FIELD: pump engineering. SUBSTANCE: blade working wheel of double- sided suction is mounted inside the housing provided with sucking branch pipe and delivery branch pipe. The blades are interposed between the symmetrical disks. The bushing parts of the disks are working for bearings. Electromagnets are mounted inside the housing over the faces of the wheel. The electromagnets are separated from the spaces filled with fluid to be pumped and interact with the permanent ring magnets secured to the radial parts of the disks. The blades are made of a magnetic material. The disks are provided with grooves. The blades are received in the grooves for permitting interaction with the magnets of the disks.
