthetic heart valves, internal wound
clips (from surgery), metallic prosthetic devices or sickle cell
anemia must not handle or be in the proximity of the magnets
contained inside the pump. Consult a health care provider for
