FIELD: fire safety.
SUBSTANCE: device contains a water intake probe (1), a non-return valve (2), a flexible vacuum tube (3), a device for transporting liquid from the pumped volume to the outside. A diaphragm pump (4) with a single-motorized drive is used as a device. The non-return valve (2) is installed in the upper part of the water intake probe (1) and connected to the diaphragm pump (4) via a flexible vacuum tube (3) containing the make-up tap (7) connected to it.
EFFECT: simplified design, reduced overall dimensions, no need to connect to a stationary power source, increased device performance, simplified maintenance and enhanced functionality.
