Abstract
A single-stage centrifugal pumping unit comprises a double entry pump with a housing, which consists of a base and a cover, manifolds, a rotor, and a volute. The volute is configured in the form of a separate, independent component. Parts of the outside surface thereof, which are intended to be accommodated in cradles provided for this purpose in the cover and the housing, correspond to the shape of the surfaces of said cradles. An impeller and the volute are replaceable as a pair. The parameters of the impeller and the volute in each pair are calculated to provide maximum efficiency while ensuring the requisite feed and pressure. The invention is directed toward providing a pumping unit which demonstrates peak efficiency in non-nominal modes while having a simplified design and being universal in nature.
