FIELD: machine building.
SUBSTANCE: installation is designed for implementation in various branches of industry for transfer of liquid or viscous products by pumping-over. The installation has a tank, a pump for pumping liquid off, and of a vacuum pump. The tank functions as an intermediate reservoir; the vacuum pump is connected to the tank by means of a pipeline; while the pump for pumping liquid off is arranged directly under the tank. There are installed the pipeline of liquid intake line, and a floating valve installed in the tank for closing the pipeline connected to the vacuum pump at excess of specified level of liquid in the tank and for opening this pipeline at decrease of specified level in the tank.
EFFECT: raised efficiency, improved reliability and simplification of design.
