Zusammenfassung:	FIELD: mechanical engineering. SUBSTANCE: plant has housing and cover which forms flow-through chamber brought in communication with inlet and outlet of pump; rotor mounted on sliding rotation support is located in this chamber; rotor is made in the form of two discs; pumping plant is also provided with stator located between discs and pressed between cover and housing and impeller secured to one of discs. Magnets of alternating polarity and magnetic circuit rings are built in discs of rotor. Control is effected by means of rotor position sensor through electronic switch. Electromagnetic coils are built in stator; similar coils may be provided with built-in permanent magnets which may be arranged on rotor irregularly. In this case, use is made of single-phase motor and single electronic switch. Possibility of arranging the pump and electric motor in flow-through chamber increases power and productivity, enhances efficiency without increase of volume. EFFECT: simplified construction and low cost.
