Fluid pump systems for use in an open loop or closed loop system driven by a motor that does not impede the flow of fluid being pumped are disclosed. A first fluid pump system includes an in-line direct drive motor. The rotor (46, 48) and stator (44) of the motor are positioned about an axis of fluid flow so as not to impede the fluid flow. A second fluid pump system includes an off-line indirect drive motor. The fluid being pumped is driven by an impeller (56) coupled to the inside wall surface of a rotatable member (50) and the outside wall surface of the rotatable member is driven by a motor external to the fluid flow. The motor parts (46, 48) are fully integrated with the pump rotor (56) to drive the pump, therein reducing the number of component requirements, and increasing pump efficiency. |
