FIELD: engines and pumps.
SUBSTANCE: invention relates to machine building and can be used in thermal control systems of aerospace engineering. Proposed pump unit comprises built-up housing to accommodate two centrifugal pumps mounted at opposite sides, pump inlets being communicated with inlet pipe. Outlet of every pump communicates with outlet via transfer groove and T-shape channel of two-way check valve. Housing inner part is composed of circular cylinder, its OD being equal to housing outer part through bore diameter. Bore is made on circular cylinder every end to receive one of electrically driven pumps while T-shape channel is made in the web between two bores.
EFFECT: lower drag.
