Abstract

The invention relates to a pumping unit, which comprises an electric motor (11) and a liquid ring pump (1) driven by the latter via a belt (10), in which unit the electric motor (11) is mounted on the housing parallel to the longitudinal axis of the liquid ring pump (1) by means of a carrier plate (9) fixed on the top of the housing (2) of the liquid ring pump (1). A pump unit of this type requires a small installation area and can be constructed at the works ready for installation. <IMAGE>
