Abstract:
1. A pump comprising: a segmented electro-magnetic array motor, the motor comprising: a stator; a first and a second rotor on opposing sides of the stator; and a pump impeller carried by the first rotor, said impeller integrally formed with said first rotor and extending seamlessly from said first rotor in an axial direction, and the pump further comprising a housing with first and second ends, with the stator carried by and extending into the housing from a point of attachment of the stator with the housing towards the center of the housing and the first rotor and impeller carried by the stator within the housing to eliminate the possibility of water entry, and wherein the housing carries a centrally located electrical input port at one end, wherein the housing carries a fluid inlet at the other end and a pumped fluid outlet located between the electrical input port and the pumped fluid inlet and where the first and second rotors are not mechanically coupled together.
