FIELD: pump building.
SUBSTANCE: invention relates to the field of pump engineering, namely to multistage centrifugal pumps, which are used for pumping liquid. Pump consists of four pumps, in which impellers are installed on one drive shaft and connected through safety coupling with electric motor, and the pumps are connected to each other by transition chambers equipped with inlet and outlet channels, at the same time two-way valves are installed on the supply channels, and four-way valves are installed on the outlet ones with the possibility of controlling the pump operation modes.
EFFECT: device makes it possible to readjust the operating mode during operation, and therefore, expands technological capabilities.
