FIELD: oil and gas well construction, particularly devices to intensify chemical reagent dissolving in liquid, to activate sticky cement and powder and granular material dispersion.

SUBSTANCE: hydraulic disperser comprises hollow two-stage body with connection threads formed at body ends and cup installed in body section having greater diameter so that the cup is spaced from body wall and cup bottom faces outlet orifice of body section having lesser diameter. The cup is provided with inner and outer connection threads formed from opened end side of the cup. Opposite nozzles are installed in side orifices of the cup so that nozzle axes are transversal to central body axis. Outlet orifice of body section having lesser diameter is provided with screwed-on nozzle. Cup bottom from outer side is provided with wear-resistant screen insert, which is opposite to body nozzle.
