PROBLEM TO BE SOLVED: To manufacture a low cost fluid drive pump giving parts general-purpose properties to cope with various specifications. SOLUTION: This pump is provided with two fluid action parts 11 and a connection part 12 connecting the two fluid action parts 11. Each fluid action parts 11 includes an impeller 16, a rotor 17 and a main casing 15. The main casing 15 includes circulation ports 19, 20, an impeller chamber 23, a rotor chamber 25 and a bulkhead 21 dividing the impeller chamber and the rotor chamber. The impeller 16 and the rotor 17 are magnetically joined rotatably as one unit with putting the bulkhead therebetween. The connection part 12 includes a connecting shaft interlocking and connecting each rotor 17 and a connection casing 32 connecting each main casing 15. One fluid action part 11 constructs a motor part M rotating the impeller 16 by fluid and transmits rotation power to the connecting shaft 33 via the rotor 17. Another fluid action part 11 constructs a pump part P rotating the impeller 16 by rotating power from the connecting shaft 33 via the rotor 17. COPYRIGHT: (C)2007,JPO&INPIT
