FIELD: engines and pumps.
SUBSTANCE: house water station (1) has motor (8) and centrifugal pump moved by it (7), which has at least one centrifugal impeller (10), creates a major inlet stream (29) through the annular space (12), as well as stream (30) coolant through space (28) surrounding the engine (8). This annular space (12) is divided by two guide vanes (22) into separate annular spaces (23, 24) which, during operation, have different pressure levels. Each individual annular space (23, 24) is connected to the space (28) surrounding the motor (8) through which the flow of coolant flows.
EFFECT: ensuring sufficient cooling of the engine without directing the main pumping flow along the engine.
