Summary:PROBLEM TO BE SOLVED: To provide a pump eliminating a need for a flow passage switch part such as a solenoid valve at a control part for a fluid pressure and use magnetic fluid the fluid pressure of which is controllable. SOLUTION: In this pump, a passage 7, comprising a first magnetic pole 2 consisting of a rotary cylinder body having recessed parts formed in an outer periphery in parallel to a rotary shaft at intervals; and a second magnetic pole 6 arranged on the body side, is filled with a magnetic fluid 10. A magnetic field is exerted on the magnetic fluid through the magnetic pole. Through rotational drive of the first magnetic pole 2, the magnetic fluid 10 attracted between the magnetic poles is delivered and the magnetic fluid is utilized as working liquid.
