ABSTRACT:
A seamless pump is disclosed which includes a pump casing that houses a stator and a rotor. The stator and rotor provide enhanced pumping action in the seamless pump. The stator surrounds at least a portion of the rotor. A rotatable housing surrounds at least a portion of the pump casing and is operatively connected to the motor. A plurality of first magnets are located about an interior surface of the housing and are rotatable therewithin and a plurality of second magnets are operatively connected to and rotatable with the impeller. A seal isolates the second magnets from material being pumped by the pump. A cooling jacket may be used to cool the pump.
