Vertical pumps
Vertical sand pumps of PRV type in the gummed version with the supply from 50 to 1250 m3/h and the pressure from 12.5 to 15 m are designed for dressing products pumping with the mass density up to 2.2 t/m3 and the volume concentration up to 30% with hard inserts with coarseness up to 3 mm and hydrogen indexes of the transported environment of рН 5.5 — 12. The pumps contraction is designed for operation in close premises at the ambient air temperature from +5 to +60°С. The pumps of PRV type are one stage immersed with vertical shaft position.
