FIELD: engines and pumps.
SUBSTANCE: invention is related to machine building and may be used in systems of temperature control of aviation and rocket engineering products. Doubled electric pump unit comprises body, two centrifugal electric pumps installed in it, inlet cavities of which communicate to inlet nozzle, and outlet cavities communicate to outlet nozzle via double-sided check valve in the form of disc with switching element inserted in its opening. On internal surface of body through boring there are two grooves, every of which communicates outlet of one of centrifugal electric pumps with double-sided check valve. Disc is installed in through boring of body with their ends support against ends of centrifugal electric pumps.
EFFECT: increase of anti-cavitation properties without rise in dimensions.
