This invention relates to a pump for discharging a fluid and, more particularly, to pump of the type in which a fluid is easily sucked and discharged by an impeller (11) having a cylindrical frame (16), a magnetic material (10) embedded in outer periphery thereof, and a vane (17) arranged inside the cylindrical frame (16), wherein rotation is imparted to the impeller (11) by magnetic cooperation of the magnetic material (10), such as a permanent magnet, and an electromagnet disposed in a housing (2). The pump according to the invention can increase the discharge capacity by provision of an auxiliary impeller (13) disposed on the front and/or rear of the impeller (11). Moreover, the pump according to the invention makes it possible to offer the convenience in use and storing with the simplified construction, and to facilitate the disinfection and cleaning of the pump, and exchange of components thereof. |
