FIELD: engines and pumps.
SUBSTANCE: proposed duplicated electric pump unit relates to power engineering and can be used in temperature control systems of products of aircraft and rocket engineering. The duplicated electric pump unit includes a housing assembly and two centrifugal electric pumps installed in the housing on its opposite ends. An outlet cavity of each electric pump is interconnected with an outlet branch pipe through a transfer groove and a T-shaped channel of a two-way check valve. The internal part of the housing is made in the form of a circular cylinder with outside diameter equal to diameter of a through bore of the external part of the housing; from each end face of the circular cylinder there is a bore for arrangement of one of electric pumps, and the T-shaped channel of the two-way check valve is made in a connection strap between two bores, and its axis crosses the housing longitudinal axis.
EFFECT: invention is aimed at reduction of hydraulic resistance without any increase in dimensions.
