Device is furnished with hydrocyclones, pneumohydraulic accumulators and two-position flow distributor. Housing of distributor is hydraulically coupled through branch pipes with upper and lower water-distributing systems to supply water from pond and let out cleaned water. Plunger of distributor is mechanically coupled with diaphragm of pneumohydraulic accumulator. Hydraulic space of pneumohydraulic accumulator is connected by valves with system to let out cleaned water and impurities removal network. Upper and lower distributing system of sealed reservoir are connected by two-position water flow distributor with impurities removal network and cyclones installed in tandem at inlet outlet of hydraulic system. Self-cleaning gauze filters are installed in cyclone space. Bottom parts of cyclones are mated with impurities accumulators.

EFFECT: reduced cost of crop products, increased operation reliability and reduced labor input at servicing of plant.
