PULSATION VALVE SUBMERSIBLE PUMP Russian patent published in 2013 - IPC G21F9/34 F04F1/02 

FIELD: power engineering.

SUBSTANCE: in a pulsation valve submersible pump comprising a body, a pulse line, an inlet ball valve with a limiter of ball raising, an injection pipeline with an outlet ball valve, a chamber of lower nozzles, inside of which there is a shaft, which connects lower nozzles with a rotation drive and a control system, the chamber of lower nozzles is arranged in the body beyond a partition, which separates the body into the chamber of lower nozzles and a discharge chamber. The chamber of lower nozzles and the discharge chamber communicate with each other via a gap above the partition installed under the pulse line inlet into the body. In the partition there is a hole, in which there is a relief valve with a ball floating in water.

EFFECT: invention makes it possible to expand process capabilities of a pump due to realisation of simultaneous mixing and discharge of a suspension from a reservoir, and to increase efficiency of its operation.
