FIELD: pumping equipment.
SUBSTANCE: invention can be used for pumping out of containers. Centrifugal pump with a flow part immersed into the pumped medium comprises an engine, a support plate, a shaft line formed by one or more suspensions, a seal assembly, formed by two end seals and chamber with barrier or gate fluid between them. Pump is equipped with a system for monitoring the state of the barrier or gate liquid, comprising at least a liquid level meter and a pressure measurement device, each of which has indicator part and part reacting to fluid parameter change. Parts reacting to change of fluid parameter are located between two end seals, directly in chamber with barrier or breech liquid.
EFFECT: invention is aimed at improving reliability of centrifugal pump operation and reducing probability of its unpredictable failures.
